错误：关键字“FOR”附近的语法不正确

Question

我很难调试这个SQL查询，我得到了这个错误：

Msg 102, Level 15, State 1, Line 13
Incorrect syntax near '('.
Msg 156, Level 15, State 1, Line 13
Incorrect syntax near the keyword 'FOR'.

这是我的疑问：

SELECT SID,CSID,M,QCL,STUFF((SELECT distinct ',' + QUOTENAME(TN) from tmpTbl FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'),1,1,'')
            from 
            (
              select t.SID, t.CSID, t.M, w.QCL,t.TC,t.TN 
              from tmpTbl AS t
              inner join WoOr AS w
              on t.WO = WoOr.WO
              where t.IsSelected = 0
            ) x
            pivot 
            (
                count(TC)
                for TN in (STUFF((SELECT distinct ',' + QUOTENAME(TN) from tmpTbl FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'),1,1,''))
            ) p 

感谢您提前！

for TN in (STUFF((SELECT distinct ',' + QUOTENAME(TN) from tmpTbl FOR XML   
PATH(''),TYPE).value('.','NVARCHAR(MAX)'),1,1,''))

使用pivot功能，您无法执行动态列。除非你使用动态sql，否则它们需要硬编码。
