When textbox is null it will not insert data

[ayakamacy]

Hello there, I have 2 tables in my database, all i want to do is when the time txtJobstart is null then it will not insert the data to the tbl2 but all the data from other fields will save to tbl1.

If txtJobStart.Text = "" Then
            'Don't save, do nothing
        Else
            Dim constr As String = ConStrX
            Using test As New SqlConnection(constr)
                Using probe As New SqlCommand("JobStartMonitoring")
                    Using sda As New SqlDataAdapter()
                        probe.CommandType = CommandType.StoredProcedure
                        probe.Parameters.AddWithValue("@JobStart", txtJobStart.Text)
                        probe.Parameters.AddWithValue("@TotalNoOfPins", txtTotalPins.Text)
                        probe.Parameters.AddWithValue("@TotalNoOfJobs", txtTotalJO.Text)
                        probe.Connection = test
                        test.Open()
                        probe.ExecuteNonQuery()
                        test.Close()
                    End Using
                End Using
            End Using
        End If
