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!

Trying to return identity via Stored Procedure

Asked by lawrmc in Programming for ASP.NET

Tags: procedure, return, identity, stored

Hi
I have an SP that inserts into a table and then returns the @@Identity value. When I fire this in Query Analyser I get the Value back OK.
However, calling from ASP.NET page returns NULL

Heres the bit of code and the SP, any help appreciated


        xCommandUID = New SqlCommand("sp_CreateUID", dbConn)
        xCommandUID.CommandType = Data.CommandType.StoredProcedure
        xParamUID = xCommandUID.Parameters.Add("@PartNumber", Data.SqlDbType.VarChar)
        xParamUID.Value = Session("PARTNUMBER").ToString
        xParamUID = xCommandUID.Parameters.Add("@UID", Data.SqlDbType.Int)
        xParamUID.Direction = Data.ParameterDirection.Output
        Try
            xCommandUID.ExecuteNonQuery()
            lblUID.Visible = True
            lblUID.Text = xCommandUID.Parameters("@UID").SqlValue.ToString


CREATE PROCEDURE sp_CreateUID
(
@PartNumber nvarchar(50),
@UID integer  output
)

AS
declare @CreateDate as  datetime
set @CreateDate = getdate()

INSERT INTO tblTLPCTRL (PART_NUMBER,DATE_CREATED) VALUES
(@PartNumber,@CreateDate) SELECT @@IDENTITY

RETURN @@IDENTITY
GO
