About

Purpose: Updates some fields in _titles
Input: _title_ittyps, grouped by ID_Title
Output: _titles (update)
History:
- 2010-11-10
  - Added DROP PROCEDURE for easier maintenance.
  - Created in database (procs were not ported from L48 to Rizzo).
- 2011-12-24 this was in a recursive loop: this→_titles→Upd_TitleIttyps_fr_Titles→_title_ittyps→this, so changed source from _title_ittyps to

REDIRECT Template:l/vc/query.

SQL

<mysql>DROP PROCEDURE IF EXISTS Upd_Titles_fr_TitleIttyps; CREATE PROCEDURE Upd_Titles_fr_TitleIttyps()

   SELECT
     ID_Title,
     SUM(ti.cntForSale) AS cntForSale,
     SUM(ti.cntInPrint) AS cntInPrint,
     SUM(ti.qtyForSale) AS qtyInStock
    FROM qryCat_Titles_Item_stats AS ti GROUP BY ID_Title
   ) AS ti ON ti.ID_Title=t.ID
   SET
     t.cntForSale = ti.cntForSale,
     t.cntInPrint = ti.cntInPrint,
     t.qtyInStock = ti.qtyInStock;</mysql>
