OK, I've spent about an hour trying to figure this out. SQL does not like the following statement: DELETE FROM PODTL WHERE (VNDNR, WEEKX, DIGIT) NOT IN (SELECT (VNDNR, WEEKX, DIGIT) FROM POHDR); I did this identical thing a half dozen times yesterday *EXCEPT* there was only one field name to match on, not 3. I've looked at manuals and googled. I've tried with/without parens, with/without commas to no avail. All the examples I find do it on only one field. What's wrong with the syntax?
