RE: SQL delete not in related table

Well I just learn more all the time.  The following worked:

DELETE FROM PODTL WHERE CONCAT(VNDNR, CONCAT(WEEKX, DIGIT)) 
          NOT IN SELECT CONCAT(VNDNR, CONCAT(WEEKX, DIGIT))      
          FROM POHDR);                                     

I discovered that you can only CONCAT 2 fields at a time.  It seems
interesting that as flexible and powerful is starting to appear to me, that
it would have such a restriction.  Guess RPG isn't the only language with
weird ones. <g>
