About

  • Purpose: fills Template:Vbzcart.
  • Input: Template:Vbzcart, Template:Vbzcart, Template:Vbzcart/query
  • Output: Template:Vbzcart (replace)
  • History:
    • 2007-09-20
      • Removed "WHERE i.isForSale" because this prevented the availability of discontinued items from being properly zeroed out
      • Added cntInStock calculation; see table schema
    • 2010-11-10
      • Added DROP PROCEDURE for easier maintenance.
      • Actually created in database (procs did not get ported from L48 to Rizzo).
    • 2010-11-13 Source field qtyInStock was renamed to qtyIn_Stk some time ago...
      • Added cntInPrint, cntLines
      • Added (ID_Dept IS NOT NULL) AND (ID_ItTyp IS NOT NULL) to prevent those fields being null (not allowed in target table)
    • 2011-01-23 fetching Stock data from Template:Vbzcart/query instead of relying on Template:Vbzcart to be current
  • Notes:
    • This is a revised version which combines two earlier procedures.
    • I had a note that "the ID_Dept field is informational, not a grouping", but I don't remember what that meant and it doesn't make sense.
