sql - 在 T-SQL 中将列值转置为行

Question

我知道这可能以前被问过，但我真的找不到答案。我有一个名为的临时表#TEMP，如下所示：

+===============================+=============================+
| NAME                          | ATTRIBUTE                   |
+===============================+=============================+                                  
| BadgeType                     | Permanent                   |
+-------------------------------+-----------------------------+
| PrimaryLocationInCompany      | No                          |
+-------------------------------+-----------------------------+
| AdminAccessToProductionServer | No                          |
+-------------------------------+-----------------------------+
| AccessToImportantFIles        | No                          |
+-------------------------------+-----------------------------+
| Waiver_Number                 | 56987                       |
+-------------------------------+-----------------------------+
| Summary                       | User not much active        |
+-------------------------------+-----------------------------+
| TimeStamp                     | 3/3/2009                    |
+-------------------------------+-----------------------------+
| UserID                        | 86478925                    |
+-------------------------------+-----------------------------+

我想要做的是将Name和Attribute值都转置为行。这些Attribute值可能会有所不同，但这些Name值始终是固定的。

结果应如下所示：

+----------+---------------+------------------------------+--------------------------------+-----------------------+--------------------------------------------------------+----------+-----------+
| UserID   | BadgeType     | PrimaryLocationIntelFacility | adminAccessToProductionServer  | AccessToClassifiedData| Info_Sec_Waiver_Number                                 | Summary  | TimeStamp |
+----------+---------------+------------------------------+--------------------------------+-----------------------+--------------------------------------------------------+----------+-----------+
| 11313403 | GREEN         | No                           | No                             | No                    | This contingent worker is eligible for remote access.  | 3/3/2009 |           |
+----------+---------------+------------------------------+--------------------------------+-----------------------+--------------------------------------------------------+----------+-----------+

Answer 1

尝试这个

SELECT UserID,BadgeType,PrimaryLocationInCompany,AdminAccessToProductionServer,AccessToImportantFIles,WaiverNumber,Summary,[TimeStamp]
FROM
(
    SELECT * FROM #Temp
) p
PIVOT
(
    MIN([ATTRIBUTE]) FOR [NAME] IN(BadgeType,PrimaryLocationInCompany,AdminAccessToProductionServer,AccessToImportantFIles,WaiverNumber,Summary,[TimeStamp],UserID)
) T

还要检查下面的动态列

DECLARE @cols AS NVARCHAR(MAX),
    @query  AS NVARCHAR(MAX)

select @cols = STUFF((SELECT ',' + [NAME]
                    from #Temp
                    group by [NAME]
            FOR XML PATH('')) 
        ,1,1,'')

set @query = 'SELECT  ' + @cols + ' from 
             (
                select * from #Temp
            ) x
            pivot 
            (
                MAX([ATTRIBUTE])
                for [NAME] in (' + @cols + ')
            ) p '

execute(@query)
