pg_field_table

(no version information, might be only in CVS)

pg_field_table -- Returns the name or oid of the tables field

Description

mixed 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($res0);
echo 
pg_field_table($res0true);

$res pg_query($dbconn"SELECT version()");
var_dump(pg_field_table($res0));
?>

The above example will output something similar to:

foo
14379580

bool(false)

Notes

Note: Returning the oid is much faster than returning the table name because fetching the table name requires a query to the database system table.
