RE: One more: rowcounts with DODS standalone!

Ok!

I understand now that the method works as a switch
modifying the SQL statement.
I looked a bit at the source code of the Query classes
generated and I get the impression that the caching
mechanism isn't involved. Will the result still be
cached?

Thanks for your help!

Axel
