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);
    set `check`  = `check` + 1;
  ELSE
    UPDATE designation SET clock_out = new.time WHERE emp_id = NEW.id;
    set `check`  = `check` + 1;
  END IF;
END;
