Re: How can I create null value from function call with no results?

Hi David,
Thanks for the feedback. I've actually tried to do what you've suggested,
but I always found myself unable to do the check for empty result for query
in an elegant way.
That is, I end up thinking about creating a temp table to put the query
results in (which can be > 1), then check if the temp table is empty and
return Null if that is the case.

Your response reads as if there is a more elegant way of doing this, could
you write down a dummy version of the alternative to return query you're
suggesting?

Kind regards
Seref

Ps: sorry for the double post David
