Question

我正在尝试使用逗号分隔来获取两列。此代码

SELECT STUFF(( SELECT ',' + Cast(Column1 As varchar(50))+'_'+Cast(Column2 As varchar(50)) FROM Table FOR XML PATH(''), TYPE).value('.', NVARCHAR(MAX)), 1, 1, '') As Result

对我有用。但我需要在动态查询字符串中使用它，当我尝试这样做时会出现错误。

Declare @String AS NVARCHAR(MAX)
Set @string='SELECT STUFF(( SELECT ',' + Cast(Column1 As varchar(50))+'_'+Cast(Column2 As varchar(50)) FROM Table FOR XML PATH(''), TYPE).value('.', NVARCHAR(MAX)), 1, 1, '') As Result'
EXEC sp_executesql @String
