Thanks for your response. I really don't mean to push the issue, I'm just afraid that you misunderstood my question. In terms of existing providers, if I need to do, say, a DISTINCT query, I would have to either load the table into my own provider/SQLite DB and do it there by executing an arbitrary SQLite query, or use a content provider query and operate on the cursor manually. Both approaches are not as efficient as allowing us to directly do the distinct query to the provider itself. I just have a hard time understanding why there aren't overloaded query methods that allow for certain arguments, as there are with the SQLite packages (e.g. having a boolean for DISTINCT).
UNLESS you're saying that we can actually extend the functionality for existing providers and implement the query ourselves? If that's the case, that would be great, but I don't see how to do that from looking at the API spec...
