[url=http://social.technet.microsoft.com/Forums/en/sqldataaccess/thread/e696d0ac-f8e2-4b19-8a08-7a357d3d780f]Here's another link[/url] which discusses the topic.[/quote]That was actually interesting link to read. Especially the part about [quote]Microsoft has been supporting ODBC through all the releases of SQL Server for relational data access. This includes adding new functionality to the ODBC drivers whenever a corresponding feature is added to SQL Server.[/quote]I've developed an application few years ago, which needed to receive and display in GUI long stored procedure progress. Progress messages were implemented in stored proc using RAISERROR (of message severity) WITH NOWAIT which allows receiving such messages asynchronously by the client. It is possible using ADO InfoMessage handling. But, I only managed to get it working properly using ODBC driver! All other drivers, for some reason, would get all InfoMessage events accumulated and raised at once on the end of process. I was really surprised that time why "old" ODBC driver did work but newest SQL Server Native Client didn't...Looks like MS always treated ODBC as the most up-to-date driver.Tue, 09 Oct 2012 04:49:37 GMTEugene Elutinhttp://www.sqlservercentral.com/Forums/Topic537592-338-1.aspx[quote][b]Steve Jones - SSC Editor (7/28/2008)[/b][hr]Good explanation.

As per the below article, Microsoft is planning to depreciate OLEDB APIs and SQL Server 2012 will be the last version to support OLEDB. Therefore, it is highly recommended for programmers to write their codes with ODBC compatibility than OLEDB.http://www.itwriting.com/blog/4825-full-circle-for-microsoft-database-apis-as-ole-db-for-sql-server-is-deprecated.htmlMon, 08 Oct 2012 08:11:18 GMTyidnek T Beyenehttp://www.sqlservercentral.com/Forums/Topic537592-338-1.aspxGood explanation.

OLE DB allows SQL Server to link to these nonrelational database systems. For instance, if you want to query, through SQL Server, the Active Directory on the domain controller, you couldn't do this with ODBC, because it's not a relational database. However, you could use an OLE DB provider to accomplish that.In summary, The key difference between OLE DB and ODBC is that OLE DB can provide connection to data stored in non-relational format.:)Mon, 28 Jul 2008 09:33:33 GMTNayyarhttp://www.sqlservercentral.com/Forums/Topic537592-338-1.aspxHi Friendswhat is the difference between ODBC and OleDB?Mon, 21 Jul 2008 05:53:25 GMTsteven-733381
