Okay, look, here's my question. If I issue and SQL request against a logical
and the logical is built with select/omit criteria, will the records
returned be filtered by the s/o criteria? 

I have always counted on this for query, but I don't know if SQL behaves the
same way. I would expect it to, since I might give access to a logical for
purposes of security.
