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

Opis

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.

Parametry

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.

Zwracane wartości

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

Przykłady

Przykład 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));
?>

Powyższy przykład wyświetli coś podobnego do:

foo
14379580

bool(false)

Notatki

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