                   Python ODBC Database Interface

                           Version 3.3.2

    mxODBC is our commercially supported Python extension providing
         ODBC database connectivity to Python applications
            on Windows, Mac OS X, Unix and BSD platforms
           with many advanced Python DB-API extensions and
                 full support of stored procedures

This announcement is also available on our web-site for online reading:



mxODBC provides an easy-to-use, high-performance, reliable and robust
Python interface to ODBC compatible databases such as MS SQL Server,
Oracle Database, IBM DB2, Informix and Netezza, SAP Sybase ASE and
Sybase Anywhere, Teradata, MySQL, MariaDB, PostgreSQL, SAP MaxDB and
many more:


The "eGenix mxODBC - Python ODBC Database Interface" product is a
commercial extension to our open-source eGenix mx Base Distribution:




The 3.3.2 release of our mxODBC is a patch level release of our
popular Python ODBC Interface for Windows, Linux, Mac OS X and
FreeBSD. It includes these enhancements and fixes:

Driver Compatibility

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

 * 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.


 * 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.

 * Fixed an issue with mxODBC triggering unwanted ODBC errors after
   the prepare step when calling a stored procedure. These were not
   reported, but do show up in the ODBC log.

 * Fixed some minor issues with the package web installer.

For the full set of changes please check the mxODBC change log:
