Answer: No, it is not possible, because InterBase/Firebird do not support such SQL commands.
FIBPlus has taken the headache out of this project. When I got the current contract, FIBPlus was included on the work computer from the client. I quickly found it easier to use and more powerful than any other Firebird component suite I had tested. When I ran into a problem setting up a persistent calculated field, the tech support people saved the day. I would also add that I tested Zeos, IBX, DBGo, UIB, and other FBconnectors. FIBPlus outperformed all of them, and FIBPlus was run on an older machine than the others were. That was most impressive.>>
