I always wonder if the query builder could not cast those automatically, but I guess it cause we don't have type information on the php side for the columns and sqlite considering everything as a string 🙈

The QBMapper usually would do that, but is not used here. A pitfall to be aware about. Having this automatic with the DB abstraction (based on migration?) would be fancy indeed.
