It doesn’t actually do the connectivity bit, it just makes the calls to other dbcs look the same (of course doesn’t fix the different dialects of SQL, except for parameter syntax).  It offers prepared queries and query parameters, which, as far as I can tell, LuaDBI and LuaSQL don’t.  On the other hand, it’s so not finished that it’s barely started.

Precisely because SQL dialects are different, I gave up trying to
treat them the same, and just use the client for the database at hand.
If you do try and have a common subset, it just means you miss out on
the cool advanced features.

It's probably nice going all the way and making every database work
the same, but IMO that's a multi-year project,
The existing implementations being JDBC and sqlalchemy; and they still
are missing things.

So, I probably would not use your library unless you put quite a lot
of effort in;
This would include things like non-blocking forms, and consistent
encodings (e.g. MySQL you need utf8mb4).
