BCD (binary coded decimal) support is not available. Key violation tables cannot be created with DbiAddIndex. (All other DbiAddIndex functionality is supported.) QBE, heterogeneous queries, and queries using the local SQL engine are not supported. In the SDK, DbiDoRestructure and DbiRegenIndex are not available. Opening a table when TTable.Exclusive is set to True prevents the user from opening that table again, even in same session.
