eGenix mxODBC Connect 2.0.1 GA
Introduction
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 application.
Instead you use an easy to install Python client library which connects directly to the mxODBC Connect database server over the network.
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.

API Enhancements

- Added a work-around to prevent truncation warnings with the SQL Server ODBC driver when using .executemany(..., direct=1). Thanks for Michael Bayer.
Server Enhancements

Client Enhancements

mxODBC Connect 2.0.0 was released on 2012-08-20. These are the highlights of the new release:
Enhanced API
- 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 1.0.
- mxODBC Connect Client comes with all the mxODBC enhancements, including:
- connection and cursor objects can be used as context managers
- adjustable parameter styles (qmark or named)
- connection .autocommit attribute to easily switch on autocommit
- adjustable timestamp resolution
- new possibilities to set connection and cursor options to adjust the ODBC objects to your application needs, e.g. set a connection read-only or set a query timeout
- adjustable decimal, datetime and string formats
- adjustable warning format to be able to handle server warnings without client interaction
- greatly improved result set scrolling support
- Unicode support for all catalog methods
- Access to additional result set meta data via cursor.getcolattribute()
Updated Compatibility
- The server now features all the ODBC driver compatibility enhancements provided by mxODBC 3.2, including improved and updated support for MS SQL Server Native Client, Oracle Instant Client, Sybase ASE, IBM DB2, Teradata and Netezza.
- Native Windows x64 builds with signed executables and a tray app rewritten in C are available for Windows 2008R2, Vista and 7 x64, so you can benefit from better performance, fewer UAC dialogs and smaller memory footprint.
Asynchronous Execution
- mxODBC Connect Client now integrates directly with gevent, allowing client applications to run asynchronous tasks while performing remote database queries.
Better Integration
- mxODBC Connect now uses the official IANA registered port 6632 for both plain text and SSL-encrypted communication.
- mxODBC Connect Client now allows selecting the used SSL module from two available options: Python standard lib ssl module and pyOpenSSL.
