Wrapped OLEDB Interfaces in OleDBPro

        OleDBPro encapsulates all of defined OLEDB objects except TEnumerator. OleDBPro does wrap most of defined OLEDB interfaces but not all. The interfaces, which are either often used or complicate to be used with applications development, are wrapped in the OleDBPro module.  In other words, the excluded interfaces are simple to use and not often employed with various software development. If you need them, you can easily extend a class or template with your needed interfaces.

        The following lists the interfaces wrapped in OleDBPro and grouped by OLEDB objects.
