VbzCart/docs/procs/Upd Depts fr DeptIttyps

About

• Purpose: Updates some fields in Template:Vbzcart after that has been filled in by Template:Vbzcart
• Input: Template:Vbzcart/query (group by ID_Dept)
• 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 long recursive loop: this → Template:Vbzcart → Template:Vbzcart → Template:Vbzcart → Template:Vbzcart → Template:Vbzcart → Template:Vbzcart → Template:Vbzcart → this, so replacing source Template:Vbzcart with Template:Vbzcart/query
