IOpenRowset is a required interface on the session. It can be supported by providers that do not support creating rowsets through commands.

The IOpenRowset model enables consumers to open and work directly with individual tables or indexes in a data store by using IOpenRowset::OpenRowset, which generates a rowset of all rows in the table or index.
