pg_field_table

(PHP 5 >= 5.2.0)

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($res, 0);
echo pg_field_table($res, 0, true);

$res = pg_query($dbconn, "SELECT version()");
var_dump(pg_field_table($res, 0));
?>

The above example will output something similar to:

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.
