  • form validation without reset

    - by Paulo Bueno
    Hi guys Is there a way to check the data sent by a form to a PHP page return to the form page WITHOUT resetting the data sent and show a error? The form has 20 fields and I need to check one of them on a bd. If it fails the user may be redirected to the form page with the form populated and displaying a error message on the field which is 'wrong'. I would like any advice of a technique instead of populating each field using PHP.

  • Automatically generating Guids in Sybase

    - by Daniel Dyson
    I have a table with 42 million records. 32 million have a null value and I would like to generate a new guid for each one. Should I do this in batches?

  • How do I make defensive copy of an object?

    - by kunjaan
    How do I make defensive copies of a Mutable Object which contains a mutable field in an Immutable Object? class ImmutableObject { private final MutableObject immutable_field; ImmutableObject(MutableObject y) { this.immutable_field = y; } MutableObject return_immutable_field() { return immutable_field; } } class MutableObject { public int mutable_field; } The MutableObject does not have a constructor that lets me set the field. The MutableObject's current state should be captured in the Immutable Object and never changed.
