I haven't had a chance to look at the code myself, but here is the exception/traceback:

It looks like since I am using tsql, LIMIT is not supported. I think it is the same as if I used TOP instead.

When I have a chance I'll see if I can pull down the code, make some sort of detection, and rewrite the queries. I will submit a PR when finished.

There are already some ifs for SQLite in place (like this), you can extend it in the same way I think.
