mySQL怎么读取数据库配置文件路径

mysql中获取数据库配置文件路径的方法1首先，在命令行中，启动MySQL服务；service mysql start　　　2MySQL服务启动后，输入用户名和密码，登录mysql数据库；mysql -u root -p3

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 ROW

begin

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;
