                    Python ODBC Database Interface

                            Version 2.0.4

 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
more secure.

For more information, please have a look at the mxODBC Connect product
page, in particular, the full list of available features.

For more information, please see the product page:




The 2.0.4 release of mxODBC Connect includes the following
enhancements and fixes:

Security Enhancements

 * Upgraded client and server to the most recent eGenix pyOpenSSL
   Distribution 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

Server Enhancements

 * 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.

Client Enhancements

 * Fixed a problem with the .warningformat attribute not working as
   expected on cursors and connections.

Performance Enhancements

 * 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
   forward-only cursors.

   The effect is a lot smaller, but still noticeable: up to 2x faster
   executes/fetches with forward-only cursors, compared to mxODBC
   Connect 2.0.2.

change log:


mxODBC Connect 2.0 Highlights

mxODBC Connect 2.0 was released on 2012-08-20. These are the most
important highlights:

 * 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.
