  Example query:

  SELECT ACC.ts_easeofworking
        , GOM.ts_easeofworking
        , ACC.ts_companytype 
        , GOM.ts_companytype [ts_companytype_multi_valued_string]
        , Splitter.ItemNumber
        , Splitter.Item
     FROM GlobalOptionsetMetadata GOM
  
    CROSS APPLY dbo.DelimitedSplit8k(GOM.ts_companytype,';') Splitter
  
     INNER JOIN account ACC
       ON ACC.ts_easeofworking = GOM.ts_easeofworking
        AND ACC.ts_companytype = Splitter.Item

  Basically, dbo.DelimitedSplit8k splits your string column into a virtual table based on the provided split-character

  Install it, and test it ( even if you do not understand it 100% )

  So it will  turn '123;456;78900' into

  ItemNumber  Item

  1                        123

  2                        456

  3                        78900

   

  As you may have understood by now, it certainly is not the most optimal way to store relationship data in a csv column.

  Start small, see what it does and where it gets you.

  Then build on that.

  p.s. I've been off the grid for a couple of days .... time of the year
