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.

Detailed information on pymssql is available on the website:

New development is happening on GitHub at:

There is a Google Group for discussion at:

Getting started

pymssql wheels are available from PyPi. To install it run:

.. code-block:: bash

pip install -U pip
pip install pymssql

Most of the times this should be all what's needed. The official pymssql wheels bundle a static copy of FreeTDS and have SSL support so they can be used to connect to Azure.

.. note:: On some Linux distributions pip version is too old to support all the flavors of manylinux wheels, so upgrading pip is necessary. An example of such distributions would be Ubuntu 18.04 or Python3.6 module in RHEL8 and CentOS8.

Basic example

.. code-block:: python

conn = pymssql.connect(server, user, password, "tempdb")
cursor = conn.cursor(as_dict=True)

cursor.execute('SELECT * FROM persons WHERE salesrep=%s', 'John Doe')
for row in cursor:
    print("ID=%d, Name=%s" % (row['id'], row['name']))

conn.close()
