Inserting data into T-SQL; overwrites occur

[jtok]

I am using Visual Studio 2010 for development.
This is a web application using asp.net and vb.net with MS SQL Server 2005 for the database.

I'm having some issues with inserted data being overwritten by the next transaction (if done within a relatively short amount of time, say, roughly several seconds).

I believe this may be related to how I'm exectuing the SQL in code. I have posted below an example of how I'm connecting. My concern is that this is not the correct way to do this. I am using a stored procedure to insert the data, but it does not seem to be the problem, because I have no issues when executing the commands simultaneously using SQL Managment Studio.

Is this an issue with all of the commands using the web.config file's connection string?
Is it an issue with the code I'm using to connect?

Thank You,
JTok

Sub InsertCheckOut()

        Dim InsertQuery As String = "INSERT USING STORED PROCEDURE"

        'Conn.ConnectionString points to the webconfig file's connection string
        Using myConnection As New System.Data.SqlClient.SqlConnection(Conn.ConnectionString)

            Using myCommand As New System.Data.SqlClient.SqlCommand(InsertQuery, myConnection)

                Dim retvalue As Integer

                myConnection.Open()

                retvalue = myCommand.ExecuteNonQuery()

                Console.WriteLine(retvalue)

            End Using

        End Using

    End Sub

What we would need to see (since what you're using is a stored procedure for your inserts) is the Stored Proc you're using.

The above code shows a call to the Stored Proc but nothing of the proc itself which makes it impossible for anyone to determine if there are errors in the proc that might result in row overwrites.

I have included the stored procedure, and the way I retrieve some guids for use with it.

Out of curiosity... Why do you feel the stored procedure may still be the cause of my problems, if the overwriting only seems to happen when done through my web application and not when executed directly from two sql server management windows?

Thank You for Your Help,
JTok

Here is an example of how the GUIDs/IDs are collected for use with the stored procedure:

Using Conn As New SqlConnection With {.ConnectionString = ConfigurationManager.ConnectionStrings("ConnName").ConnectionString}
            Using cmdSelect As New SqlCommand(QueryString, Conn)
                Conn.Open()

                Using dtrReader As SqlDataReader = cmdSelect.ExecuteReader
                    If dtrReader.HasRows Then
                        While dtrReader.Read
                            If dtrReader.IsDBNull(0) Then
                                Return QueryExecute
                            Else
                                QueryExecute = (dtrReader(SearchString)).ToString
                                Return QueryExecute
                            End If
                        End While
                    End If

                End Using
            End Using
        End Using

And here is the stored procedure:

The reason I believe the issue is the stored proc and not the code you originally provided is because all the code you provided shows is opening the connection, utilizing the stored proc to insert data and closing the connection.

If all it's doing is calling to the stored proc and nothing more then, logically, the stored proc is the source of the overwrite.

Maybe someone looking over the HUGE stored proc you provided above will be able to find the issue, or, maybe I was wrong... either way, it doesn't hurt to have as much info as possible to work with when attempting to find the source of an issue :)

[jtok]

It is kinda big, huh?

Found another interesting quirk related to this issue...
When two users run the page that opens the connection and executes the stored procedure, another page is immediately called that retrieves that data and presents it in a more legible format. That page is ALWAYS correct. Yet, when you go searching for the data that was just inserted, it may have been overwritten.

[Lusiphur]

>>When two users run the page that opens the connection and executes the stored procedure...That page is ALWAYS correct.

Generally this can be attributed to the fact that you are utilizing 'local' variable sets on this page as opposed to the information present in the database. Each user gets their own 'session' on the server which contains all the local variables from their input and, unless you're drawing your results from the DB on the generation of the 'result' page you're presenting, all they're getting back is the information they submitted regurgitated in the 'formatted' view.

[jtok]

It is querying the database directly.
The first page, after inserting the data through the stored proc, retrieves the necessary id column and then passes that as a query string to the result page, which then runs a query and retrieves the data.

Sounds impossible, I know, but I can't find a solution.

[Lusiphur]

Ok... well....

Here's my theory (and no, I didn't make it all the way through your Stored Proc, sorry)...

1. User 1 enters their input and submits
2. User 1 receives confirmation of their input from the DB
3. User 2 enters their input and submits
4. User 2 receives confirmation of their input from the DB
5. Both users receive correct information as, while they seem simultaneous in their entry they're actually still 'in order' based on the fractions of fractions of seconds it takes for the process to complete
6. Entry 2 is assigned some sort of transaction key that is identical to Entry 1's transaction key due to a mis-code in the stored proc (stored proc may be giving both a transaction # of, say, 12) generally caused by the proc checking for existing key prior to processing and applying transaction key after processing, this can be avoided by having transaction keys auto-generated by the server instead of code
7. Entry 1 is overwritten due to Entry 2 having identical transaction key

This is just my 'theory' on what's going on however. As I said, I've been kind of busy lately and haven't gotten through all of your code to confirm it.

[jtok]

No problem. I appreciate all the help you have given, and that gives me a good place to start looking.
