OLE DB プロイバイダの提供はDenaliが最後

The next release of Microsoft SQL Server, codename “Denali”, will be the last release to support OLE DB. OLE DB will be supported for 7 years from launch, the life of Denali support, to allow you a large window of opportunity for changing your applications before the deprecation. This deprecation applies to the Microsoft SQL Server OLE DB provider only. Other OLE DB providers as well as the OLE DB standard will continue to be supported until explicitly announced.
