I have always used Dialect 3. Linux Firebird, Windows Firebird, and
Windows Interbase servers were all tested on the same *.gdb file and
the same Delphi executable application. Interbase worked fine without
SQLDataSet persistent fields, Firebird would not work without them.
Actually, the pre-release candidate version of Linux Firebird did
work, but after I downloaded and installed the new Linux Firebird 1.0
I started receiving errors from RefreshRecord.
