數據庫 - Mysql的存儲過程真的是個坑！求助下面的存儲過程哪里錯啦，實在是找不到哪里的問題了。

問題描述

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：獲取當前年度和季度select period,tyear into p_period,p_tYear from tm_checkmain where id = 95 LIMIT 1;-- 2：如果季度是1，則上年得分為0，否則要計算 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

將IF判斷注釋掉，則通過，否則則報錯。

請教高手，IF判斷根本沒有錯誤呀。
