Question

我正在使用SQL Server 2008创建动态数据透视查询，但卡在STUFF。

示例：

Declare @col as nvarchar(max) 
Declare @tablename as nvarchar(max) 

SET @col = 'STUFF((SELECT '','' + QUOTENAME(cola) 
                from ' + @tablename + '
                group by cola
                  order by cola
        FOR XML PATH(''''), TYPE
        ).value(''.'', ''NVARCHAR(MAX)'') 
    ,1,1,'''')'

 execute(@col)

 print @col;

错误

 Incorrect syntax near the keyword 'order'.

Declare @col as nvarchar(max) 
Declare @tablename as nvarchar(max) = N'Table1'

set @col = N'SELECT
                  STUFF((
                        SELECT
                              '','' + QUOTENAME(cola)
                        FROM ' + @tablename + N'
                        GROUP BY
                              cola
                        ORDER BY
                              cola
                        FOR xml PATH (''''), TYPE
                  )
                  .value(''.'', ''NVARCHAR(MAX)''), 1, 1, '''');'

execute(@col)
;

不是exec @col

Meem，我修改了你的查询，看起来应该是这样的。

Declare @col as nvarchar(max) 
Declare @tablename as nvarchar(max) 

set @col = 'REF_REFM_CODE'
set @tablename = 'tblKeywords'
SET @col = 'Select STUFF((SELECT ' + ''','' + ' + @col + '
                from ' + @tablename + '
                group by ' + @col +
                ' order by ' + @col + 
        ' FOR XML PATH(''''), TYPE
        ).value(''.'', ''NVARCHAR(MAX)'') 
    ,1,1,'''')'

 execute(@col)
 print @col;

请参阅此Demo in SQL Fiddle.

将@col声明为nvarchar（max）将@tablename声明为nvarchar（max）

SET @col =＆＃39; STUFF（（SELECT＆＃39;＆＃39;，＆＃39;＆＃39; + QUOTENAME（可乐）来自＆＃39;＆＃39; + @tablename +＆＃39;＆＃39;＆＃39; 可乐集团由可乐订购 FOR XML PATH（＆＃39;＆＃39;＆＃39;＆＃39;），TYPE ）.value（＆＃39;＆＃39;。＆＃39;＆＃39;，＆＃39;＆＃39; NVARCHAR（MAX）＆＃39;＆＃39;），1,1，＆＃39;＆＃39;＆＃39;＆＃39;）＆＃39; 执行（@col）

print @col;
