+### Feature/API complete
+
+Idiorm is now considered to be feature complete as of version 1.5.0. Whilst it will continue to be maintained with bug fixes there will be no further new features added from this point on. This means that if a pull request makes breaking changes to the API or requires anything other than a patch version bump of the library then it will not be merged.
+
+**Please do not submit feature requests or API breaking changes as they will be closed without ceremony.**
+
+---
+
+A lightweight nearly-zero-configuration object-relational mapper and fluent query builder for PHP5 and above.
+
+Tested on PHP 5.2.0+ - may work on earlier versions with PDO and the correct database drivers.
+
+Released under a [BSD license](http://en.wikipedia.org/wiki/BSD_licenses).
+
+**See Also: [Paris](http://github.com/j4mie/paris), an Active Record implementation built on top of Idiorm.**
+
+Features
+--------
+
+* Makes simple queries and simple CRUD operations completely painless.
+* Gets out of the way when more complex SQL is required.
+* Built on top of [PDO](http://php.net/pdo).
+* Uses [prepared statements](http://uk.php.net/manual/en/pdo.prepared-statements.php) throughout to protect against [SQL injection](http://en.wikipedia.org/wiki/SQL_injection) attacks.
+* Requires no model classes, no XML configuration and no code generation: works out of the box, given only a connection string.
+* Consists of one main class called `ORM`. Additional classes are prefixed with `Idiorm`. Minimal global namespace pollution.
+* Database agnostic. Currently supports SQLite, MySQL, Firebird and PostgreSQL. May support others, please give it a try!
+* Supports collections of models with method chaining to filter or apply actions to multiple results at once.
+* Multiple connections supported
+* PSR-1 compliant methods (any method can be called in camelCase instead of underscores eg. `find_many()` becomes `findMany()`) - you'll need PHP 5.3+
+
+Documentation
+-------------
+
+The documentation is hosted on Read the Docs: [idiorm.rtfd.org](http://idiorm.rtfd.org)
+
+### Building the Docs ###
+
+You will need to install [Sphinx](http://sphinx-doc.org/) and then in the docs folder run:
+
+    make html
+
+The documentation will now be in docs/_build/html/index.html
+
+Let's See Some Code
+-------------------
+
+```php
+$user = ORM::for_table('user')
+    ->where_equal('username', 'j4mie')
+    ->find_one();
+
+$user->first_name = 'Jamie';
+$user->save();
+
+$tweets = ORM::for_table('tweet')
+    ->select('tweet.*')
+    ->join('user', array(
+        'user.id', '=', 'tweet.user_id'
+    ))
+    ->where_equal('user.username', 'j4mie')
+    ->find_many();
+
+foreach ($tweets as $tweet) {
+    echo $tweet->text;
+}
+```
+
+Tests
+-----
+
+Tests are written with PHPUnit and be run through composer
+
+    composer test
+
+To make testing on PHP 5.2 (Idiorm maintains support back to this version of PHP) there
+is a Docker setup in `./test/docker_for_php52` - check the readme in there for more.

+Configuration
+=============
+
+The first thing you need to know about Idiorm is that *you don’t need to
+define any model classes to use it*. With almost every other ORM, the
+first thing to do is set up your models and map them to database tables
+(through configuration variables, XML files or similar). With Idiorm,
+you can start using the ORM straight away.
+
+Setup
+~~~~~
+
+First, ``require`` the Idiorm source file:
+
+.. code-block:: php
+
+    <?php
+    require_once 'idiorm.php';
+
+Then, pass a *Data Source Name* connection string to the ``configure``
+method of the ORM class. This is used by PDO to connect to your
+database. For more information, see the `PDO documentation`_.
+
+.. code-block:: php
+
+    <?php
+    ORM::configure('sqlite:./example.db');
+
+You may also need to pass a username and password to your database
+driver, using the ``username`` and ``password`` configuration options.
+For example, if you are using MySQL:
+
+.. code-block:: php
+
+    <?php
+    ORM::configure('mysql:host=localhost;dbname=my_database');
+    ORM::configure('username', 'database_user');
+    ORM::configure('password', 'top_secret');
+
+Also see “Configuration” section below.
+
+Configuration
+~~~~~~~~~~~~~
+
+Other than setting the DSN string for the database connection (see
+above), the ``configure`` method can be used to set some other simple
+options on the ORM class. Modifying settings involves passing a
+key/value pair to the ``configure`` method, representing the setting you
+wish to modify and the value you wish to set it to.
+
+.. code-block:: php
+
+    <?php
+    ORM::configure('setting_name', 'value_for_setting');
+
+A shortcut is provided to allow passing multiple key/value pairs at
+once.
+
+.. code-block:: php
+
+    <?php
+    ORM::configure(array(
+        'setting_name_1' => 'value_for_setting_1', 
+        'setting_name_2' => 'value_for_setting_2', 
+        'etc' => 'etc'
+    ));
+
+Use the ``get_config`` method to read current settings.
+
+.. code-block:: php
+
+    <?php
+    $isLoggingEnabled = ORM::get_config('logging');
+    ORM::configure('logging', false);
+    // some crazy loop we don't want to log
+    ORM::configure('logging', $isLoggingEnabled);
+
+Database authentication details
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Settings: ``username`` and ``password``
+
+Some database adapters (such as MySQL) require a username and password
+to be supplied separately to the DSN string. These settings allow you to
+provide these values. A typical MySQL connection setup might look like
+this:
+
+.. code-block:: php
+
+    <?php
+    ORM::configure('mysql:host=localhost;dbname=my_database');
+    ORM::configure('username', 'database_user');
+    ORM::configure('password', 'top_secret');
+
+Or you can combine the connection setup into a single line using the
+configuration array shortcut:
+
+.. code-block:: php
+
+    <?php
+    ORM::configure(array(
+        'connection_string' => 'mysql:host=localhost;dbname=my_database', 
+        'username' => 'database_user', 
+        'password' => 'top_secret'
+    ));
+
+Result sets
+^^^^^^^^^^^
+
+Setting: ``return_result_sets``
+
+Collections of results can be returned as an array (default) or as a result set.
+See the `find_result_set()` documentation for more information.
+
+.. code-block:: php
+
+    <?php
+    ORM::configure('return_result_sets', true); // returns result sets
+
+
+.. note::
+
+   It is recommended that you setup your projects to use result sets as they
+   are more flexible.
+
+PDO Driver Options
+^^^^^^^^^^^^^^^^^^
+
+Setting: ``driver_options``
+
+Some database adapters require (or allow) an array of driver-specific
+configuration options. This setting allows you to pass these options
+through to the PDO constructor. For more information, see `the PDO
+documentation`_. For example, to force the MySQL driver to use UTF-8 for
+the connection:
+
+.. code-block:: php
+
+    <?php
+    ORM::configure('driver_options', array(PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8'));
+
+PDO Error Mode
+^^^^^^^^^^^^^^
+
+Setting: ``error_mode``
+
+This can be used to set the ``PDO::ATTR_ERRMODE`` setting on the
+database connection class used by Idiorm. It should be passed one of the
+class constants defined by PDO. For example:
+
+.. code-block:: php
+
+    <?php
+    ORM::configure('error_mode', PDO::ERRMODE_WARNING);
+
+The default setting is ``PDO::ERRMODE_EXCEPTION``. For full details of
+the error modes available, see `the PDO set attribute documentation`_.
+
+PDO object access
+^^^^^^^^^^^^^^^^^
+
+Should it ever be necessary, the PDO object used by Idiorm may be
+accessed directly through ``ORM::get_db()``, or set directly via
+``ORM::set_db()``. This should be an unusual occurance.
+
+After a statement has been executed by any means, such as ``::save()``
+or ``::raw_execute()``, the ``PDOStatement`` instance used may be
+accessed via ``ORM::get_last_statement()``. This may be useful in order
+to access ``PDOStatement::errorCode()``, if PDO exceptions are turned
+off, or to access the ``PDOStatement::rowCount()`` method, which returns
+differing results based on the underlying database. For more
+information, see the `PDOStatement documentation`_.
+
+Identifier quote character
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Setting: ``identifier_quote_character``
+
+Set the character used to quote identifiers (eg table name, column
+name). If this is not set, it will be autodetected based on the database
+driver being used by PDO.
+
+ID Column
+^^^^^^^^^
+
+By default, the ORM assumes that all your tables have a primary key
+column called ``id``. There are two ways to override this: for all
+tables in the database, or on a per-table basis.
+
+Setting: ``id_column``
+
+This setting is used to configure the name of the primary key column for
+all tables. If your ID column is called ``primary_key``, use:
+
+.. code-block:: php
+
+    <?php
+    ORM::configure('id_column', 'primary_key');
+
+You can specify a compound primary key using an array:
+
+.. code-block:: php
+
+    <?php
+    ORM::configure('id_column', array('pk_1', 'pk_2'));
+
+Note: If you use a auto-increment column in the compound primary key then it
+should be the first one defined into the array.
+
+Setting: ``id_column_overrides``
+
+This setting is used to specify the primary key column name for each
+table separately. It takes an associative array mapping table names to
+column names. If, for example, your ID column names include the name of
+the table, you can use the following configuration:
+
+.. code-block:: php
+
+    <?php
+    ORM::configure('id_column_overrides', array(
+        'person' => 'person_id',
+        'role' => 'role_id',
+    ));
+
+As with ``id_column`` setting, you can specify a compound primary key
+using an array.
+
+Limit clause style
+^^^^^^^^^^^^^^^^^^
+
+Setting: ``limit_clause_style``
+
+You can specify the limit clause style in the configuration. This is to facilitate
+a MS SQL style limit clause that uses the ``TOP`` syntax.
+
+Acceptable values are ``ORM::LIMIT_STYLE_TOP_N`` and ``ORM::LIMIT_STYLE_LIMIT``.
+
+.. note::
+
+    If the PDO driver you are using is one of sqlsrv, dblib or mssql then Idiorm
+    will automatically select the ``ORM::LIMIT_STYLE_TOP_N`` for you unless you
+    override the setting.
+
+Query logging
+^^^^^^^^^^^^^
+
+Setting: ``logging``
+
+Idiorm can log all queries it executes. To enable query logging, set the
+``logging`` option to ``true`` (it is ``false`` by default).
+
+When query logging is enabled, you can use two static methods to access
+the log. ``ORM::get_last_query()`` returns the most recent query
+executed. ``ORM::get_query_log()`` returns an array of all queries
+executed.
+
+.. note::
+
+    The code that does the query log is an approximation of that provided by PDO/the
+    database (see the Idiorm source code for detail). The actual query isn't even available
+    to idiorm to log as the database/PDO handles the binding outside of idiorm's reach and
+    doesn't pass it back.
+
+    This means that you might come across some inconsistencies between what is logged and
+    what is actually run. In these case you'll need to look at the query log provided by
+    your database vendor (eg. MySQL).
+
+Query logger
+^^^^^^^^^^^^
+
+Setting: ``logger``
+
+.. note::
+
+    You must enable ``logging`` for this setting to have any effect.
+
+It is possible to supply a ``callable`` to this configuration setting, which will
+be executed for every query that idiorm executes. In PHP a ``callable`` is anything
+that can be executed as if it were a function. Most commonly this will take the
+form of a anonymous function.
+
+This setting is useful if you wish to log queries with an external library as it
+allows you too whatever you would like from inside the callback function.
+
+.. code-block:: php
+
+    <?php
+    ORM::configure('logger', function($log_string, $query_time) {
+        echo $log_string . ' in ' . $query_time;
+    });
+
+Query caching
+^^^^^^^^^^^^^
+
+Setting: ``caching``
+
+Idiorm can cache the queries it executes during a request. To enable
+query caching, set the ``caching`` option to ``true`` (it is ``false``
+by default).
+
+.. code-block:: php
+
+    <?php
+    ORM::configure('caching', true);
+    
+    
+Setting: ``caching_auto_clear``
+
+Idiorm's cache is never cleared by default. If you wish to automatically clear it on save, set ``caching_auto_clear`` to ``true``
+
+.. code-block:: php
+
+    <?php
+    ORM::configure('caching_auto_clear', true);
+
+When query caching is enabled, Idiorm will cache the results of every
+``SELECT`` query it executes. If Idiorm encounters a query that has
+already been run, it will fetch the results directly from its cache and
+not perform a database query.
+
+Warnings and gotchas
+''''''''''''''''''''
+
+-  Note that this is an in-memory cache that only persists data for the
+   duration of a single request. This is *not* a replacement for a
+   persistent cache such as `Memcached`_.
+
+-  Idiorm’s cache is very simple, and does not attempt to invalidate
+   itself when data changes. This means that if you run a query to
+   retrieve some data, modify and save it, and then run the same query
+   again, the results will be stale (ie, they will not reflect your
+   modifications). This could potentially cause subtle bugs in your
+   application. If you have caching enabled and you are experiencing odd
+   behaviour, disable it and try again. If you do need to perform such
+   operations but still wish to use the cache, you can call the
+   ``ORM::clear_cache()`` to clear all existing cached queries.
+
+-  Enabling the cache will increase the memory usage of your
+   application, as all database rows that are fetched during each
+   request are held in memory. If you are working with large quantities
+   of data, you may wish to disable the cache.
+
+Custom caching
+''''''''''''''
+
+If you wish to use custom caching functions, you can set them from the configure options. 
+
+.. code-block:: php
+
+    <?php
+    $my_cache = array();
+    ORM::configure('cache_query_result', function ($cache_key, $value, $table_name, $connection_name) use (&$my_cache) {
+        $my_cache[$cache_key] = $value;
+    });
+    ORM::configure('check_query_cache', function ($cache_key, $table_name, $connection_name) use (&$my_cache) {
+        if(isset($my_cache[$cache_key])){
+           return $my_cache[$cache_key];
+        } else {
+        return false;
+        }
+    });
+    ORM::configure('clear_cache', function ($table_name, $connection_name) use (&$my_cache) {
+         $my_cache = array();
+    });
+
+    ORM::configure('create_cache_key', function ($query, $parameters, $table_name, $connection_name) {
+        $parameter_string = join(',', $parameters);
+        $key = $query . ':' . $parameter_string;
+        $my_key = 'my-prefix'.crc32($key);
+        return $my_key;
+    });

+Multiple Connections
+====================
+Idiorm now works with multiple conections. Most of the static functions
+work with an optional connection name as an extra parameter. For the
+``ORM::configure`` method, this means that when passing connection
+strings for a new connection, the second parameter, which is typically
+omitted, should be ``null``. In all cases, if a connection name is not
+provided, it defaults to ``ORM::DEFAULT_CONNECTION``.
+
+When chaining, once ``for_table()`` has been used in the chain, remaining
+calls in the chain use the correct connection.
+
+.. code-block:: php
+
+    <?php
+    // Default connection
+    ORM::configure('sqlite:./example.db');
+
+    // A named connection, where 'remote' is an arbitrary key name
+    ORM::configure('mysql:host=localhost;dbname=my_database', null, 'remote');
+    ORM::configure('username', 'database_user', 'remote');
+    ORM::configure('password', 'top_secret', 'remote');
+    
+    // Using default connection
+    $person = ORM::for_table('person')->find_one(5);
+    
+    // Using default connection, explicitly
+    $person = ORM::for_table('person', ORM::DEFAULT_CONNECTION)->find_one(5);
+    
+    // Using named connection
+    $person = ORM::for_table('different_person', 'remote')->find_one(5);
+    
+    
+
+Supported Methods
+^^^^^^^^^^^^^^^^^
+In each of these cases, the ``$connection_name`` parameter is optional, and is
+an arbitrary key identifying the named connection.
+
+* ``ORM::configure($key, $value, $connection_name)``
+* ``ORM::for_table($table_name, $connection_name)``
+* ``ORM::set_db($pdo, $connection_name)``
+* ``ORM::get_db($connection_name)``
+* ``ORM::raw_execute($query, $parameters, $connection_name)``
+* ``ORM::get_last_query($connection_name)``
+* ``ORM::get_query_log($connection_name)``
+
+Of these methods, only ``ORM::get_last_query($connection_name)`` does *not*
+fallback to the default connection when no connection name is passed.
+Instead, passing no connection name (or ``null``) returns the most recent
+query on *any* connection.
+
+.. code-block:: php
+
+    <?php
+    // Using default connection, explicitly
+    $person = ORM::for_table('person')->find_one(5);
+    
+    // Using named connection
+    $person = ORM::for_table('different_person', 'remote')->find_one(5);
+
+    // Last query on *any* connection
+    ORM::get_last_query(); // returns query on 'different_person' using 'remote'
+    
+    // returns query on 'person' using default by passing in the connection name
+    ORM::get_last_query(ORM::DEFAULT_CONNECTION);
+
+Notes
+~~~~~
+* **There is no support for joins across connections**
+* Multiple connections do not share configuration settings. This means if
+  one connection has logging set to ``true`` and the other does not, only
+  queries from the logged connection will be available via
+  ``ORM::get_last_query()`` and ``ORM::get_query_log()``.
+* A new method has been added, ``ORM::get_connection_names()``, which returns
+  an array of connection names.
+* Caching *should* work with multiple connections (remember to turn caching
+  on for each connection), but the unit tests are not robust. Please report
+  any errors.

+Models
+======
+
+Getting data from objects
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Once you've got a set of records (objects) back from a query, you can
+access properties on those objects (the values stored in the columns in
+its corresponding table) in two ways: by using the ``get`` method, or
+simply by accessing the property on the object directly:
+
+.. code-block:: php
+
+    <?php
+    $person = ORM::for_table('person')->find_one(5);
+
+    // The following two forms are equivalent
+    $name = $person->get('name');
+    $name = $person->name;
+
+You can also get the all the data wrapped by an ORM instance using the
+``as_array`` method. This will return an associative array mapping
+column names (keys) to their values.
+
+The ``as_array`` method takes column names as optional arguments. If one
+or more of these arguments is supplied, only matching column names will
+be returned.
+
+.. code-block:: php
+
+    <?php
+    $person = ORM::for_table('person')->create();
+
+    $person->first_name = 'Fred';
+    $person->surname = 'Bloggs';
+    $person->age = 50;
+
+    // Returns array('first_name' => 'Fred', 'surname' => 'Bloggs', 'age' => 50)
+    $data = $person->as_array();
+
+    // Returns array('first_name' => 'Fred', 'age' => 50)
+    $data = $person->as_array('first_name', 'age');
+
+Updating records
+~~~~~~~~~~~~~~~~
+
+To update the database, change one or more of the properties of the
+object, then call the ``save`` method to commit the changes to the
+database. Again, you can change the values of the object's properties
+either by using the ``set`` method or by setting the value of the
+property directly. By using the ``set`` method it is also possible to
+update multiple properties at once, by passing in an associative array:
+
+.. code-block:: php
+
+    <?php
+    $person = ORM::for_table('person')->find_one(5);
+
+    // The following two forms are equivalent
+    $person->set('name', 'Bob Smith');
+    $person->age = 20;
+
+    // This is equivalent to the above two assignments
+    $person->set(array(
+        'name' => 'Bob Smith',
+        'age'  => 20
+    ));
+
+    // Syncronise the object with the database
+    $person->save();
+
+Properties containing expressions
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+It is possible to set properties on the model that contain database
+expressions using the ``set_expr`` method.
+
+.. code-block:: php
+
+    <?php
+    $person = ORM::for_table('person')->find_one(5);
+    $person->set('name', 'Bob Smith');
+    $person->age = 20;
+    $person->set_expr('updated', 'NOW()');
+    $person->save();
+
+The ``updated`` column's value will be inserted into query in its raw
+form therefore allowing the database to execute any functions referenced
+- such as ``NOW()`` in this case.
+
+Creating new records
+~~~~~~~~~~~~~~~~~~~~
+
+To add a new record, you need to first create an "empty" object
+instance. You then set values on the object as normal, and save it.
+
+.. code-block:: php
+
+    <?php
+    $person = ORM::for_table('person')->create();
+
+    $person->name = 'Joe Bloggs';
+    $person->age = 40;
+
+    $person->save();
+
+After the object has been saved, you can call its ``id()`` method to
+find the autogenerated primary key value that the database assigned to
+it.
+
+Properties containing expressions
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+It is possible to set properties on the model that contain database
+expressions using the ``set_expr`` method.
+
+.. code-block:: php
+
+    <?php
+    $person = ORM::for_table('person')->create();
+    $person->set('name', 'Bob Smith');
+    $person->age = 20;
+    $person->set_expr('added', 'NOW()');
+    $person->save();
+
+The ``added`` column's value will be inserted into query in its raw form
+therefore allowing the database to execute any functions referenced -
+such as ``NOW()`` in this case.
+
+Checking whether a property has been modified
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To check whether a property has been changed since the object was
+created (or last saved), call the ``is_dirty`` method:
+
+.. code-block:: php
+
+    <?php
+    $name_has_changed = $person->is_dirty('name'); // Returns true or false
+
+Deleting records
+~~~~~~~~~~~~~~~~
+
+To delete an object from the database, simply call its ``delete``
+method.
+
+.. code-block:: php
+
+    <?php
+    $person = ORM::for_table('person')->find_one(5);
+    $person->delete();
+
+To delete more than one object from the database, build a query:
+
+.. code-block:: php
+
+    <?php
+    $person = ORM::for_table('person')
+        ->where_equal('zipcode', 55555)
+        ->delete_many();

+Philosophy
+==========
+
+The `Pareto Principle`_ states that *roughly 80% of the effects come
+from 20% of the causes.* In software development terms, this could be
+translated into something along the lines of *80% of the results come
+from 20% of the complexity*. In other words, you can get pretty far by
+being pretty stupid.
+
+**Idiorm is deliberately simple**. Where other ORMs consist of dozens of
+classes with complex inheritance hierarchies, Idiorm has only one class,
+``ORM``, which functions as both a fluent ``SELECT`` query API and a
+simple CRUD model class. If my hunch is correct, this should be quite
+enough for many real-world applications. Let’s face it: most of us
+aren’t building Facebook. We’re working on small-to-medium-sized
+projects, where the emphasis is on simplicity and rapid development
+rather than infinite flexibility and features.
+
+You might think of **Idiorm** as a *micro-ORM*. It could, perhaps, be
+“the tie to go along with `Slim`_\ ’s tux” (to borrow a turn of phrase
+from `DocumentCloud`_). Or it could be an effective bit of spring
+cleaning for one of those horrendous SQL-littered legacy PHP apps you
+have to support.
+
+**Idiorm** might also provide a good base upon which to build
+higher-level, more complex database abstractions. For example, `Paris`_
+is an implementation of the `Active Record pattern`_ built on top of
+Idiorm.

+Querying
+========
+
+Idiorm provides a `*fluent
+interface* <http://en.wikipedia.org/wiki/Fluent_interface>`_ to enable
+simple queries to be built without writing a single character of SQL. If
+you've used `jQuery <http://jquery.com>`_ at all, you'll be familiar
+with the concept of a fluent interface. It just means that you can
+*chain* method calls together, one after another. This can make your
+code more readable, as the method calls strung together in order can
+start to look a bit like a sentence.
+
+All Idiorm queries start with a call to the ``for_table`` static method
+on the ORM class. This tells the ORM which table to use when making the
+query.
+
+*Note that this method **does not** escape its query parameter and so
+the table name should **not** be passed directly from user input.*
+
+Method calls which add filters and constraints to your query are then
+strung together. Finally, the chain is finished by calling either
+``find_one()`` or ``find_many()``, which executes the query and returns
+the result.
+
+Let's start with a simple example. Say we have a table called ``person``
+which contains the columns ``id`` (the primary key of the record -
+Idiorm assumes the primary key column is called ``id`` but this is
+configurable, see below), ``name``, ``age`` and ``gender``.
+
+A note on PSR-1 and camelCase
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+All the methods detailed in the documentation can also be called in a PSR-1 way:
+underscores (_) become camelCase. Here follows an example of one query chain
+being converted to a PSR-1 compliant style.
+
+.. code-block:: php
+
+    <?php
+    // documented and default style
+    $person = ORM::for_table('person')->where('name', 'Fred Bloggs')->find_one();
+
+    // PSR-1 compliant style
+    $person = ORM::forTable('person')->where('name', 'Fred Bloggs')->findOne();
+
+As you can see any method can be changed from the documented underscore (_) format
+to that of a camelCase method name.
+
+.. note::
+
+    In the background the PSR-1 compliant style uses the `__call()` and 
+    `__callStatic()` magic methods to map the camelCase method name you supply
+    to the original underscore method name. It then uses `call_user_func_array()`
+    to apply the arguments to the method. If this minimal overhead is too great
+    then you can simply revert to using the underscore methods to avoid it. In
+    general this will not be a bottle neck in any application however and should
+    be considered a micro-optimisation.
+
+    As `__callStatic()` was added in PHP 5.3.0 you will need at least that version
+    of PHP to use this feature in any meaningful way.
+
+Single records
+^^^^^^^^^^^^^^
+
+Any method chain that ends in ``find_one()`` will return either a
+*single* instance of the ORM class representing the database row you
+requested, or ``false`` if no matching record was found.
+
+To find a single record where the ``name`` column has the value "Fred
+Bloggs":
+
+.. code-block:: php
+
+    <?php
+    $person = ORM::for_table('person')->where('name', 'Fred Bloggs')->find_one();
+
+This roughly translates into the following SQL:
+``SELECT * FROM person WHERE name = "Fred Bloggs"``
+
+To find a single record by ID, you can pass the ID directly to the
+``find_one`` method:
+
+.. code-block:: php
+
+    <?php
+    $person = ORM::for_table('person')->find_one(5);
+
+If you are using a compound primary key, you can find the records
+using an array as the parameter:
+
+.. code-block:: php
+
+    <?php
+    $person = ORM::for_table('user_role')->find_one(array(
+        'user_id' => 34,
+        'role_id' => 10
+    ));
+
+
+Multiple records
+^^^^^^^^^^^^^^^^
+
+.. note::
+
+   It is recommended that you use results sets over arrays - see `As a result set`
+   below.
+
+Any method chain that ends in ``find_many()`` will return an *array* of
+ORM class instances, one for each row matched by your query. If no rows
+were found, an empty array will be returned.
+
+To find all records in the table:
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')->find_many();
+
+To find all records where the ``gender`` is ``female``:
+
+.. code-block:: php
+
+    <?php
+    $females = ORM::for_table('person')->where('gender', 'female')->find_many();
+
+As a result set
+'''''''''''''''
+
+.. note::
+
+   There is a configuration setting ``return_result_sets`` that will cause
+   ``find_many()`` to return result sets by default. It is recommended that you
+   turn this setting on:
+
+   ::
+
+       ORM::configure('return_result_sets', true);
+
+You can also find many records as a result set instead of an array of Idiorm
+instances. This gives you the advantage that you can run batch operations on a
+set of results.
+
+So for example instead of running this:
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')->find_many();
+    foreach ($people as $person) {
+        $person->age = 50;
+        $person->save();
+    }
+
+You can simply do this instead:
+
+.. code-block:: php
+
+    <?php
+    ORM::for_table('person')->find_result_set()
+    ->set('age', 50)
+    ->save();
+
+To do this substitute any call to ``find_many()`` with
+``find_result_set()``.
+
+A result set will also behave like an array so you can `count()` it and `foreach`
+over it just like an array.
+
+.. code-block:: php
+
+    <?php
+    foreach(ORM::for_table('person')->find_result_set() as $record) {
+        echo $record->name;
+    }
+
+.. code-block:: php
+
+    <?php
+    echo count(ORM::for_table('person')->find_result_set());
+
+.. note::
+   
+   For deleting many records it is recommended that you use `delete_many()` as it
+   is more efficient than calling `delete()` on a result set.
+
+As an associative array
+'''''''''''''''''''''''
+
+You can also find many records as an associative array instead of Idiorm
+instances. To do this substitute any call to ``find_many()`` with
+``find_array()``.
+
+.. code-block:: php
+
+    <?php
+    $females = ORM::for_table('person')->where('gender', 'female')->find_array();
+
+This is useful if you need to serialise the the query output into a
+format like JSON and you do not need the ability to update the returned
+records.
+
+Counting results
+^^^^^^^^^^^^^^^^
+
+To return a count of the number of rows that would be returned by a
+query, call the ``count()`` method.
+
+.. code-block:: php
+
+    <?php
+    $number_of_people = ORM::for_table('person')->count();
+
+Filtering results
+^^^^^^^^^^^^^^^^^
+
+Idiorm provides a family of methods to extract only records which
+satisfy some condition or conditions. These methods may be called
+multiple times to build up your query, and Idiorm's fluent interface
+allows method calls to be *chained* to create readable and
+simple-to-understand queries.
+
+*Caveats*
+'''''''''
+
+Only a subset of the available conditions supported by SQL are available
+when using Idiorm. Additionally, all the ``WHERE`` clauses will be
+``AND``\ ed together when the query is run. Support for ``OR``\ ing
+``WHERE`` clauses is not currently present.
+
+These limits are deliberate: these are by far the most commonly used
+criteria, and by avoiding support for very complex queries, the Idiorm
+codebase can remain small and simple.
+
+Some support for more complex conditions and queries is provided by the
+``where_raw`` and ``raw_query`` methods (see below). If you find
+yourself regularly requiring more functionality than Idiorm can provide,
+it may be time to consider using a more full-featured ORM.
+
+Equality: ``where``, ``where_equal``, ``where_not_equal``
+'''''''''''''''''''''''''''''''''''''''''''''''''''''''''
+
+By default, calling ``where`` with two parameters (the column name and
+the value) will combine them using an equals operator (``=``). For
+example, calling ``where('name', 'Fred')`` will result in the clause
+``WHERE name = "Fred"``.
+
+If your coding style favours clarity over brevity, you may prefer to use
+the ``where_equal`` method: this is identical to ``where``.
+
+The ``where_not_equal`` method adds a ``WHERE column != "value"`` clause
+to your query.
+
+You can specify multiple columns and their values in the same call. In this
+case you should pass an associative array as the first parameter. The array
+notation uses keys as column names.
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')
+                ->where(array(
+                    'name' => 'Fred',
+                    'age' => 20
+                ))
+                ->find_many();
+
+    // Creates SQL:
+    SELECT * FROM `person` WHERE `name` = "Fred" AND `age` = "20";
+
+Shortcut: ``where_id_is``
+'''''''''''''''''''''''''
+
+This is a simple helper method to query the table by primary key.
+Respects the ID column specified in the config. If you are using a compound
+primary key, you must pass an array where the key is the column name. Columns
+that don't belong to the key will be ignored.
+
+Shortcut: ``where_id_in``
+'''''''''''''''''''''''''
+
+This helper method is similar to ``where_id_is`, but it expects an array of
+primary keys to be selected. It is compound primary keys aware.
+
+Less than / greater than: ``where_lt``, ``where_gt``, ``where_lte``, ``where_gte``
+''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
+
+There are four methods available for inequalities:
+
+-  Less than:
+   ``$people = ORM::for_table('person')->where_lt('age', 10)->find_many();``
+-  Greater than:
+   ``$people = ORM::for_table('person')->where_gt('age', 5)->find_many();``
+-  Less than or equal:
+   ``$people = ORM::for_table('person')->where_lte('age', 10)->find_many();``
+-  Greater than or equal:
+   ``$people = ORM::for_table('person')->where_gte('age', 5)->find_many();``
+
+String comparision: ``where_like`` and ``where_not_like``
+'''''''''''''''''''''''''''''''''''''''''''''''''''''''''
+
+To add a ``WHERE ... LIKE`` clause, use:
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')->where_like('name', '%fred%')->find_many();
+
+Similarly, to add a ``WHERE ... NOT LIKE`` clause, use:
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')->where_not_like('name', '%bob%')->find_many();
+
+Multiple OR'ed conditions
+'''''''''''''''''''''''''
+
+You can add simple OR'ed conditions to the same WHERE clause using ``where_any_is``. You
+should specify multiple conditions using an array of items. Each item will be an
+associative array that contains a multiple conditions. 
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')
+                ->where_any_is(array(
+                    array('name' => 'Joe', 'age' => 10),
+                    array('name' => 'Fred', 'age' => 20)))
+                ->find_many();
+
+    // Creates SQL:
+    SELECT * FROM `widget` WHERE (( `name` = 'Joe' AND `age` = '10' ) OR ( `name` = 'Fred' AND `age` = '20' ));
+
+By default, it uses the equal operator for every column, but it can be overriden for any
+column using a second parameter:
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')
+                ->where_any_is(array(
+                    array('name' => 'Joe', 'age' => 10),
+                    array('name' => 'Fred', 'age' => 20)), array('age' => '>'))
+                ->find_many();
+
+    // Creates SQL:
+    SELECT * FROM `widget` WHERE (( `name` = 'Joe' AND `age` = '10' ) OR ( `name` = 'Fred' AND `age` > '20' ));
+
+If you want to set the default operator for all the columns, just pass it as the second parameter:
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')
+                ->where_any_is(array(
+                    array('score' => '5', 'age' => 10),
+                    array('score' => '15', 'age' => 20)), '>')
+                ->find_many();
+
+    // Creates SQL:
+    SELECT * FROM `widget` WHERE (( `score` > '5' AND `age` > '10' ) OR ( `score` > '15' AND `age` > '20' ));
+
+Set membership: ``where_in`` and ``where_not_in``
+'''''''''''''''''''''''''''''''''''''''''''''''''
+
+To add a ``WHERE ... IN ()`` or ``WHERE ... NOT IN ()`` clause, use the
+``where_in`` and ``where_not_in`` methods respectively.
+
+Both methods accept two arguments. The first is the column name to
+compare against. The second is an *array* of possible values. As all the
+``where_`` methods, you can specify multiple columns using an associative
+*array* as the only parameter.
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')->where_in('name', array('Fred', 'Joe', 'John'))->find_many();
+
+Working with ``NULL`` values: ``where_null`` and ``where_not_null``
+'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
+
+To add a ``WHERE column IS NULL`` or ``WHERE column IS NOT NULL``
+clause, use the ``where_null`` and ``where_not_null`` methods
+respectively. Both methods accept a single parameter: the column name to
+test.
+
+Raw WHERE clauses
+'''''''''''''''''
+
+If you require a more complex query, you can use the ``where_raw``
+method to specify the SQL fragment for the WHERE clause exactly. This
+method takes two arguments: the string to add to the query, and an
+(optional) array of parameters which will be bound to the string. If
+parameters are supplied, the string should contain question mark
+characters (``?``) to represent the values to be bound, and the
+parameter array should contain the values to be substituted into the
+string in the correct order.
+
+This method may be used in a method chain alongside other ``where_*``
+methods as well as methods such as ``offset``, ``limit`` and
+``order_by_*``. The contents of the string you supply will be connected
+with preceding and following WHERE clauses with AND.
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')
+                ->where('name', 'Fred')
+                ->where_raw('(`age` = ? OR `age` = ?)', array(20, 25))
+                ->order_by_asc('name')
+                ->find_many();
+
+    // Creates SQL:
+    SELECT * FROM `person` WHERE `name` = "Fred" AND (`age` = 20 OR `age` = 25) ORDER BY `name` ASC;
+
+.. note::
+
+    You must wrap your expression in parentheses when using any of ``ALL``,
+    ``ANY``, ``BETWEEN``, ``IN``, ``LIKE``, ``OR`` and ``SOME``. Otherwise
+    the precedence of ``AND`` will bind stronger and in the above example
+    you would effectively get ``WHERE (`name` = "Fred" AND `age` = 20) OR `age` = 25``
+
+Note that this method only supports "question mark placeholder" syntax,
+and NOT "named placeholder" syntax. This is because PDO does not allow
+queries that contain a mixture of placeholder types. Also, you should
+ensure that the number of question mark placeholders in the string
+exactly matches the number of elements in the array.
+
+If you require yet more flexibility, you can manually specify the entire
+query. See *Raw queries* below.
+
+Limits and offsets
+''''''''''''''''''
+
+*Note that these methods **do not** escape their query parameters and so
+these should **not** be passed directly from user input.*
+
+The ``limit`` and ``offset`` methods map pretty closely to their SQL
+equivalents.
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')->where('gender', 'female')->limit(5)->offset(10)->find_many();
+
+Ordering
+''''''''
+
+*Note that these methods **do not** escape their query parameters and so
+these should **not** be passed directly from user input.*
+
+Two methods are provided to add ``ORDER BY`` clauses to your query.
+These are ``order_by_desc`` and ``order_by_asc``, each of which takes a
+column name to sort by. The column names will be quoted.
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')->order_by_asc('gender')->order_by_desc('name')->find_many();
+
+If you want to order by something other than a column name, then use the
+``order_by_expr`` method to add an unquoted SQL expression as an
+``ORDER BY`` clause.
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')->order_by_expr('SOUNDEX(`name`)')->find_many();
+
+Grouping
+^^^^^^^^
+
+*Note that this method **does not** escape it query parameter and so
+this should **not** by passed directly from user input.*
+
+To add a ``GROUP BY`` clause to your query, call the ``group_by``
+method, passing in the column name. You can call this method multiple
+times to add further columns.
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')->where('gender', 'female')->group_by('name')->find_many();
+
+It is also possible to ``GROUP BY`` a database expression:
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')->where('gender', 'female')->group_by_expr("FROM_UNIXTIME(`time`, '%Y-%m')")->find_many();
+
+Having
+^^^^^^
+
+When using aggregate functions in combination with a ``GROUP BY`` you can use
+``HAVING`` to filter based on those values.
+
+``HAVING`` works in exactly the same way as all of the ``where*`` functions in Idiorm.
+Substitute ``where_`` for ``having_`` to make use of these functions.
+
+For example:
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')->group_by('name')->having_not_like('name', '%bob%')->find_many();
+
+Result columns
+^^^^^^^^^^^^^^
+
+By default, all columns in the ``SELECT`` statement are returned from
+your query. That is, calling:
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')->find_many();
+
+Will result in the query:
+
+.. code-block:: php
+
+    <?php
+    SELECT * FROM `person`;
+
+The ``select`` method gives you control over which columns are returned.
+Call ``select`` multiple times to specify columns to return or use
+```select_many`` <#shortcuts-for-specifying-many-columns>`_ to specify
+many columns at once.
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')->select('name')->select('age')->find_many();
+
+Will result in the query:
+
+.. code-block:: php
+
+    <?php
+    SELECT `name`, `age` FROM `person`;
+
+Optionally, you may also supply a second argument to ``select`` to
+specify an alias for the column:
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')->select('name', 'person_name')->find_many();
+
+Will result in the query:
+
+.. code-block:: php
+
+    <?php
+    SELECT `name` AS `person_name` FROM `person`;
+
+Column names passed to ``select`` are quoted automatically, even if they
+contain ``table.column``-style identifiers:
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')->select('person.name', 'person_name')->find_many();
+
+Will result in the query:
+
+.. code-block:: php
+
+    <?php
+    SELECT `person`.`name` AS `person_name` FROM `person`;
+
+If you wish to override this behaviour (for example, to supply a
+database expression) you should instead use the ``select_expr`` method.
+Again, this takes the alias as an optional second argument. You can
+specify multiple expressions by calling ``select_expr`` multiple times
+or use ```select_many_expr`` <#shortcuts-for-specifying-many-columns>`_
+to specify many expressions at once.
+
+.. code-block:: php
+
+    <?php
+    // NOTE: For illustrative purposes only. To perform a count query, use the count() method.
+    $people_count = ORM::for_table('person')->select_expr('COUNT(*)', 'count')->find_many();
+
+Will result in the query:
+
+.. code-block:: php
+
+    <?php
+    SELECT COUNT(*) AS `count` FROM `person`;
+
+Shortcuts for specifying many columns
+'''''''''''''''''''''''''''''''''''''
+
+``select_many`` and ``select_many_expr`` are very similar, but they
+allow you to specify more than one column at once. For example:
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')->select_many('name', 'age')->find_many();
+
+Will result in the query:
+
+.. code-block:: php
+
+    <?php
+    SELECT `name`, `age` FROM `person`;
+
+To specify aliases you need to pass in an array (aliases are set as the
+key in an associative array):
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')->select_many(array('first_name' => 'name'), 'age', 'height')->find_many();
+
+Will result in the query:
+
+.. code-block:: php
+
+    <?php
+    SELECT `name` AS `first_name`, `age`, `height` FROM `person`;
+
+You can pass the the following styles into ``select_many`` and
+``select_many_expr`` by mixing and matching arrays and parameters:
+
+.. code-block:: php
+
+    <?php
+    select_many(array('alias' => 'column', 'column2', 'alias2' => 'column3'), 'column4', 'column5')
+    select_many('column', 'column2', 'column3')
+    select_many(array('column', 'column2', 'column3'), 'column4', 'column5')
+
+All the select methods can also be chained with each other so you could
+do the following to get a neat select query including an expression:
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')->select_many('name', 'age', 'height')->select_expr('NOW()', 'timestamp')->find_many();
+
+Will result in the query:
+
+.. code-block:: php
+
+    <?php
+    SELECT `name`, `age`, `height`, NOW() AS `timestamp` FROM `person`;
+
+DISTINCT
+^^^^^^^^
+
+To add a ``DISTINCT`` keyword before the list of result columns in your
+query, add a call to ``distinct()`` to your query chain.
+
+.. code-block:: php
+
+    <?php
+    $distinct_names = ORM::for_table('person')->distinct()->select('name')->find_many();
+
+This will result in the query:
+
+.. code-block:: php
+
+    <?php
+    SELECT DISTINCT `name` FROM `person`;
+
+Joins
+^^^^^
+
+Idiorm has a family of methods for adding different types of ``JOIN``\ s
+to the queries it constructs:
+
+Methods: ``join``, ``inner_join``, ``left_outer_join``,
+``right_outer_join``, ``full_outer_join``.
+
+Each of these methods takes the same set of arguments. The following
+description will use the basic ``join`` method as an example, but the
+same applies to each method.
+
+The first two arguments are mandatory. The first is the name of the
+table to join, and the second supplies the conditions for the join. The
+recommended way to specify the conditions is as an *array* containing
+three components: the first column, the operator, and the second column.
+The table and column names will be automatically quoted. For example:
+
+.. code-block:: php
+
+    <?php
+    $results = ORM::for_table('person')->join('person_profile', array('person.id', '=', 'person_profile.person_id'))->find_many();
+
+It is also possible to specify the condition as a string, which will be
+inserted as-is into the query. However, in this case the column names
+will **not** be escaped, and so this method should be used with caution.
+
+.. code-block:: php
+
+    <?php
+    // Not recommended because the join condition will not be escaped.
+    $results = ORM::for_table('person')->join('person_profile', 'person.id = person_profile.person_id')->find_many();
+
+The ``join`` methods also take an optional third parameter, which is an
+``alias`` for the table in the query. This is useful if you wish to join
+the table to *itself* to create a hierarchical structure. In this case,
+it is best combined with the ``table_alias`` method, which will add an
+alias to the *main* table associated with the ORM, and the ``select``
+method to control which columns get returned.
+
+.. code-block:: php
+
+    <?php
+    $results = ORM::for_table('person')
+        ->table_alias('p1')
+        ->select('p1.*')
+        ->select('p2.name', 'parent_name')
+        ->join('person', array('p1.parent', '=', 'p2.id'), 'p2')
+        ->find_many();
+
+Raw JOIN clauses
+'''''''''''''''''
+
+If you need to construct a more complex query, you can use the ``raw_join``
+method to specify the SQL fragment for the JOIN clause exactly. This
+method takes four required arguments: the string to add to the query,
+the conditions is as an *array* containing three components: 
+the first column, the operator, and the second column, the table alias and
+(optional) the parameters array. If parameters are supplied, 
+the string should contain question mark characters (``?``) to represent 
+the values to be bound, and the parameter array should contain the values 
+to be substituted into the string in the correct order.
+
+This method may be used in a method chain alongside other ``*_join``
+methods as well as methods such as ``offset``, ``limit`` and
+``order_by_*``. The contents of the string you supply will be connected
+with preceding and following JOIN clauses.
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')
+                ->raw_join(
+                    'JOIN (SELECT * FROM role WHERE role.name = ?)', 
+                    array('person.role_id', '=', 'role.id'), 
+                    'role', 
+                    array('role' => 'janitor'))    
+                ->order_by_asc('person.name')
+                ->find_many();
+
+    // Creates SQL:
+    SELECT * FROM `person` JOIN (SELECT * FROM role WHERE role.name = 'janitor') `role` ON `person`.`role_id` = `role`.`id` ORDER BY `person`.`name` ASC
+
+Note that this method only supports "question mark placeholder" syntax,
+and NOT "named placeholder" syntax. This is because PDO does not allow
+queries that contain a mixture of placeholder types. Also, you should
+ensure that the number of question mark placeholders in the string
+exactly matches the number of elements in the array.
+
+If you require yet more flexibility, you can manually specify the entire
+query. See *Raw queries* below.
+
+
+Aggregate functions
+^^^^^^^^^^^^^^^^^^^
+
+There is support for ``MIN``, ``AVG``, ``MAX`` and ``SUM`` in addition
+to ``COUNT`` (documented earlier).
+
+To return a minimum value of column, call the ``min()`` method.
+
+.. code-block:: php
+
+    <?php
+    $min = ORM::for_table('person')->min('height');
+
+The other functions (``AVG``, ``MAX`` and ``SUM``) work in exactly the
+same manner. Supply a column name to perform the aggregate function on
+and it will return an integer.
+
+Raw queries
+^^^^^^^^^^^
+
+If you need to perform more complex queries, you can completely specify
+the query to execute by using the ``raw_query`` method. This method
+takes a string and optionally an array of parameters. The string can
+contain placeholders, either in question mark or named placeholder
+syntax, which will be used to bind the parameters to the query.
+
+.. code-block:: php
+
+    <?php
+    $people = ORM::for_table('person')->raw_query('SELECT p.* FROM person p JOIN role r ON p.role_id = r.id WHERE r.name = :role', array('role' => 'janitor'))->find_many();
+
+The ORM class instance(s) returned will contain data for all the columns
+returned by the query. Note that you still must call ``for_table`` to
+bind the instances to a particular table, even though there is nothing
+to stop you from specifying a completely different table in the query.
+This is because if you wish to later called ``save``, the ORM will need
+to know which table to update.
+
+.. note::
+
+    Using ``raw_query`` is advanced and possibly dangerous, and
+    Idiorm does not make any attempt to protect you from making errors when
+    using this method. If you find yourself calling ``raw_query`` often, you
+    may have misunderstood the purpose of using an ORM, or your application
+    may be too complex for Idiorm. Consider using a more full-featured
+    database abstraction system.
+
+Raw SQL execution using PDO
+'''''''''''''''''''''''''''
+
+.. warning::
+
+    By using this function you're dropping down to PHPs PDO directly. Idiorm
+    does not make any attempt to protect you from making errors when using this
+    method.
+
+    You're essentially just using Idiorm to manage the connection and configuration
+    when you implement ``raw_execute()``.
+
+It can be handy, in some instances, to make use of the PDO instance underneath
+Idiorm to make advanced queries. These can be things like dropping a table from
+the database that Idiorm doesn't support and will not support in the future. These
+are operations that fall outside the 80/20 philosophy of Idiorm. That said there is
+a lot of interest in this function and quite a lot of support requests related to
+it.
+
+This method directly maps to `PDOStatement::execute()`_ underneath so please
+familiarise yourself with it's documentation.
+
+Dropping tables
+~~~~~~~~~~~~~~~
+
+This can be done very simply using ``raw_execute()``.
+
+.. code-block:: php
+
+    <?php
+    if (ORM::raw_execute('DROP TABLE my_table')) {
+        echo "Table dropped";
+    } else {
+        echo "Drop query failed";
+    }
+
+Selecting rows
+~~~~~~~~~~~~~~
+
+.. warning::
+
+    You really, should not be doing this, use Idiorm with ``raw_query()`` instead
+    where possible.
+
+Here is a simple query implemented using ``raw_execute()`` - note the call to 
+``ORM::get_last_statement()`` as ``raw_execute()`` returns a boolean as per the
+`PDOStatement::execute()`_ underneath.
+
+.. code-block:: php
+
+    <?php
+    $res = ORM::raw_execute('SHOW TABLES');
+    $statement = ORM::get_last_statement();
+    $rows = array();
+    while ($row = $statement->fetch(PDO::FETCH_ASSOC)) {
+        var_dump($row);
+    }
+
+It is also worth noting that ``$statement`` is a ``PDOStatement`` instance so calling
+its ``fetch()`` method is the same as if you had called against PDO without Idiorm.
+
+Getting the PDO instance
+''''''''''''''''''''''''
+
+.. warning::
+
+    By using this function you're dropping down to PHPs PDO directly. Idiorm
+    does not make any attempt to protect you from making errors when using this
+    method.
+
+    You're essentially just using Idiorm to manage the connection and configuration
+    when you implement against ``get_db()``.
+
+If none of the preceeding methods suit your purposes then you can also get direct
+access to the PDO instance underneath Idiorm using ``ORM::get_db()``. This will
+return a configured instance of `PDO`_.
+
+.. code-block:: php
+
+    <?php
+    $pdo = ORM::get_db();
+    foreach($pdo->query('SHOW TABLES') as $row) {
+        var_dump($row);

+Transactions
+============
+
+Idiorm doesn’t supply any extra methods to deal with transactions, but
+it’s very easy to use PDO’s built-in methods:
+
+.. code-block:: php
+
+    <?php
+    // Start a transaction
+    ORM::get_db()->beginTransaction();
+
+    // Commit a transaction
+    ORM::get_db()->commit();
+
+    // Roll back a transaction
+    ORM::get_db()->rollBack();
+
+For more details, see `the PDO documentation on Transactions`_.
