Loop in MySql Stored Procedures

Hi. I am new to mysql but i have previous experience in oracle. I want to loop a selection and then insert the data into another table. Is there any way to do it in mysql? As per my research i found that i could loop using a variable but everytime i have to select inside the loop to get what i want. I want to achieve something like this in mysql:

DELIMITER //

CREATE PROCEDURE insert_data()
BEGIN
	for REC in (select data_1, data_2 from table_a)
	loop
		insert into table_b 
		values(rec.data_1,rec.data_2);
	end loop;
END

DELIMITER ;
