pymssql

A simple database interface for Python that builds on top of FreeTDS to provide a Python DB-API (PEP-249) interface to Microsoft SQL Server.

The 2.x branch of pymssql is built on the latest release of FreeTDS which removes many of the limitations found with older FreeTDS versions and the 1.x branch.
