Binary cursors works just fine with JDBC. I can retrieve my binaries without any problem, and it's very very fast. Now, canyou assure me that it isn't converted into a String at some point? (I doubt it.)

I guess I can execute several queries in a row withdeclare and fetch, but will it send me the correct bytes?

I can retrieve the type just fine with the standard method,but the results of getBytes is altered. getString shows just the right thing, but I need the binary. I looked at thesource of the driver, and I still don't know exactly what I'm supposed to do. It seems to me that the QueryExecutor isable to fetch a binary tuple, but I don't know how to request one. > > > > > >Performance is my main problem, so I would like a fast solution.
