Add extra Query method types

Add extra Query method types.

I passed through each of the Query methods without return types and checked the docs for each one of them, I added the types for the ones that don't modify the return columns, so the same _Q query (or _T type) can be used.

There's a chance that some of the methods I left un-annotated could actually be safely annotated, but I'm not really sure, so I decided to leave them as they are.
