Maybe I'm missing something obvious, but frx reports will work against any cursor you point them at. Why not just use remote views against the sql, massage the data however you like, parameterize, whatever?

Though a good deal is too strange to be believed, nothing is too strange to have happened.
- Thomas Hardy

Half the harm that is done in this world is due to people who want to feel important. They don't mean to do harm-- but the harm does not interest them. Or they do not see it, or they justify it because they are absorbed in the endless struggle to think well of themselves.

-- T. S. Eliot
Democracy is two wolves and a sheep voting on what to have for lunch.
Liberty is a well-armed sheep contesting the vote.

Pardon him, Theodotus. He is a barbarian, and thinks that the customs of his tribe and island are the laws of nature.
