En el codigo que esta de color verde, como puedo saber si ese valor de
la columna 3, sea no nullo para despues convertilo a un numero si no que no haga nada, ¿Como hago eso?, ya que a veces el resultado puede borrarse y debe quedar vacio, cuando borro en el objeto, lo deja con 0, por defecto.
Necesito vuestra ayuda,
saludos y gracias de antemano. |
