MySQL provides standards-based drivers for JDBC, ODBC, and .Net enabling developers to build database applications in their language of choice. In addition, a native C library allows developers to embed MySQL directly into their applications.

The OLE DB Driver for SQL Server is a stand-alone data access application programming interface (API), used for OLE DB, that was introduced in SQL Server 2005 (9.x). OLE DB Driver for SQL Server delivers the SQL OLE DB driver in one dynamic-link library (DLL). It also provides new functionality above and beyond that supplied by the Windows Data Access Components (Windows DAC, formerly Microsoft Data Access Components, or MDAC). The OLE DB Driver for SQL Server can be used to create new applications or enhance existing applications that need to take advantage of features introduced in SQL Server 2005 (9.x), such as multiple active result sets (MARS), user-defined data types (UDT), query notifications, snapshot isolation, and XML data type support.
Note
For a list of the differences between OLE DB Driver for SQL Server and Windows DAC, plus information about issues to consider before updating a Windows DAC application to OLE DB Driver for SQL Server, see Updating an Application to OLE DB Driver for SQL Server from MDAC.
Important
The previous Microsoft OLE DB Provider for SQL Server (SQLOLEDB) and SQL Server Native Client OLE DB provider (SQLNCLI) remains deprecated and it is not recommended to use either for new development work.
The OLE DB Driver for SQL Server can be used in conjunction with OLE DB Core Services supplied with Windows DAC, but this is not a requirement; the choice to use Core Services or not depends on the requirements of the individual application (for example, if connection pooling is required).
ActiveX Data Object (ADO) applications may use the OLE DB Driver for SQL Server, but it is recommended to use ADO in conjunction with the DataTypeCompatibility connection string keyword (or its corresponding DataSource property). When using the OLE DB Driver for SQL Server, ADO applications may exploit those new features introduced in SQL Server 2005 (9.x) that are available via the OLE DB Driver for SQL Server via connection string keywords or OLE DB properties or Transact-SQL. For more information about the use of these features with ADO, see Using ADO with OLE DB Driver for SQL Server.
OLE DB Driver for SQL Server was designed to provide a simplified method of gaining native data access to SQL Server using OLE DB. It provides a way to innovate and evolve new data access features without changing the current Windows DAC components, which are now part of the Microsoft Windows platform.
While OLE DB Driver for SQL Server uses components in Windows DAC, it is not explicitly dependent on a particular version of Windows DAC. You can use OLE DB Driver for SQL Server with the version of Windows DAC that is installed with any operating system supported by OLE DB Driver for SQL Server.
Different generations of OLE DB Drivers
There are three distinct generations of Microsoft OLE DB providers for SQL Server.
1. Microsoft OLE DB Provider for SQL Server (SQLOLEDB)
The Microsoft OLE DB Provider for SQL Server (SQLOLEDB) still ships as part of Windows Data Access Components. It is not maintained anymore and it is not recommended to use this driver for new development.
2. SQL Server Native Client (SNAC)
Starting in SQL Server 2005 (9.x), the SQL Server Native Client (SNAC) includes an OLE DB provider interface (SQLNCLI) and is the OLE DB provider that shipped with SQL Server 2005 (9.x) through SQL Server 2012 (11.x).
It was announced as deprecated in 2011 and it is not recommended to use this driver for new development. For more information about the SNAC lifecycle and available downloads, refer to SNAC lifecycle explained.
3. Microsoft OLE DB Driver for SQL Server (MSOLEDBSQL)
OLE DB was undeprecated and released in 2018.
The new OLE DB provider is called the Microsoft OLE DB Driver for SQL Server (MSOLEDBSQL). The new provider will be updated with the most recent server features going forward.
Note
To use the new Microsoft OLE DB Driver for SQL Server in existing applications, you should plan to convert your connection strings from SQLOLEDB or SQLNCLI, to MSOLEDBSQL.
