Edit form + update

[Derokorian]

So I have a form that has data filled in from the database, which i can then change in my form. When I submit it gets processed and an update query is built. My question is this: Is is better to just update all fields possible from the form, or check what has changed and only update those specific fields?

i just update them all myself when i do this. same code can then be used for add or edit.
