# pg_field_table

(no version information, might be only in CVS)

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

## Descrição

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`.

## Parâmetros

`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.

## Valores de retornado

On success either the fields table name or oid. Or, `FALSE` on failure.

## Exemplos

Exemplo 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)); ?>`
O exemplo acima irá imprimir algo similar a:
    foo
    14379580

    bool(false)

## Notas

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