SELECT CONCAT(DATE_FORMAT((CURDATE()), '%Y'),'-01') AS date UNION

SELECT CONCAT(DATE_FORMAT((CURDATE()), '%Y'),'-02') AS date UNION

SELECT CONCAT(DATE_FORMAT((CURDATE()), '%Y'),'-03') AS date UNION

SELECT CONCAT(DATE_FORMAT((CURDATE()), '%Y'),'-04') AS date UNION

SELECT CONCAT(DATE_FORMAT((CURDATE()), '%Y'),'-05') AS date UNION
