Mysql Stored Procedure If-else statement not working

I set up mysql stored procedure. I have problem with if-else statement . It seem if else not work. Everyone have any idea. I want to check if state is 0 update new state.

CREATE DEFINER=`homestead`@`%` PROCEDURE `insertLoginLog`()
BEGIN
    DECLARE errno INT;
    DECLARE state INT;
    DECLARE EXIT HANDLER FOR SQLEXCEPTION
    BEGIN
        SELECT state INTO state FROM stored_procedure_state WHERE stored_procedure_state.name = 'insertLoginLog';
        IF(state = 0) THEN
        UPDATE stored_procedure_state SET state = 1 WHERE stored_procedure_state.name = 'insertLoginLog';
        END IF;
    END;
END
