Mysql/python -- Committed Changes Not Appearing In Loop

Solution 1:

The default isolation level of InnoDB is REPEATABLE READ. This means that subsequent consistent SELECT statements will read the same snapshot established by the first within a transaction. Though you're opening and closing cursors, you're probably doing that inside a transaction and so you're reading the established snapshot over and over again. Either ROLLBACK or COMMIT to end the current transaction so that you can read values committed after the snapshot was taken.
