使用pivotsql的动态列名

大家好，我对SQL还比较陌生，在线搜索还没有为我提供解决方案，或者它就在我面前，但超出了我的知识范围：/。希望能在这里碰碰运气，谢谢

Table:   Servers
Columns: ServerUrl               ServerName
Rows:    //server0001/space0/    Telescope1
         //server0001/space1/    Space
         //server0001/space2/    Planet

Table:   Projects
Columns: ServerUrl               Name          Entity     Type
Rows:    //server0001/space0/    Field1        E          T1
         //server0001/space1/    Field2        T          T1
         //server0001/space2/    Field3        E          T3

通过下面的存储过程，我能够以如下方式返回数据：

因此，ServerUrl被用作列名，如下所示，但我希望它改为ServerName。我知道可以将列设置为ServerName，但由于ServerUrl可能会更改，我将如何动态地进行设置

--- Returned Data Begin ---
Stored Procedure Results:
Columns: Name    Entity  //server0001/space0/   ...space1  ...space2
Rows:    Field1  E       T1                     NULL       NULL
         Field2  T       NULL                   T2         NULL
         Field3  E       NULL                   NULL       T3     

--- Returned Data End ---

***下面的存储过程用于获取上面的结果

--- STORED PROCEDURE BEGIN ---
DECLARE @Projects varchar(max)
SELECT @ProgramList = COALESCE(@Projects + '], [', '') + ServerURL FROM
Servers ORDER BY ServerURL

SET @ProgramList = CONCAT ('[', @ProgramList + ']')

DECLARE @sql nvarchar(max)
SET @sql = 'select * from ( select P.Name, P.Entity, P.Field, P.ServerUrl 
FROM ProjectFields as P ) as P pivot (min(P.Field) for P.ServerUrl in (' + 
@Projects + ')) as PIV ORDER BY Name'

EXEC sp_executesql @sql1
--- STORED PROCEDURE END ---

谢谢：

您的存储过程看起来不完整或更改了某些内容，但我相信您正在寻找以下内容：

DECLARE @ProgramList VARCHAR(MAX);
SELECT @ProgramList = STUFF((SELECT ',' + QUOTENAME(ServerName) FROM [Servers] ORDER BY ServerURL FOR XML PATH ('')), 1, 1, '');

DECLARE @sql VARCHAR(MAX);
SELECT @sql = '
SELECT *
FROM
(
    SELECT P.Name,
           P.Entity,
           P.Field,
           S.ServerName
    FROM ProjectFields AS P
    JOIN [Servers] AS S
        ON S.ServerURL = P.ServerURL
) AS P
PIVOT
(
    MIN(Field) FOR ServerName IN (' + @ProgramList + ')
) AS PIV
ORDER BY PIV.Name;';

--PRINT @sql;
EXEC sp_executesql @sql;

将@ProgramList select更改为ServerName而不是ServerURL，并将动态语句更改为类似“select*FROM select P.Name、P.Entity、P.Field、S.ServerName FROM ProjectFields AS P JOIN Servers AS S ON S.ServerURL=P.ServerURL AS P PIVOT MINField FOR ServerName IN'+@ProgramList+'AS PIV ORDER BY PIV.Name；”非常感谢ZLK，它很有魅力，是的，你是对的，我改变了一些事情，对不起。
