Huh? ODBC is officially dead? Someone might want to let Microsoft know that:
Microsoft is Aligning with ODBC for Native Relational Data Access
From the above link:
ODBC is the de-facto industry standard for native relational data access...
and
The commercial release of Microsoft SQL Server, codename 'Denali' will be the last release to support OLE DB.
and finally,
"We encourage you to adopt ODBC in the development of your new and future versions of your application. You don’t need to change your existing applications using OLE DB, as they will continue to be supported on Denali throughout its lifecycle. While this gives you a large window of opportunity for changing your applications before the deprecation goes into effect, you may want to consider migrating those applications to ODBC as a part of your future roadmap. Microsoft is fully committed to making this transition as smooth and easy as possible.""
(emphasis added)
ODBC is useful for times when the underlying database might change but you don't want your code to (assuming the SQL stays the same across technologies). You could connect to an Oracle database one day and switch out to a SQL server database the next. The disadvantage is that you don't get the optimizations that having specific drivers affords you. The SQL Server Native client driver has been proven to be much faster than just using a standard ODBC driver.
