Mysql的存储过程真的是个坑！求助下面的存储过程哪里错啦，实在是找不到哪里的问题了。

Question

BEGIN

declare step1,step2 varchar(50);
declare p_tar_code varchar(10);
DECLARE p_tYear,p_period int;
DECLARE p_centAll,p_up_comCent decimal(5,2);

-- 1：获取当前年度和季度
select period,tyear into p_period,p_tYear from tm_checkmain where id = 95 LIMIT 1;

-- 2：如果季度是1，则上年得分为0，否则要计算
 if period = 21 then 
     set p_up_comCent = 0;
 end if
 

select tar_code into p_tar_code from tm_checkdetails where id = 95 LIMIT 1;

 set str = p_tar_code;

END

将IF判断注释掉，则通过，否则则报错。

请教高手，IF判断根本没有错误呀。
