SQL Server Native Client

Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Analytics Platform System (PDW)

SQL Server Native Client, also known as SNAC or SQLNCLI, refers to the ODBC and OLE DB drivers for SQL Server, prior to SQL Server 2022 (16.x).


The SQL Server Native Client (often abbreviated SNAC) has been removed from SQL Server 2022 (16.x) and SQL Server Management Studio 19 (SSMS). The SQL Server Native Client (SQLNCLI or SQLNCLI11) and the legacy Microsoft OLE DB Provider for SQL Server (SQLOLEDB) are not recommended for new application development. Switch to the new Microsoft OLE DB Driver (MSOLEDBSQL) for SQL Server or the latest Microsoft ODBC Driver for SQL Server going forward. For SQLNCLI that ships as a component of SQL Server Database Engine (versions 2012 through 2019), see this Support Lifecycle exception.


For more information and to download the SNAC or ODBC Drivers, see the SNAC lifecycle explained blog post. For more information on ODBC Driver for SQL Server, see Microsoft ODBC Driver for SQL Server.
