Örnek 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));
?>
Yukarıdaki örnek şuna benzer bir çıktı üretir:
foo 14379580 bool(false)
Bilginize:
Returning the oid is much faster than returning the table name because fetching the table name requires a query to the database system table.
