我需要一些帮助来完成此触发器。我尝试过,但不知道怎么了。
这是代码:
delimiter $$
CREATE TRIGGER attendance_clock AFTER INSERT ON alldevicerecord
FOR EACH ROW
BEGIN
DECLARE check INT;
SET check= 1;
IF (check % 2 == 0) THEN
INSERT into designation(emp_id, clock_date, clock_in) VALUES (new.id, new.time, new.time);
check = check + 1;
ELSE
UPDATE designation SET clock_out = new.time WHERE emp_id = NEW.id;
check = check + 1;
END IF
END$$
delimiter ;
任何人都可以帮助我吗?
