Hi Dmitriy, I considered just doing a string replacement, however this might be potentially dangerous because in theory a query might contain a question mark as part of a string or similar. Although I'm certain it would work for us at the moment, it looks like a problem waiting to happen. Doing a proper replacement (as ODBC probably does) most likely requires a full blown SQL parser...
