Mysql创建存储过程时出现ERROR 1064错误

Posted 2021-05-25 PoetryAndTheDistance

ERROR 1064 (42000):ERROR 1064 (42000): 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 'DECLARE i INT DEFAULT 0' at line 1

 

创建存储过程时，报错了。

DROP PROCEDURE IF EXISTS GameServerMergePro;  
CREATE PROCEDURE `GameServerMergePro` (  
    IN dbSchema VARCHAR(50) character set utf8,  
    IN sName VARCHAR(50) character set utf8,  
    OUT error_code INT  
)   
begin  
DECLARE ddddi INT DEFAULT 0;  
end;  

 

琢磨了半天，原来Mysql解释器一遇到;号时就结束，回车以后就执行了。但是现在并不希望Mysql这么做，因为存储过程中可能 包含很多分号的语句，所以怎么办了，很简单Mysql给我们提供了delimiter关键字，delimiter作用就是把;分号替换成指定的符号，比如//或$$。当再出现//或$$时，Mysql解释器才会执行命令。

 

脚本改成下面之后，执行就不会报错了。

DELIMITER //   
DROP PROCEDURE IF EXISTS GameServerMergePro;  
CREATE PROCEDURE `GameServerMergePro` (  
    IN dbSchema VARCHAR(50) character set utf8,  
    IN sName VARCHAR(50) character set utf8,  
    OUT error_code INT  
)   
begin  
DECLARE ddddi INT DEFAULT 0;  
end;  
//  
DELIMITER ;
