pg_field_table (no version information, might be only in CVS) pg_field_table -- Returns the name or oid of the tables field Descriptionmixed pg_field_table ( resource result, int field_number, bool oid_only )
pg_field_table() returns the name of the table that field
belongs to, or the table's oid if oid_only is TRUE.
Parameters
- result
PostgreSQL query result resource, returned by pg_query(),
pg_query_params() or pg_execute()
(among others).
- field_number
Field number, starting from 0.
- oid_only
By default the tables name that field belongs to is returned but
if oid_only is set to TRUE, then the
oid will instead be returned.
Return Values
On success either the fields table name or oid. Or, FALSE on failure.
Examples
Example 1. Getting table information about a field <?php
$dbconn = pg_connect("dbname=publisher") or die("Could not connect");
$res = pg_query($dbconn, "SELECT bar FROM foo");
echo pg_field_table($res, 0);
echo pg_field_table($res, 0, true);
$res = pg_query($dbconn, "SELECT version()");
var_dump(pg_field_table($res, 0));
?> |
The above example will output
something similar to: |
NotesNote:
Returning the oid is much faster than returning the table name because
fetching the table name requires a query to the database system table.
