Yes indeed!  First, let me say that I am not arguing -- your reply was 
incredibly helpful in understanding the situation, and I thank you very 
much!

This was my situation.  I originally ran my SELECT specifying only the 
PF, but the optimiser apparently preferred one of the DDS logicals.  I 
verified that this was the case when I copied the PF to a temporary 
library and ran the SELECT over that (there were no LFs over it there) 
and the query ran.

Page 160 of the V5R4 SQL Reference does not mention LF with select/omit 
as the restriction.

I did verify that your explanation is more accurate.  I chose a PF 
having no LF with S/O and it works as expected.

Thank you as always for your help Birgitta!  I need to go spend some 
time in the DB2 manual and look at all the options in QAQQINI.
Tschuess!
