sql-server - 如何捕获从链接服务器返回的错误消息？

Question

如何捕获从链接服务器返回的错误消息？

例如，如果我在SQL Server Management Studio中运行以下命令:

BEGIN TRY
 exec ('select * from xxx') at my_linked_server
END TRY

BEGIN CATCH
  print  'ErrorNumber...'+  CAST(ERROR_NUMBER() as varchar)
  print  'ErrorSeverity...'+  CAST(ERROR_SEVERITY() as varchar)
  print  'ErrorState...'+  CAST(ERROR_STATE() as varchar)
  print  'ErrorProcedure...'+ IsNull(ERROR_PROCEDURE(),'')
  print  'ErrorLine...'+  CAST(ERROR_LINE() as varchar)
  print  'ErrorMessage...'+  IsNull(ERROR_MESSAGE(),'')
END CATCH

我得到以下结果:

OLE DB provider "MSDASQL" for linked server "my_linked_server" returned message "[Informix][Informix ODBC Driver][Informix]The specified table (xxx) is not in the database.". ErrorNumber...7215 ErrorSeverity...17 ErrorState...1 ErrorProcedure... ErrorLine...3 ErrorMessage...Could not execute statement on remote server 'my_linked_server'.

SQL Server是否存储OLE DB提供程序错误？ (捕获此信息以进行调试将很有用。)

我有同样的问题。我通过将try catch传递到链接服务器并使用OUTPUT参数找回了错误来找到解决方法。例如:

    SET @command = '
    BEGIN TRY
        exec (''select * from xxx'') 
        SELECT @resultOUT = @@ERROR
    END TRY
    BEGIN CATCH
        SELECT @resultOUT = @@ERROR
    END CATCH'
    SET @ParmDefinition = N'@resultOUT nvarchar(5) OUTPUT'
    exec my_linked_server.sp_executesql 
        @command, 
        @ParmDefinition, 
        @resultOUT=@result OUTPUT
