PIVOT with varchar datatype
提问by NicoRiff
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 carchar columns. I have this table:
我正在尝试对表中的一些数据进行 PIVOT,但我不能这样做,因为我找不到使用 carchar 列的方法。我有这张桌子:
And what I need is this:
我需要的是这个:
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.
我需要使用 'ug_label' 行数据作为列。由于数据类型是 VARCHAR,我不能在 PIVOT 中使用聚合函数。
I think I might need something like this:
我想我可能需要这样的东西:
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??.
有人能帮我吗??。
Thanks.
谢谢。

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
:
您仍然可以使用 PIVOT 函数来获取结果,但由于您正在聚合 a,因此varchar
您必须使用max
或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
