sql_language thread: writing a DISTINCT statement while also pulling other field data from that sort.

How are you deciding which row of the data you want for each product - for
instance for Toilet Paper C you have 3 different Ply values?
If you don't care & just wanted the first entry for each GenericProductName,
you could use something like...
SELECT * FROM ProdCat
WHERE ID IN (SELECT FIRST(ID) AS ID FROM ProdCat GROUP BY
GenericProductName)
ORDER BY GenericProductName DESC;
HTH,
