Unfortunately, if you just change the query it won't work in Oracle. We're supporting both Oracle and Postgres with a single set of sources, so Oracle-specific and PG-specific inline queries are a no-no.
That's why we're waiting for the query dispatcher and query extractor work to be completed before plunging forward. As I mentioned a few posts earlier in this thread.
Please do a little RTFM'ing before making gadfly posts. We're happy to have you here but you're going to have to dig into the project a bit more before you help in a meaningful way.
