django-pyodbc 0.3.0

Django 1.5 SQL Server backend using pyodbc.

django-pyodbc is a Django SQL Server DB backend powered by the pyodbc library. pyodbc is a mature, viable way to access SQL Server from Python in multiple platforms and is actively maintained. It’s also used by SQLAlchemy for SQL Server connections.

This is a fork of the original django-pyodbc, hosted on Google Code and last updated in 2011.


  • Support for Django 1.4 and up.
  • Support for SQL Server 2000, 2005, 2008, and 2012 (please let us know if you have success running this backend with another version of SQL Server)
  • Native Unicode support. Every string that goes in is stored as Unicode, and every string that goes out of the database is returned as Unicode. No conversion to/from intermediate encodings takes place, so things like max_length in CharField works just like expected.
  • Both Windows Authentication (Integrated Security) and SQL Server Authentication.
  • LIMIT+OFFSET and offset w/o LIMIT emulation under SQL Server 2005.
  • LIMIT+OFFSET under SQL Server 2000.
  • Django’s TextField both under SQL Server 2000 and 2005.
  • Passes most of the tests of the Django test suite.
  • Compatible with SQL Server and SQL Server Native Client from Microsoft (Windows) and FreeTDS ODBC drivers (Linux).



  1. Install django-pyodbc.

    pip install django-pyodbc
  2. Now you can now add a database to your settings using standard ODBC parameters.

       'default': {
           'ENGINE': "django_pyodbc",
           'HOST': ",1433",
           'USER': "mssql_user",
           'PASSWORD': "mssql_password",
           'NAME': "database_name",
           'OPTIONS': {
               'host_is_server': True
  3. That’s it! You’re done.


The following settings control the behavior of the backend:

Standard Django settings

NAME String. Database name. Required.

HOST String. SQL Server instance in server\instance or ip,port format.

USER String. Database user name. If not given then MS Integrated Security
will be used.

PASSWORD String. Database user password.

OPTIONS Dictionary. Current available keys:

  • driver

    String. ODBC Driver to use. Default is "SQL Server" on Windows and "FreeTDS" on other platforms.

  • dsn

    String. A named DSN can be used instead of HOST.

  • autocommit

    Boolean. Indicates if pyodbc should direct the the ODBC driver to activate the autocommit feature. Default value is False.

  • MARS_Connection

    Boolean. Only relevant when running on Windows and with SQL Server 2005 or later through MS SQL Server Native client driver (i.e. setting driver to "SQL Server Native Client 11.0"). See Default value is False.

  • host_is_server

    Boolean. Only relevant if using the FreeTDS ODBC driver under Unix/Linux.

    By default, when using the FreeTDS ODBC driver the value specified in the HOST setting is used in a SERVERNAME ODBC connection string component instead of being used in a SERVER component; this means that this value should be the name of a dataserver definition present in the freetds.conf FreeTDS configuration file instead of a hostname or an IP address.

    But if this option is present and it’s value is True, this special behavior is turned off.

    See for more information.

  • extra_params

    String. Additional parameters for the ODBC connection. The format is "param=value;param=value".

  • collation

    String. Name of the collation to use when performing text field lookups against the database. For Chinese language you can set it to "Chinese_PRC_CI_AS". The default collation for the database will be used if no value is specified.

  • encoding

    String. Encoding used to decode data from this database. Default is ‘utf-8’.

  • driver_needs_utf8

    Boolean. Some drivers (FreeTDS, and other ODBC drivers?) don’t support Unicode yet, so SQL clauses’ encoding is forced to utf-8 for those cases.

    If this option is not present, the value is guessed according to the driver set.

  • limit_table_list

    Boolean. This will restrict the table list query to the dbo schema.


To run the test suite:

python tests/ --settings=test_django_pyodbc
