About
- Input: cat_supp, _titles, _title_ittyps, cat_ittyps
- Output: _supplier_ittyps (delete/insert)
- Notes: Later we might refine this into a way to view unavailable suppliers as well... but that's very low priority, and it might be better to have a separate table for it anyway (keep "active" operations fast).
- History:
- 2010-11-10
- Added DROP PROCEDURE for easier maintenance.
- Created in database (procs were not ported from L48 to Rizzo) (why did this one work without any DELIMITER commands?).
- 2011-02-02
- Added WHERE tc.cntForSale>0 so it wouldn't count titles with nothing for sale (duh).
- Added AND (it.ID IS NOT NULL) -- input data evidently includes some rows where Item Type is NULL. This needs to be fixed.
- 2010-11-10
