PHP Bug Type: PDO related
Bug description: MySQL stored procedure doesn't return value when using
bindParam()
Description:
------------
I created a trivial stored procedure in MySQL (v5.0.17) that simply
returns an integer constant. If I call the procedure using a PDO statement
and binding a return value $stmt->bindParam(), I get nothing.
On the other hand, if I issue two SQL queries to implicitly obtain the
result, things are ok (see below). So something is broken with the way PDO
handles bindParam.
I am using the latest stable release of PHP (5.1.1), MySQL 5.0.17 and
mod_php for Apache 2.2
Reproduce code:
---------------
<?php
$DB = new PDO(...);
if($DB != NULL) {
$stmt = $DB->prepare(" CALL test_pdo(?)");
$stmt->bindParam(1, $return_value, PDO::PARAM_INT, 10);
$stmt->execute();
print "Procedure returned: $return_value \n";
//try instead plain SQL call
$DB->query("CALL test_pdo(@nn)");
$rows = $DB->query("SELECT @nn")->fetchAll();
print "SELECT returned: \n";
print_r($rows);
}
?>
And here's actual MySQL Stored procedure:
CREATE PROCEDURE test_pdo
(OUT Pout INTEGER)
BEGIN
SET Pout := 1912;
END
Expected result:
----------------
$return_value should have been set to "1912" and instead it's empty. The
stored procedure is working ok as the second call (in which i implicitly
obtain the output by making two SQL queries) returns the correct value
(see below).
Actual result:
--------------
Procedure returned:
SELECT returned:
Array ( [0] => Array ( [EMAIL PROTECTED] => 1912 [0] => 1912 ) )
