In some cases you may wish to know which table a particular tuple
|
||||
originated from. There is a system attribute called
|
||||
<quote>TABLEOID</quote> in each table which can tell you the
|
||||
originating table:
|
||||
|
||||
<programlisting>
|
||||
SELECT c.tableoid, c.name, c.altitude
|
||||
FROM cities c
|
||||
WHERE c.altitude > 500;
|
||||
</programlisting>
|
||||
|
||||
which returns:
|
||||
|
||||
<programlisting>
|
||||
+---------+----------+----------+
|
||||
|tableoid |name | altitude |
|
||||
+---------+----------+----------+

|
||||
</programlisting>
|
||||
|
||||
If you do a join with pg_class you can see the actual table name:
|
||||
|
||||
<programlisting>
|
||||
SELECT p.relname, c.name, c.altitude
|
||||
FROM cities c, pg_class p
|
||||
WHERE c.altitude > 500 and c.tableoid = p.oid;
|
||||
</programlisting>
|

which returns:
