About
- Purpose: Updates some fields in _titles
- Input:
- REDIRECT Template:l/vc/query, 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 qryCat_Titles_Item_stats.
- 2010-11-10
