creditleaveid empid creditleavemonth creditedleaves 
1    21  March    1 

が

DELIMITER $$ 
CREATE EVENT creditleavemonth 
ON SCHEDULE EVERY '1' MONTH 
STARTS '2017-02-01 00:00:00' 
DO 
BEGIN 
CALL spAddCreditLeaves; 
END$$ 

DELIMITER ; 

ストアドプロシージャspAddCreditLeavesある

DELIMITER $$ 

USE `attendance`$$ 

DROP PROCEDURE IF EXISTS `spAddCreditLeaves`$$ 

CREATE DEFINER=`root`@`localhost` PROCEDURE `spAddCreditLeaves`() 
BEGIN 
INSERT INTO creditleaves(empid,creditleavemonth)SELECT empid,MONTHNAME(CURDATE())FROM empdetails; 
END$$ 

DELIMITER ;

Answer 1

私は自分の答えを持っています。それはすごくうまくいっています。

USE `attendance`$$ 

DROP PROCEDURE IF EXISTS `spAddCreditLeaves`$$ 

CREATE DEFINER=`root`@`localhost` PROCEDURE `spAddCreditLeaves`() 
BEGIN 
IF MONTHNAME(CURDATE())='January' 
THEN 
INSERT INTO creditleaves(empid,creditleavemonth,creditmonthyear,creditedleaves) SELECT empid,MONTHNAME(CURDATE()),YEAR(CURDATE()),creditedleaves+1 FROM creditleaves WHERE empid IN (SELECT empid FROM empdetails GROUP BY empid) AND creditedleaves IN(SELECT creditedleaves FROM creditleaves WHERE creditleavemonth=MONTHNAME((CURDATE()-INTERVAL 1 MONTH)) AND creditmonthyear=YEAR((CURDATE()-INTERVAL 1 YEAR))); 
ELSE 
INSERT INTO creditleaves(empid,creditleavemonth,creditmonthyear,creditedleaves) SELECT empid,MONTHNAME(CURDATE()),YEAR(CURDATE()),creditedleaves+1 FROM creditleaves WHERE empid IN (SELECT empid FROM empdetails GROUP BY empid) AND creditedleaves IN(SELECT creditedleaves FROM creditleaves WHERE creditleavemonth=MONTHNAME((CURDATE()-INTERVAL 1 MONTH)) AND creditmonthyear=YEAR(CURDATE())); 
END IF; 
END$$ 

DELIMITER ;
