By the way, what do you say to Steve's claim that T-SQL is a performance killer?

over the wire, what other tasks the server might be performing when
you ask it to call the function etc, I think I am not going to worry
about it, barring Steve coming up with something I have overlooked.

Since Steve hasn't yet replied to this, I thought I might insert a quote of his original assurtion to see if this helps calrify his point:

Steve,

Thank you for the reply.

In fact, I expressed my question badly -- I'm really interested in moving the functions to the back-end, so your comments on T-SQL are
most relevant to me. Is T-SQL really that slow? Suppose I choose
Oracle

T-SQL is not slow in general, however scalar functions really are that slow. It basically means you don't use scalar functions much,

instead; does PL-SQL have the required capabilities, and is it
faster than T-SQL?


PL-SQL does have the capabilities, and its scalar function
performance is great, but Access works slightly better with the MS
SQL Server back-end, and
you have to make sure your ODBC settings are just right, for
PostgreSQL to work correctly with Access on the front-end.
