简单存储过程参数导致未知错误

Question

It's a simple procedure, I just cannot for the life of me find the error in this syntax. I've learned at other posts and couldn't find a working solution.

CREATE PROCEDURE cooldownUpdate @command VARCHAR(18)
AS
UPDATE `mention_cooldowns` SET cooldown = 'true' WHERE command = @command
GO;

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' @command VARCHAR(18) AS UPDATE mention_cooldowns SET cooldown = 'true' WHERE c ' at line 1

Answer 1

Firstly, you have to set a delimiter while creating stored procedure. Also, you have to define whether the parameter is for IN or OUT and finally you have to wrap your queries inside BEGIN and END for best practice.

Please check below for creating stored procedure.

DELIMITER //

CREATE PROCEDURE cooldownUpdate(IN pCommand VARCHAR(18))
BEGIN
    UPDATE `mention_cooldowns` SET cooldown = 'true' WHERE command = pCommand;
END //

DELIMITER ;
