We have solved the problem (sort of) and caused another. The
database was registered incorrectly in IB Expert (using the
Interbase client dll and not FB client dll). Thanks for your help
and to Tim. The query select first... does now work in IB Expert,
but not from our delphi application. We are using the Interbase
components in Delphi, which I assume is the problem. Is there any
possible way to fix this?

The other problem we are facing now is that we cannot access the
same database from IB Expert and our delphi application (either run
or design time) at the same time. The error...
Unsuccessful execution caused by a system error that precludes
successful execution of subsequent statements.
I/O error for file "C:\DB.FDB".
Error while trying to open file.
The process cannot access the file because it is being used by
another process.

Thanks, Adele
