mysql - 这个存储过程代码有什么问题？

Question

下面的代码给出了许多与分号相关的错误。我是 MySql 的新手，所以一无所知。

CREATE PROCEDURE `sp_get_orderbystatus`(p_status_id int)

BEGIN
declare v int;
if(p_status_id = 1) then
begin
    set v = 1;
end;
end if;

END

Answer 1

如果您尝试在 mysql cli 中执行此操作，则似乎需要更改 DELIMITER。

DELIMITER // -- change the delimiter to '//' 

CREATE PROCEDURE `sp_get_orderbystatus`(p_status_id int)
    DECLARE v INT;
    -- the rest of the code of your procedure
END//

DELIMITER ; -- change it back to ';'

Defining Stored Programs
If you use the mysql client program to define a stored program containing semicolon characters, a problem arises. By default, mysql itself recognizes the semicolon as a statement delimiter, so you must redefine the delimiter temporarily to cause mysql to pass the entire stored program definition to the server.
