Question

我有两个名为＆＃34; case＆＃34;和出勤分别有四列：

cases-
 id  empid     reaction    date_t
 1   EMP12654 interested   2017-09-22

 attendance-

id empid    logintime logouttime   date_t      flag  workinghours call_att
1  EMP12654 00:14:49   05:14:49    2017-09-18  set      6          1

我想要做的是在案例表上创建一个触发器来更新考勤表的call_att列和案例表的反应栏中的条目数，这是我到目前为止所尝试的

    CREATE DEFINER=`root`@`localhost` TRIGGER `number_call` 
AFTER INSERT ON `cases` FOR EACH ROW 
BEGIN UPDATE attendance set call_att=call_att +1 
WHERE empid=new.empid AND date_t=new.date_t; END

但这似乎不起作用。我对触发器很陌生。

Answer 1

试试这个

CREATE TRIGGER number_call 
    AFTER INSERT ON cases
    FOR EACH ROW 
BEGIN
UPDATE attendance set call_att=(select count(*) from cases where empid=NEW.empid )
date_t=NEW.date_t;
END

在MySQL中插入后更新其他表列
