Overview

This RFC is for changing the behavior of GetCapabilitiesX().

Motivation

There are cases where a provider indicates support of a capability that is actually not supported by a data store the provider may connect to. For example, if an Oracle data store is not prepared for locking, this functionality is not supported in that data store although the provider itself is capable of providing the functionality. ODBC also can connect to a variety of sources, each with varying levels of capability.

Proposed Solution

Change the behavior of GetCapabilities. On an open connection it will retrieve the exact capabilities, specific for that database. On a closed connection the current behavior will be preserved and provider level capaabilities will be returned to the caller.
