64-bit OLEDB Provider for ODBC (MSDASQL) Available in Longhorn Server, Starting Beta 3

 

We’re pleased to announce that Longhorn Server Beta 3 will include a 64-bit version of MSDASQL, Microsoft’s OLEDB Provider for ODBC.

What is MSDASQL?

MSDASQL is an OLEDB provider that allows applications built on OLEDB and ADO (which uses OLEDB internally) to access data sources through an ODBC driver instead of a database. MSDASQL ships with the Windows Operating System, and Longhorn Beta 3 is the first Windows release to include a 64-bit version of MSDASQL.

Who does this impact?

If you are a customer in one of the following scenarios, you will see direct benefits from this technology when upgrading to or deploying Longhorn Server:

· SQL Server Customers with Heterogeneous DBMS Environments: the Linked Server and Distributed Query features of SQL Server connect to external data sources through an OLEDB provider. The addition of the 64-bit MSDASQL Provider allows these features to leverage the 64-bit equivalents of ODBC drivers that SQL Server applications of 32-bit environments are already using, and to use an ODBC 64-bit driver if a 64-bit OLEDB provider for the target external data source is not available.

· ADO and ASP Customers Planning a Migration to 64-bit: on 32-bit operating systems, MSDASQL is the default OLEDB provider used by ADO. In Longhorn Server Beta 3, applications that specify an ODBC driver in the connection string (e.g. “Driver={SQL Server}...”) are not required to change connection strings when migrating to 64-bit.

· Customers with OLEDB Applications Using ODBC Data Sources: when migrating these applications to 64-bit, the applications can leverage a native 64-bit ODBC driver, provided that one is available for the target data source.

Isn’t MSDASQL Deprecated?

Previous messaging on MSDN indicated that a 64-bit version of MSDASQL would not be available. However, we have received numerous requests from customers for this technology and we are making it available to address the pain experienced in the scenarios described above without 64-bit MSDASQL.

    Excellent! I hope this driver will be available for Windows 2003 Server as well! We have to import data from Excel and this functionality is very important for us. We have moved to 64-bit and now we need a 32-bit server to select from the excel-file and into a table on the 64-bit server. Espen Antonsen System Developer 24SevenOffice

    This great news.  We have been really stressed.  We need to be able to import data from an HP NonStop to our SQL Server data warehouse.   We too would like to have MSDASQL available for Windows 2003 Server.  The sooner the better!

    This is great news but is there going to be a MSDASQL release for Server 2003?? As most people who fall into the "numerous requests" seem to be running this os.

    We could use this also in our win 2003 x64 now. Could you advise if it is or is not avail as a separate download or can we get it from the Longhorn beta, or advise if its not compatabile with win 2003 x64? At least I'll know if I need tell my boss we need to get a workaround... thanks! "Hi, is this available to download as a seperate install?

    There is an installer for Itanium, but I didn't found a x64t OLEDB Provider for ODBC. Does any body found it?

    I too am desperate for a 64Bit OLE DB to ODBC driver. I am assuming that it will only access 64bit to 64 bit or will it be able to address 32bit ODBC System DSNs as well?

    Where can I download this 64-bit OLEDB Provider for ODBC?  Windows Server 2008 has now been released so I would assume that Longhorn Beta 3 is long gone and therefore this OLEDB driver should be available. HELP!

    Can someone post a link here where I can download the update for Windows 2003 which will included the 64-bit MSDASQL? And also, if anyone has an anticipated release timeframe, that would be helpful too.  The last estimate I received was by the end of March... Thanks!

    I was wondering about the licensing requirements on the 64 bit msdasql.dll Can this be distributed with a non-microsoft product that runs on windows? Where can I find the license agreement that would clearly state whether the above is allowed or not. I have tried looking at the license agreement of the hotfix itself but says that it is a supplement to windows and that is not conclusive. Any pointer would be helpful
