SQL函数在查询和异常处理中的应用

在查询中，我使用了一个SQL函数（调用.NET函数进行xml转换）

当函数ApplyXMLTransform遇到异常时，整个查询将启动。。。有没有办法防止异常破坏整个记录集（在查询方面，我意识到我可以修改函数来处理托管代码中的异常）

异常本身也是一个神秘的故事，因为当我查询罪魁祸首记录时，我没有看到构成异常的无效字符等。。。但那是另一罐虫子。。。以下是错误：

Msg 6522, Level 16, State 1, Line 3
A .NET Framework error occurred during execution of user-defined routine or aggregate "ApplyXsltTransform": 
System.Xml.XmlException: Invalid character in the given encoding. Line 21, position 417.
System.Xml.XmlException: 
   at System.Xml.XmlTextReaderImpl.Throw(Exception e)
   at System.Xml.XmlTextReaderImpl.InvalidCharRecovery(Int32& bytesCount, Int32& charsCount)
   at System.Xml.XmlTextReaderImpl.GetChars(Int32 maxCharsCount)
   at System.Xml.XmlTextReaderImpl.ReadData()
   at System.Xml.XmlTextReaderImpl.ParseText(Int32& startPos, Int32& endPos, Int32& outOrChars)
   at System.Xml.XmlTextReaderImpl.ParseText()
   at System.Xml.XmlTextReaderImpl.ParseElementContent()
   at System.Xml.XmlWriter.WriteNode(XmlReader reader, Boolean defattr)
   at System.Data.SqlTypes.SqlXml.CreateMemoryStreamFromXmlReader(XmlReader reader)
   at System.Data.SqlTypes.SqlXml..ctor(XmlReader value)
   at NF.Sql.Extensions.XSLTTransform.Transform(SqlXml inputDataXML, SqlXml inputTransformXML)
.

捕获函数中的异常，并返回一个漂亮的小字符串“Error accurrent”或其他内容。谢谢，这正是我正在做的，并返回异常详细信息。我想真的没有办法通过查询来处理它。。。
