PIVOT with varchar datatype

NicoRiff picture NicoRiff · Feb 7, 2014 · Viewed 28.2k times · Source

I´m trying to PIVOT some data in a table, but I cannot do it because I do not find the way to do it using varchar columns. I have this table:

And what I need is this:

I need to use the 'ug_label' row data as columns. As the datatype is VARCHAR, I cannot use an agregate function inside the PIVOT.

I think I might need something like this:

SELECT *
FROM
(SELECT [c_id]
      ,[c_lname] as [Apellido]
      ,[c_fname] as [Nombre]
      ,[c_nick_name] as [documento]      
      ,[ut_text] 
      ,f.ug_label
  FROM [pegasys].[dbo].[cardholder] c
  inner join [pegasys].[dbo].[udftext] u on c.c_id = u.ut_cardholder_id 
  inner join [pegasys].[dbo].[udfgen] f on u.ut_udfgen_id = f.ug_id) AS S  
PIVOT
(
    UT_TEXT
    FOR
    [UG_LABEL]
    IN ([Torre], [Cuit], [Empresa], [Departamento])
) as s

Can someone help me??.

Thanks.

You can still use the PIVOT function to get the result but since you are aggregating a varchar you have to use either max or min:

SELECT *
FROM
(
  SELECT [c_id]
      ,[c_lname] as [Apellido]
      ,[c_fname] as [Nombre]
      ,[c_nick_name] as [documento]      
      ,[ut_text] 
      ,f.ug_label
  FROM [pegasys].[dbo].[cardholder] c
  inner join [pegasys].[dbo].[udftext] u on c.c_id = u.ut_cardholder_id 
  inner join [pegasys].[dbo].[udfgen] f on u.ut_udfgen_id = f.ug_id
) d  
PIVOT
(
    max(ut_text)
    FOR UG_LABEL IN ([Torre], [Cuit], [Empresa], [Departamento])
) p
