Entity Data Model - Original Value

[EricaStar]

How do you configure an entity field in the Entity Data Model to automatically get the original value of the field if the value passed to the field in my code is null? Maybe in the table mapping? I'm not using stored procedures (LINQ). Thanks in advance for your help.

If you're still in db context and want to update your entity only values that were changed will be updated.

Well need to change or update your entity entirely.
