Description pesco CLA 2010-11-02 12:42:11 EDT 
Build Identifier: 

As the dual of HANDLE_UNSET_AS_NULL, we should have a CONVERT_UNSET_TO_NULL option with the following behavior:

- when an unset efeature is stored the database column will get a null value
- when a null is read from the database then the efeature is set to null


Reproducible: Always
Comment 1 Martin Taal CLA 2010-11-03 13:19:15 EDT 
One question though:
- when a null is read from the database then the efeature is set to null

should the feature also be set to unset when reading a null from the database?

Comment 2 Martin Taal CLA 2010-11-03 13:20:17 EDT 
Hmm forget my question, this can be achieved by using the HANDLE_UNSET_AS_NULL option together with this new proposed option.
