Did you know that you can probably change your GROUP BY clause to use a
column ref, rather than repeating the CASE statement:
GROUP BY gmmid, gmmname, divid, divname, feddept, deptname, fedvend,
vendor_name, masterid, master_desc, pageid, oz_description, 13,
price_original, price_owned_retail, cur_price,
oz_color, oz_size,
pageflag, itemnumber, mkd_status, option4_flag
Doesn't help performance, but does help clarity :)
