    Como puedo hacer para detectar registros duplicados?

    Asked by RafaChanD on May 13, 2013 at 11:45 AM

    Profavor me podrán orientar informándome si tienen alguna rutina u opción para poder detectar duplicidad en los registros a través de un campo específico.


    Tengo en mi formulario el campor de RFC (Registro Federal de Contribuyentes), es un campo alfanumérico a través del cual se solicta al participante ingrese al registro de esta manera este campo es único y debe de evitar que se vuelva a dar de alta asi es que ya se ingresó el dato.

    Por su atneción gracias.

    You can search based on some of the user's personal information to check for duplicates within the Form Submissions in the Submissions Control Panel where you view all of the submissions you've received.

    Additionally you can place a limitation on your form to prevent more than one submission per person or even a question to make sure the same information is not accepted again.
