Answer 1

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;
