Question

I have this Stored Procedure. When I execute it in my PhpMyAdmin on Wamp, it says it executed and everything. When I try to use it in a query, it says the function is not there. What am I doing wrong?

DELIMITER //

CREATE PROCEDURE `sql_level`(IN exp INT)
BEGIN
    SELECT id
    FROM `levels`
    WHERE experience <= exp DESC LIMIT 1;
      id = id-1;
END //

DELIMITER ;

Here is the Query I’m trying to run.

$id = 1;
if($stmt->prepare("SELECT sql_level(attack) FROM `users` WHERE id = ?")) { 
$stmt->bind_param('i',$id); 
$stmt->execute(); 
$stmt->bind_result($attack); 
$stmt->fetch(); echo "<h1 align='center'>".$attack."</h1>";  } 
else { die($stmt->error); }

Thanks.

DELIMITER |
CREATE FUNCTION `sql_level`(exp INT)
RETURNS INT
DETERMINISTIC
BEGIN
DECLARE ReturnId INT;

SELECT id-1 INTO ReturnId
FROM `levels`
WHERE experience <= exp;

RETURN ReturnId;
END;

This is what I ended up using to make it work. Thanks! Hope this helps someone!
