Basically i have a query string that when i hardcode in the catalogue value its fine. when I try adding it via a variable it just doesn't pick it up.

This works:

  Dim WaspConnection As New SqlConnection("Data Source=JURA;Initial Catalog=WaspTrackAsset_NROI;User id=" & ConfigurationManager.AppSettings("WASPDBUserName") & ";Password='" & ConfigurationManager.AppSettings("WASPDBPassword").ToString & "';")

This doesn't:

Public Sub GetWASPAcr()

    connection.Open()

    Dim dt As New DataTable()
    Dim username As String = HttpContext.Current.User.Identity.Name
    Dim sqlCmd As New SqlCommand("SELECT WASPDatabase FROM dbo.aspnet_Users WHERE UserName = '" & username & "'", connection)

    Dim sqlDa As New SqlDataAdapter(sqlCmd)

    sqlDa.Fill(dt)

    If dt.Rows.Count > 0 Then

        For i As Integer = 0 To dt.Rows.Count - 1
            If dt.Rows(i)("WASPDatabase") Is DBNull.Value Then
                WASP = ""
            Else
                WASP = "WaspTrackAsset_" + dt.Rows(i)("WASPDatabase")
            End If

        Next

    End If
    connection.Close()

End Sub

Dim WaspConnection As New SqlConnection("Data Source=JURA;Initial Catalog=" & WASP & ";User id=" & ConfigurationManager.AppSettings("WASPDBUserName") & ";Password='" & ConfigurationManager.AppSettings("WASPDBPassword").ToString & "';")

When I debug the catalog is empty in the query string but the WASP variable holds the value "WaspTrackAsset_NROI"

Any idea's why?
