我想转置下面的表格,以便第一列(tabLabel)成为页眉。我需要动态执行此操作,因为行数未知。我已经看到了关于动态枢纽的帖子,但我不完全明白这将如何完成。动态数据透视SQL列数据到页眉

tabLabel   documentId recipientId  Date value 
Street Address   1   1   NULL 123 mockingbird lane 
City     1   1   NULL city 
Patient Phone   1   1   NULL 999-999-9999 
Responsible Phone  1   1   NULL 999-999-9999 
Gross Income   1   1   NULL 999 
Monthly Mortgage/Rent 1   1   NULL 100 
Monthly Auto   1   1   NULL 200 

最终版本:

Street Address   City Patient Phone Responsible Phone Gross Income Monthly Mortage/Rent Monthly Auto documentId recipientId Date 
123 mockingbird lane city 999-999-9999 999-999-9999  999   100     200   1    1   NULL 

选择查询的原始表:

SELECT [tabLabel] 
    ,[documentId] 
    ,[recipientId] 
    ,[Date] 
    ,[value] 
    FROM [zDocusign_Document_Tab_Fields] 
+0

你能做到这一点在你的代码?这会更容易阅读。 – user2023861

@ user2023861你的意思是插入我的创建表或插入语句? –

我的意思是,如果您正在将这些数据读入某个应用程序,则可以将数据转到那里。我知道在C#中这样做会比我在Google上搜索“sql server dynamic pivot”时看到的要容易得多。 – user2023861

动态SQL

-- Build colums 
DECLARE @cols NVARCHAR(MAX) 
SELECT @cols = STUFF((
    SELECT DISTINCT ',' + QUOTENAME([tabLabel]) 
    FROM zDocusign_Document_Tab_Fields 
    FOR XML PATH('') 
), 1, 1, '') 
-- Selecting as FOR XML PATH will give you a string value with all of the fields combined 
-- separated by comma. Stuff simply removes the first comma. 
-- Quotename wraps the [tabLabel] value in brackets to allow for spaces in column name 
-- You end up with 
-- [City],[Gross Income],[Monthly Auto],[Monthly Mortgage/Rent],[Patient Phone],[Responsible Phone],[Street Address] 

-- Build sql 
DECLARE @sql NVARCHAR(MAX) 
SET  @sql = N' 
    SELECT ' + @cols +' 
    FROM zDocusign_Document_Tab_Fields 
    PIVOT (
     MAX([value]) 
     FOR [tabLabel] IN (' + @cols + ') 
    ) p 
' 

-- Execute Sql 
EXEC(@sql)

非常感谢!立即工作! –
