cfletcher1856 / django-pyodbc

Fork of django-pyodbc (from https://code.google.com/p/django-pyodbc/) that adds a cleaner project structure and Django 1.5 support.

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.

Features

• Supports LIMIT+OFFSET and offset w/o LIMIT emulation under SS2005.
• Supports LIMIT+OFFSET under SS2000.
• Transparently supports Django's TextField both under SS2000 and SS2005.
• 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).

Installation

1. Install django-pyodbc.

    pip install django-pyodbc
   

2. Now you can now add a database to your settings using standard ODBC parameters.

   DATABASES = {
      'default': {
          'ENGINE': "django_pyodbc",
          'HOST': "127.0.0.1,1433",
          'USER': "mssql_user",
          'PASSWORD': "mssql_password",
          'NAME': "database_name",
          'OPTIONS': {
              'host_is_server': True
          },
      }
   }

3. That's all!

Configuration

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 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 ``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

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

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

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. Default value is "Latin1_General_CI_AS". For Chinese language you can set it to "Chinese_PRC_CI_AS".
