VbzCart/docs/procs/Upd Titles fr TitleIttyps

About

• Purpose: Updates some fields in Template:Vbzcart
• Input: Template:Vbzcart, grouped by ID_Title
• Output: Template:Vbzcart (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→Template:Vbzcart→Template:Vbzcart→Template:Vbzcart→this, so changed source from Template:Vbzcart to Template:Vbzcart/query.
