In that case, following is much simpler: DECLARE @T AS TABLE ( pk integer PRIMARY KEY , col1 integer NULL , col2 integer NULL , col3 integer NULL , col4 integer NULL ); INSERT @T VALUES (1, 4, 3, 2, 1), (2, 5, NULL , 7, 8); SELECT MAX (f.x) AS Greatest , case MAX (f.x) when col1 then 'Col1' when col2 then 'Col2' when col3 then 'Col3' when col4 then 'Col4' end ColumnName FROM @T AS t CROSS APPLY ( VALUES (col1), (col2), (col3), (col4)) AS f (x) GROUP BY t.pk, t.col1, t.col2, t.col3, t.col4 Built on top of the code copied from the following link: https://www.sqlservercentral.com/Forums/Dialogs/PostDetails.aspx?PostID=1348803
