Display each DISTINCT Field Value only once using loop

Question

SELECT listTitle, listLength, listCmt, listDt, mBCFName, mBCLName, moAmt, moDtOff
FROM User U, Listing L, Merchant M, MerchantOffer MO
WHERE U.uID = L.uID
and L.listID =         


        

Answer 1

This is not that easy - the question is what to show for the other field (for example the "mBCFName" field - "Amanda" OR "John")?

use the "Group by" SQL statement and then define the rules (max,min,avg, GROUP_CONCAT ...) to select the other rows - Example:

SELECT listTitle, min(listLength), min(listCmt), min(listDt), GROUP_CONCAT(mBCFName), min(mBCLName), min(moAmt), min(moDtOff)
FROM User U, Listing L, Merchant M, MerchantOffer MO
WHERE U.uID = L.uID
  and L.listID = MO.listID
  and M.mID = MO.mId
GROUP BY listTitle
ORDER BY listDt DESC;
