＆LT;转换为＆lt;在sql server中

Question

我的表格中有一些数据

当我使用此查询选择数据时

select TblActionHistories.Comments from TblActionHistories WHERE TblActionHistories.Entity=CAST('Task' AS VARCHAR) AND EntityId=CAST(32 AS VARCHAR)

这样就好了

Task- <b>T1</b> has been added by Swapnil Sharma
Task- <b>T1</b> status changed to <b>In Progress</b> by Swapnil Sharma<br/>

但现在我希望我的上述结果＃使用stuff分隔，所以我正在使用此

SELECT STUFF((SELECT '#' + ISNULL(CAST(TblActionHistories.Comments AS VARCHAR(MAX)),'') FROM TblActionHistories WHERE TblActionHistories.Entity=CAST('Task' AS VARCHAR) AND EntityId=CAST(32 AS VARCHAR) for xml path ('')),1,1,'')

它给了我这个

Task- <b>T1</b> has been added by Swapnil Sharma#Task- <b>T1</b> status changed to <b>In Progress</b> by Swapnil Sharma<br/>

你可以清楚地看到所有的特殊字符。喜欢＆lt; ＆GT;分别转换为< >

请帮助我，我希望他们以原始格式出现

我找到了IvanG建议的解决方案

SELECT STUFF((SELECT '#' + ISNULL(CAST(TblActionHistories.Comments AS VARCHAR(MAX)),'') FROM TblActionHistories WHERE TblActionHistories.Entity=CAST('Task' AS VARCHAR) AND EntityId=CAST(32 AS VARCHAR) for xml path(''), root('MyString'), type ).value('/MyString[1]','varchar(max)') ,1,1,'')

尝试转换为NVARCHAR而不是VARCHAR

SELECT STUFF((SELECT '#' + ISNULL(CAST(TblActionHistories.Comments AS NVARCHAR(MAX)),'') FROM TblActionHistories WHERE TblActionHistories.Entity=CAST('Task' AS NVARCHAR) AND EntityId=CAST(32 AS VARCHAR) for xml path ('')),1,1,'')
