Here's a mysql stored procedure to loop through the results of a select query that returns ids and performs an additional operation on each id.

	DROP PROCEDURE IF EXISTS migrateById;
	DELIMITER $$

	CREATE PROCEDURE migrateById()
	BEGIN
	DECLARE done INT DEFAULT FALSE;
	DECLARE _post_id INT;
	DECLARE migrate_ids CURSOR FOR

	# modify the select statement to returns IDs, which will be assigned the variable `_post_id`
