'Select' and 'insert into' multiple rows by a My Sql event - mysql

Question

I need to write a MySql Event to select some values from a table under some conditions and put those values in a second table. By the select statement. I get multiple rows, so I need to store data in the second table as a batch. How can I achieve this? I wrote an event to select one row. But what I need to do is select multiple rows and store as a batch.
The event I wrote is as below.
DELIMITER $$
CREATE EVENT salary_add
ON SCHEDULE EVERY 24 HOUR
DO
BEGIN
DECLARE month_end DATETIME;
DECLARE today DATETIME;
DECLARE reg_id VARCHAR(6);
DECLARE sal INT(8);
SET month_end = LAST_DAY(DATE(NOW()));
SET today = DATE(NOW());
IF month_end=today THEN
SELECT register_id,salary INTO reg_id,sal FROM employees
WHERE status ='1' LIMIT 1;
INSERT INTO tbl_salary (register_id,amount,salary_date,status) VALUES (reg_id,sal,today,'0');
END IF;
END $$
DELIMITER ;

Answer 1

You can insert selected rows into the target table at once. For example:
DELIMITER $$
CREATE EVENT salary_add
ON SCHEDULE EVERY 24 HOUR
DO
BEGIN
DECLARE month_end DATETIME;
SET month_end = LAST_DAY(CURDATE());
IF month_end=CURDATE() THEN
INSERT INTO tbl_salary (register_id, amount, salary_date, status)
SELECT register_id,
salary,
CURDATE(),
'0'
FROM employees
WHERE status ='1'
END IF;
END $$
DELIMITER ;
