Re: Fw: Difference between Select and Omit in LF

["Michael Naughton" <michael_naughton@xxxxxxxxxxxx>]

Peter,

The select will only be equivalent to the omit if one is ANDed and the
other is ORed, i.e.:

SELECT (X AND Y)
is equivalent to
OMIT (NOT X OR NOT Y)

and

SELECT (X OR Y)
is equivalent to
OMIT (NOT X AND NOT Y)

so first you have to figure out which pair will give you the results
you're looking for, and then set up your logicals accordingly.

hth,

PS: the above is basic Boolean algebra . . . .
