我有一张这样的桌子......

CustomerID   DBColumnName   Data
--------------------------------------
1            FirstName      Joe
1            MiddleName     S
1            LastName       Smith
1            Date           12/12/2009
2            FirstName      Sam
2            MiddleName     S
2            LastName       Freddrick
2            Date           1/12/2009
3            FirstName      Jaime
3            MiddleName     S
3            LastName       Carol
3            Date           12/1/2009

我想要这个......

这可能使用PIVOT吗？

CustomerID  FirstName   MiddleName          LastName        Date
----------------------------------------------------------------------
1           Joe             S               Smith           12/12/2009
2           Sam             S               Freddrick       1/12/2009
3           Jaime           S               Carol           12/1/2009

我有一个有趣的难题,我认为可以用纯粹的SQL解决.我有类似于以下的表:

responses:

user_id | question_id | body
----------------------------
1       | 1           | Yes
2       | 1           | Yes
1       | 2           | Yes
2       | 2           | No
1       | 3           | No
2       | 3           | No


questions:

id | body
-------------------------
1 | Do you like apples?
2 | Do you like oranges?
3 | Do you like carrots?

我想得到以下输出

user_id | Do you like apples? | Do you like oranges? | Do you like carrots?
---------------------------------------------------------------------------
1 …

我知道你有多个主题涉及到这一点.但是,我找不到满足我需求的.我需要(按需)将深度表数据透视到宽输出表.这里的问题是我不能使用Pivot的聚合,因为它会占用输出中需要的响应.我已经找到了解决方案,但我认为这不是最好的,因为它需要无数的左连接才能工作.我已将所有尝试和说明包括在内如下:

-- Sql Server 2008 db.
-- Deep table structure (not subject to modification) contains name/value pairs with a userId as
-- foreign key.  In many cases there can be MORE THAN ONE itemValue given by the user for the
-- itemName such as if asked their race, can answer White + Hispanic, etc.  Each response is stored
-- as a seperate record - this cannot currently be changed.

-- Goal: pivot deep data to wide while also compressing result …

我有一个项目列表 - 每个项目都有一个标题,加上一堆属性,包括一个日期.

如果我将日期放入数据透视表的行框中,然后将其分组,并将标题放在下面 - 所以我有年,季度,创建,标题,我得到了一个很好的列表,列出了我的数据中的所有标题,分组按年,季度和月份.

但是我还想显示每个标题旁边的所有其他属性 - 每行的所有相关数据.对于纹理的,我不想计算它们 - 我只想列出整个数据集,但按日期分组.如果我将它们添加到其他数据透视表框中,它会开始执行通常的计数...

拥有数据透视表的所有额外过滤能力会很好,但我是否太难了？

谢谢你的帮助.

想象一下,我有这张桌子:

Column A | Column B | Column C
------------------------------
   111         X        10
   111         Y        12

如何查询此表以显示如下结果:

Column A |     X     |      Y
-----------------------------------
   111         10           12

这是我的查询

CREATE view pivmehis WITH ENCRYPTION
as 
SELECT APPROVED, [Not Approved] as REJECT, NULL
FROM 
(SELECT MgtApproval
from LeaveRequest) l
PIVOT 
(
Sum (SchedId) --I DON'T WANT TO SUM THIS COLUMN
FOR MgtApproval IN 
([APPROVED], [REJECT], [NULL])) as pvt

原始表结果:

MgtApproval      SchedId
Approved           1
Reject             2
Null               3
Approved           4
Reject             5
Null               6

这是我想要查看的结果:

Approved    Reject        Null
1           2           3         
4           5           6         

请帮我解决一下这个.我完全陷入困境.我有编码器块或什么的.

我有下表

ID     Name        Cost     Included
----   ----------  -------  ----------
1      Package1    10.00    Yes
2      Package2    20.00    No
3      Package3    20.00    Yes

我想交叉显示这些信息,要显示如下例子,表格中会有更多列.

Type        Package1     Package2       Package3
-----       ------------ -----------    ----------
Name        Package1     Package2       Package3
Cost        10.00        20.00          30.00
Included    Yes          No             Yes
