# 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.
