More than one cursor in procedure Mysql

It is possible however you have to work in a different way the loop, not just checking the done variable, because when the first cursor is executed it will not execute the second one, then we will work another way to see if it is complete or not verifies how many records to go through and we set a counter and how much to go through all the lines let the variables done1 and done2, thus:

begin

    DECLARE done2 INT DEFAULT 0;
