Re: SQL questions???

Elton,

I'm not sure I completely understand what you want but I've used INTERSECT to do similar things, i.e.:

  ( SELECT * FROM Table1 WHERE CODE1 NOT IN ( '1', '2','3') )   INTERSECT
  ( SELECT * FROM Table1 WHERE CODE2 IN ('A', 'B', 'C') ) ;

This will give you all the rows in Table1 where CODE1 is NOT 1,2 or 3 and CODE2 is A,B or C.

If you didn't want the rows CODE2 equal to A,B,C use MINUS instead of INTERSECT. Just my 2 cents worth.

Good Luck,
Hank Talbot
