Cannot Delete

[johnsev]

I am able to read, create, and update records but I cannot delete. I am using DeleteById(160) where the Id is currently hard coded. Here is the message I receive.

Format of the initialization string does not conform to specification starting at index 0.

I have noticed that others have similar problem but nothing I have tried is working. Again, the connection string works for everything but Delete. My connection string is...
Server=athena;Database=Appil;User Id=ABC;password=def;multipleactiveresultsets=True;

I am accessing the database over VPN - could that be a problem?

Strange it ought to work, what happens if you try

var id = 160;
.DeleteById(id)

or

.Delete(Id: 160)

I get the same error message in all cases. I even tried creating a stored procedure where I simply pass the ID and the sp deletes the record. I get the same error message. Here is the full error message.

Could it be a permissions error or maybe the delete is generating an error?

[johnsev]

I logged in with SSMS using those same credentials to confirm I can delete the record in question. I also verified the stored proc worked before trying to use it with Simple.Data.

Can you delete the record using vanilla ado.net c# and the same connection string?

[johnsev]

I'll give that a try however, I am working in VB.nethttp://vb.net.

It works in ADO.net. Here is my code. It is an action in a WebAPI written in VB.net.

`
Public Async Function DeleteValue(ByVal dbName As String, ByVal id As Integer) As Task(Of IHttpActionResult)
Await Task.Yield
Dim db As Object
Try

            //This does not work
            db = Database.OpenConnection(dbName)
            db.IO.DeleteByID(id)

            //This works
            Using conn As SqlConnection = New SqlConnection(ConfigurationManager.ConnectionStrings(dbName).ConnectionString)
                Using cmd As SqlCommand = New SqlCommand("DELETE IO WHERE ID = " & id)
                    cmd.Connection = conn
                    conn.Open()
                    cmd.ExecuteNonQuery()
                    conn.Close()
                End Using
            End Using

            Return StatusCode(HttpStatusCode.Accepted)
        Catch ex As Exception
            If IsNothing(db) Then
                Throw
                //todo: error hanlder for bad db connection
            Else
                Throw
                //todo: Error Handlers for a delete failure
            End If
        End Try
    End Function

Not sure why the first few lines of code are not formatted as code in my previous post. I thought it was perhaps the apostrophe used as a comment in VB.net so I changed it to // even though it is not syntactially correct in VB.

There dbName is the name of your connection. Database.OpenConnection expects a connectionString not so much the named configuration value. To open by a connectionName you should be using Database.OpenNamedConnection instead which does what you are looking for.

Using Database.OpenConnection throws the Format of the initialization string does not conform to specification starting at index 0. exception because the dbName value is not a well-formed connectionString.

[johnsev]

Ugh! I'm a bonehead. I've been looking at this code too long and just looked over that. Everywhere else in my code I use OpenNamedConnection except for here. Also, because it only errored when I tried the delete statement and not on OpenConnection(dbName) I just assumed that the connection was good. I guess it doesn't try making the connection until some work needs to be done.

Sorry for spinning you up over nothing and thanks for your help.
