Hi all,
Yesterday I played with PDO and I ran into an unexpected behaviour.
In the following code, statement 2 is never executed because of a out of
sync warning.
But if you have exceptions enabled there is no exception thrown and you
wonder about the result.
Should a new statement not override an old statement?
Why are there statement objects if I could only execute one statement?
Is this a db driver specific issue or because it's not implemented yet?
For testing I used PHP 5.1.0b2.
<?php
$pdo = new PDO('mysql:dbname=db;host=localhost', 'user', 'password');
$pdo->setAttribute(PDO_ATTR_ERRMODE, PDO_ERRMODE_WARNING); # Try in
exception mode, too
$stmt_1 = $pdo->prepare('SELECT x FROM table');
$stmt_1->execute();
$stmt_2 = $pdo->prepare('SELECT y FROM table');
$stmt_2->execute();
// Returns nothing !!!
print("Statement2: \n");
while ($row = $stmt_2->fetch(PDO_FETCH_ASSOC)) print_r($row);
print("Statement1: \n");
while ($row = $stmt_1->fetch(PDO_FETCH_ASSOC)) print_r($row);
?>
