Removing a column by inheriting doctrine mapping

Question

What I want to do is optimize my database by removing unnecessary fields from ProductTable.

My app is based on e-commerce Sonata. I want to remove the "ShortDescription" field from the Product object. The mapping was defined in the provider, so I cannot easily remove the field.

I tried:

       <attribute-override name="rawShortDescription">
            <field />
        </attribute-override>

And it does not work.

The doctrine documentation says that there is no way to override a column type. Does this mean that I cannot delete the field?

Can I delete a field defined in a provider?
