Python ODBC Database Interface
mxODBC Connect is our commercially supported client-server product for
connecting Python applications to relational databases
in a truly platform independent way.
This announcement is also available on our web-site for online reading:
The mxODBC Connect Database Interface for Python allows users to
easily connect Python applications to all major databases on the
market today in a highly portable, convenient and secure way.
Python Database Connectivity the Easy Way
Unlike our mxODBC Python extension, mxODBC Connect is designed as
client-server application, so you no longer need to find production
quality ODBC drivers for all the platforms you target with your Python
Instead you use an easy to install royalty-free Python client library
which connects directly to the mxODBC Connect database server over the
This makes mxODBC Connect a great basis for writing cross-platform
multi-tier database applications and utilities in Python, especially
if you run applications that need to communicate with databases such
as MS SQL Server and MS Access, Oracle Database, IBM DB2 and Informix,
Sybase ASE and Sybase Anywhere, MySQL, PostgreSQL, SAP MaxDB and many
more, that run on Windows or Linux machines.
Ideal for Database Driven Client Applications
By removing the need to install and configure ODBC drivers on the
client side and dealing with complicated network setups for each set
of drivers, mxODBC Connect greatly simplifies deployment of database
driven client applications, while at the same time making the network
communication between client and database server more efficient and

page, in particular, the full list of available features.

The 2.0.4 release of mxODBC Connect includes the following
enhancements and fixes:
* Upgraded client and server to the most recent eGenix pyOpenSSL
Distribution 0.13.3.1.0.1.6. See http://egenix.com/go52 for
* Authentication errors are now reported with the SYSTEM_ERROR log
level, making them visible using the default server side log level
* Updated the server to use eGenix mxODBC 3.2.3 for database
connectivity. See http://egenix.com/go45 for details.
* Added new server connection configuration setting
connection_cursortype which allows modifying the default cursor
type (using the new connection.cursortype attribute value; see
http://egenix.com/go42) without having to modify the client side
applications. The setting can be applied on a per connection basis
for enhanced flexibility.
* The mxODBC DataDirect subpackage is now built against the current
DataDirect ODBC manager version 7.1.2.
* Fixed a problem with the .warningformat attribute not working as
expected on cursors and connections.
* MS SQL Server performance can be much enhanced, and increased to
levels beyond that of mxODBC Connect 2.0.2 and previous releases,
by adjusting the default cursor type to forward-only cursors
instead of static cursors.
mxODBC Connect 2.0.4 makes this possible without having to change
client side applications by modifying the server-config.ini file as
# Use the faster forward-only cursors on this connection
connection_cursortype = SQL.CURSOR_FORWARD_ONLY
The performance increase compared to mxODBC Connect 2.0.2 is
enormous: from 2-3x faster executes/fetches for average queries, up
to 300x faster for simple cases.
In mxODBC Connect 2.1, we will switch to using forward-only cursors
per default for all database backends.
* IBM DB2 can benefit from the same performance enhancements using
The effect is a lot smaller, but still noticeable: up to 2x faster
executes/fetches with forward-only cursors, compared to mxODBC

mxODBC Connect 2.0 Highlights
mxODBC Connect 2.0 was released on 2012-08-20. These are the most
* mxODBC Connect Server now uses mxODBC 3.2 internally and makes its
API available in the mxODBC Connect Client. This is a major step
forward from the mxODBC 3.0 version used in mxODBC Connect Server
* We've added native Windows x64 builds.
* mxODBC Connect Client now integrates directly with gevent, allowing
client applications to run asynchronous tasks while performing
remote database queries.
