** '''2009-04-12''' No longer caching stock-quantity fields in cat_items, so had to pull in v_stk_items_remaining; removing cntStkForSale until I find out what it is needed for
** '''2009-04-12''' No longer caching stock-quantity fields in cat_items, so had to pull in <s>v_stk_items_remaining</s> qryCat_Items_Stock; removing cntStkForSale until I find out what it is needed for
** '''2009-11-29''' Adding ID_Supplier for more efficient coding (see {{vbzcart/query|qryItTypsDepts_ItTyps}})
*** Also removing commented-out cntStkForSale
* '''Notes''':
** This is essentially the same query as {{vbzcart/query|qryTitles_ItTyps_grpItems}} but grouped by ID_Dept (and ID_ItTyp) instead of ID_Title (and ID_ItTyp).
