    @LearnatKnowstar Thanks for sharing such an amazing method of pivoting rows into columns but i have a question here , what if we want to execute similar operation with columns to rows then how it would be possible as columns name are not stored anywhere which can be called in pivot function. Please advise.

    • @LearnatKnowstar
      @LearnatKnowstar  3 ปีที่แล้ว +1

      You need to try alternate approach.
      SET @cols = STUFF((SELECT distinct ',' + QUOTENAME(c.Name)
      FROM dbo.Empl1 c
      FOR XML PATH(''), TYPE
      ).value('.', 'NVARCHAR(MAX)')
      ,1,1,'')

      You can try printing @sql text and check for any syntax errors. It could be due to missing spaces around the @col values that you have inserted.
