mysql中调试触发器的方法
具体调试方法如下：
CREATE DEFINER=`root`@`%` TRIGGER `t_afterinsert_to_summary` AFTER INSERT ON `a` FOR EACH ROWbegin
declare v1 VARCHAR( 20 );
declare v2 VARCHAR( 20 );
declare done int default 0;
DECLARE mob VARCHAR ( 20 );
DECLARE content VARCHAR ( 500 );
DECLARE node_ip VARCHAR ( 20 );
DECLARE mobile_list CURSOR FOR SELECT mobile FROM c WHERE c.c = new.c1;
declare continue handler for not FOUND set done = 1; /*done = true;亦可*/
insert into t (x,cc) VALUES( new.c1, 'topfirest0');-------人为插入作业点
IF ( new.c1 = 0 ) THEN
insert into t (x,cc) VALUES( new.c1, 'firest1');-------人为插入作业点
select b into v1 from b where b.a=new.c1;
set v2=new.c1;
insert into t (x,cc) VALUES( new.c1, 'firest2');-------人为插入作业点
SET content = CONCAT( 'abcabcabc', '[', v2, ']', 'dede', v2,'ccddddd' );
insert into t (x,cc) VALUES( new.c1, 'firest3');-------人为插入作业点
insert into t (x,cc) VALUES( new.c1, 'firest4');-------人为插入作业点
OPEN mobile_list;-- 将游标中的值赋值给变量，要注意sql结果列的顺序
REPEAT
FETCH mobile_list INTO mob;-- while循环
if not done then
insert into t (x,cc) VALUES( new.c1, 'firest5');-------人为插入作业点
INSERT INTO t (x,cc) VALUES( v2, content);
end if;
-- 关闭游标
until done end repeat;
CLOSE mobile_list;
END IF;
end;
