database queries

[Oliver Bronkalla]

I'm trying to find out, whether there is a need for
database queries which calls userdefined functions in the
condition part to evaluate whether a data record satisfies the
query or not.

Is there anybody, who can help me whith a few useful
(possible complex) examples of such queries?


Thanks in advance,
Oliver Bronkalla
