The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

creating a .net CLR SQL Server 2005 Function to return result sets

Asked by xersoft in SQL Server 2005, Microsoft Visual Basic.Net, .Net Editors & IDEs

Tags: clr, sqldatareader, sql

I have the following function. I realize this isn't a good use of CLR functions but I'm just trying to learn right now. What would the return type for this function be or am I returning the result set incorrectly?

I want to use a function so I can later join to this in another query.

   <Microsoft.SqlServer.Server.SqlFunction()> _
    Public Shared Function SelectData(ByVal UserId As Integer) As SqlString


        Using cmd As New SqlCommand
            cmd.CommandText = "select * from SomeTable where userId = " & UserId
            Using dr As SqlDataReader = cmd.ExecuteReader

                SqlContext.Pipe.Send(dr)

            End Using
        End Using

        Return New SqlString("")
    End Function

When I try and register this function I am told via an error that the return type is not correct.

How do I return a result set from a CLR function? Does anyone have any simple examples that pull data from the same database (not some other second data source like an RSS feed)

Thanks so much for the help.
