============= django-pyodbc

A Django MS SQL Server external DB backend that uses ODBC by employing the pyodbc library. It supports SQL Server 2000 and 2005.

.. _Django: http://djangoproject.com/ .. _pyodbc: http://pyodbc.sourceforge.net

Features

Dependencies

Installation

  1. Install pyodbc.

  2. Add the directory where you have copied the project files to your Python path. So, for example, if you have the following directory structure::

    /home/user/src/django-pyodbc
        |
        +- sql_server
              |
              +- pyodbc

    you should add /home/user/src/django-pyodbc to you Python module search path. One way to do this is setting the PYTHONPATH environment variable::

    $ export PYTHONPATH=/home/user/src/django-pyodbc

  3. Now you can point the DATABASE_ENGINE setting in the settings file used by your Django application or project to the 'sql_server.pyodbc' module path::

    DATABASE_ENGINE='sql_server.pyodbc'

Configuration

The following settings control the behavior of the backend:

Standard Django settings

DATABASE_NAME String. Database name. Required.

DATABASE_HOST String. SQL Server instance in "server\instance" format.

DATABASE_PORT String. Server instance port.

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

DATABASE_PASSWORD String. Database user password.

DATABASE_OPTIONS Dictionary. Current available keys are:

``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
``DATABASE_ODBC_DRIVER`` to ``"SQL Native Client"``). See
    http://msdn.microsoft.com/en-us/library/ms131686.aspx.
    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 ``DATABASE_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 http://freetds.org/userguide/dsnless.htm for more information.

django-pyodbc-specific settings

DATABASE_ODBC_DSN String. A named DSN can be used instead of DATABASE_HOST.

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

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

DATABASE_COLLATION String. Name of the collation to use when performing text field lookups against the database. Default value is "Latin1_General_CI_AS". For Chinese language you can set it to "Chinese_PRC_CI_AS".
