Ok, ok, it seems it must be my problem...
:-( sorry.

I'm trying with both ISQL (from IBConsole) and
a Delphi 5/6 application using Interbase Express
controls.

Maybe I have a wrong version of Interbase.
I'll try again downloading from Borland's
opensource page. Or I'll try Firebird.

I was even more confused after reading the
article I refered before at Borland's
site.

Thanks.
