我需要一些帮助来完成这个触发器我尝试但我不知道有什么问题:(我正在使用wampserver phpmysql ,,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;
