yes  but why          Select CustomerID       Min Case DBColumnName When  FirstName  Then Data End  FirstName       Min Case DBColumnName When  MiddleName  Then Data End  MiddleName       Min Case DBColumnName When  LastName  Then Data End  LastName       Min Case DBColumnName When  Date  Then Data End  Date    From table    Group By CustomerId

Try this   SELECT CUSTOMER ID  MAX FIRSTNAME  AS FIRSTNAME  MAX LASTNAME  AS LASTNAME      FROM    SELECT CUSTOMER ID          CASE WHEN DBCOLUMNNAME  FirstName  then DATA ELSE NULL END AS FIRSTNAME         CASE WHEN DBCOLUMNNAME  LastName  then DATA ELSE NULL END AS LASTNAME              and so on     GROUP BY CUSTOMER ID    TEMP  GROUP BY CUSTOMER ID

The OP didn t actually need to pivot without agregation but for those of you coming here to know how see   sql parameterised cte query  The answer to that question involves a situation where pivot without aggregation is needed so an example of doing it is part of the solution

WITH pivot data AS   SELECT customerid  -- Grouping Column dbcolumnname  -- Spreading Column data -- Aggregate Column FROM pivot2    SELECT customerid   firstname    middlename    lastname  FROM pivot data PIVOT  max data  FOR dbcolumnname IN   firstname   middlename   lastname    AS p

You can use the MAX aggregate  it would still work  MAX of one value   that value    In this case  you could also self join 5 times on customerid  filter by dbColumnName per table reference  It may work out better

Here is a great way to build dynamic fields for a pivot query   --summarize values to a tmp table  declare  STR varchar 1000  SELECT   STr    COALESCE  STr               QUOTENAME DateRange   from  select distinct DateRange  ID from   pivot d order by ID   ---see the fields generated  print  STr  exec         pivot code     pivot  avg SalesAmt  for DateRange IN       Str      AS P order by Decile
