Examples
Example #1 A PDO::pgsqlLOBUnlink() example
This example unlinks a large object from the database prior to deleting
the row that references it from the blobs table we've been using in
our PDO::pgsqlLOBCreate() and
PDO::pgsqlLOBOpen() examples.
<?php $db = new PDO('pgsql:dbname=test host=localhost', $user, $pass); $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $db->beginTransaction(); $db->pgsqlLOBUnlink($oid); $stmt = $db->prepare("DELETE FROM BLOBS where ident = ?"); $stmt->execute(array($some_id)); $db->commit(); ?>
