If I have (2) tables. Like
GROUP , CODE GRP1, AA GRP1, AB GRP1, AC GRP2, BA GRP2, BB GRP2, BC And; USER , UCODE ME, AA ME, AC YOU, AA What's the best way to query to find out if "ME" has all codes in either of the groups? In other words, I want to know if I have all (3) CODEs required for GRP1, and all (3) CODEs required for GRP2?
