About
- Requires: Template:Vbzcart/query, Template:Vbzcart/query
- Used by: catalog building process (details to be documented)
- History:
- 2008-03-15 Building sequence completely rewritten, so presumably this query was created then
- 2008-04-02 convert blanks to nulls in b.ItOpt_Descr_part
- 2010-12-29 Added ID_Supplier because Template:Vbzcart now needs that field set.
- Fields:
- b.ItOpt_Descr_part apparently often comes up as "" rather than NULL, so we have to convert blanks to nulls before testing for null.
