eGenix mxODBC Connect 2.1.3 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 database drivers for all the platforms you target with your Python application.
Instead you use an easy to install royalty-free 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.

News
mxODBC Connect 2.1.3 is a patch level release of our successful mxODBC Connect database product. It includes these enhancements and fixes:
Security Enhancements
- Updated included OpenSSL libraries to 1.0.1m. See https://www.openssl.org/news/secadv_20150319.txt for a complete list of changes. Among other security fixes, this addresses the FREAK Attack (CVE-2015-0204).
- Upgraded default RSA key length for demo certificates to 2048 bits.
mxODBC Connect Enhancements
- Upgraded eGenix PyRun used for mxODBC Connect Server on Linux to 2.1.0.
- Upgraded the Python version used for mxODBC Connect Server to 2.7.9.
- Fixed a bug causing pip uninstall not to remove .pyc/.pyo files
- Resolved an intermittent error related to hash seeds which sometimes caused prebuilt archives to not install correctly. Thanks to Albert-Jan Roskam for reporting this.
mxODBC API Enhancements
- Upgraded the mxODBC Connect Server to mxODBC 3.3.2.
MS SQL Server
- Fixed an "ODBC driver sent negative string size" error when using empty
strings or None with output parameters for SQL Server
ODBC drivers.
- Clarified that due to the way the SQL Server ODBC driver sends data, mixing output parameters and output result sets is not possible. A work-around for this is to send back output parameters as additional result set.
SAP Sybase ASE
- Added a work-around for the Sybase ASE ODBC driver which has problems with BIGINT columns. These are now supported.
- Fixed a possible "ODBC driver sent negative string size" error when using empty strings or None with output parameters for Sybase ASE ODBC drivers.
Fixes
- Fixed the handling of None as default value for output parameters in e.g. stored procedures to use VARCHAR binding rather than CHAR binding. The latter caused padding with some database backends.
- Changed cursor.colcount to be determined on-demand rather than right after the prepare step of statement execution.
For the full set of changes, including those of the 2.1 series of mxODBC Connect, please check the mxODBC Connect change log.
Features
The mxODBC Connect 2.1 series was announced on 2014-05-28. These are the highlights of the new release:
Stored Procedures
- mxODBC Connect now has full support for input, output and input/output parameters in stored procedures and stored functions, allowing easy integration with existing databases systems.
User Customizable Row Objects
- Support for user customizable row objects by adding cursor/connection .rowfactory and .row constructor attributes. When set, these are used to wrap the normal row tuples returned by the .fetch*() methods into dynamically created row objects.
- New RowFactory classes to support cursor.rowfactory and cursor.row. These allow dynamically creating row classes that provide sequence as well as mapping and attribute access to row fields - similar to what namedtuples implements, but more efficient and specific to result sets.
Asynchronous Processing
- Compatible with the latest gevent and greenlet packages. mxODBC Connect Client will happily work together with the asynchronous libraries gevent. All it takes is a single configuration entry in the client side config file.
Upgrading
You are encouraged to upgrade to this latest mxODBC Connect release. When upgrading, please always upgrade both the server and the client installations to the same version - even for patch level releases.
