Thanks again, Olivier.
I'm trying with plain SQL commands just for convenience, it's my
first approach.
Now I'll try with my favourite interface, IB Objects. Maybe is
yours, also? If I have in trouble, sure I'll issue a question to the
IBO list.
Anyway, if someone knows a workaround through SQL syntax, please say
something.
Thanks,
Hugo.
