    I'm evaluating OpenAccess ORM and I noticed that if I delete a column from a table in the database and the I update the DB schema (I'm doing a reverse synchronization where I'm changing the object model from the DB table structure), it's the change is detected correctly but the column that now is missing from the db is not deleted.

    Is that a known bug?

    Hi Andrea Nagar,

     Are you using the 'Reversemapping wizard' or the OpenAccess Domain Model (DSL designer) to generate your classes?
    If you are using the 'Reversemapping wizard', the deleted column is detected and the corresponding field is removed from the class. The wizard generates 2 files for each class - <classname>.cs which is generated only and has the property implementations and  - <classname.Telerik.OpenAccess.cs> which has the field declarations.
    You would need to manually delete/ comment the property implementation for the deleted field. We do not regenerate this file since it may contain user changes.

    Do let me know if you need further assistance.

    All the best,
    the Telerik team
