It's not an INOUT parameter though.

Hi,

I'm calling a MySQL Stored Procedure via PDO (PHP 5.2.3)

$stmt = $dbh->prepare('CALL forum_post(?, ?, ?, ?, ?, @status, @thread_id, 
@message_id)');

At the moment in order to get the values of status, thread_id and
message_id I need to issue a second query:

$sql = "SELECT @status AS status, @thread_id AS thread_id, @message_id AS 
message_id";

and then foreach my way through it:

foreach ($dbh->query($sql) as $row)
{
$status = $row['status'];
$thread_id = $row['thread_id'];
$message_id = $row['message_id'];
}

Which seems a bit insane.. is there no way to do a bindValue at the
same time as I do my bindParams?

Now I write this I really can't remember why I am even putting that
second query into a foreach loop, even so it's still a step I'd like
to remove entirely if possible?

Cheers,

Rich

Example 1716. Calling a stored procedure with an input/output parameter
prepare("CALL sp_takes_string_returns_string(?)");
$value = 'hello';
$stmt->bindParam(1, $value, PDO::PARAM_STR|PDO::PARAM_INPUT_OUTPUT, 4000);

// call the stored procedure
$stmt->execute();

print "procedure returned $value\n";
?>
