/**mySql中是否能有SQLserver的@@error变量呢，或者如c#中的try catch语法呢。答案是肯定的，实例代码如下：**/CodeDROP PROCEDURE IF EXISTS sp_call_jobs;CREATE PROCEDURE sp_call_jobs() NOT DETERMINISTIC SQL SECURITY DEFINER COMMENT ''BEGINdeclare _row,_err,_count int default 0;DECLARE CONTINUE HANDLER FOR SQLEXCEPTION,SQLWARNING,NOT FOUND set _err=1;while _row<3 DO START TRANSACTION; insert into t1(cond_val)values(null); COMMIT; if _err=1 then set _count=_count+1; end if; set _row=_row+1;end while;select _count;END; /**语句：DECLARE CONTINUE HANDLER FOR SQLEXCEPTION,SQLWARNING,NOT FOUND set _err=1;作用是当遇到SQLEXCEPTION,SQLWARNING,NOT FOUND 错误时，设置_err=1并执行CONTINUE操作，即继续执行后面的语句。这就与c＃中的try catch语法很像。而且在执行可能出错的语句的时候我们用事务语句：START TRANSACTION; …… COMMIT; 可以保证完整性。**/
