I know that (well, most of it anyway). That's why I estimated that the
performance loss there would be less than the performance loss caused by
a larger dataset being transferred via TCP/IP, even though the TCP/IP
connection is local.

Still, I'd like to keep the number of non-portable "utility objects" in
my database to a minimum, so I try to avoid SP:s. The application
currently supports both SQL Server and Firebird and I'd like to expand
that list rather than reduce it.

Thank you allthesame,
Kjell
