Python ODBC Database Interface
mxODBC is our commercially supported Python extension providing ODBC database connectivity to Python applications on Windows, Mac OS X, Unix and BSD platforms
This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/eGenix-mxODBC-3.2.0-GA.html
mxODBC provides an easy-to-use, high-performance, reliable and robust Python interface to ODBC compatible databases such as MS SQL Server, MS Access, Oracle Database, IBM DB2 and Informix , Sybase ASE and Sybase Anywhere, MySQL, 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 3.2.0 release of our mxODBC is a new release of our popular Python ODBC Interface for Windows, Linux, Mac OS X and FreeBSD.
New Features in 3.2 -------------------
* Switched to unixODBC 2.3.1+ API: mxODBC is now compiled against unixODBC 2.3.1, which finally removes the problems with the ABI change between 2.2 and 2.3 by switching to a new library version (libodbc.so.2).
* mxODBC connection objects can now be used as context managers to implicitly commit/rollback transactions.
* mxODBC cursor objects can now be used as context managers to implicitly close the cursor when leaving the block (regardless of whether an exception was raised or not)
* mxODBC added support for adjustable .paramstyles. Both 'qmark' (default) and 'named' styles are supported and can be set on connections and cursors. The 'named' style allows easier porting of e.g. Oracle native interface code to mxODBC.
* mxODBC now supports a writable connection.autocommit attribute to easily turn on/off the connection's auto commit mode.
* mxODBC added support for adjustable TIMESTAMP precision via the new connection/cursor.timestampresolution attribute.
* mxODBC will round to nearest nanosecond fraction instead of truncating the value. This will result in fewer conversion errors due to floating point second values.
* mxODBC's connect APIs Connect() and DriverConnect() support setting connection options prior to connecting to the database via a new connection_options parameter. This allows enabling e.g. the MARS feature in SQL Server Native Client.
* The connection.cursor() constructor now has a new cursor_options parameters which allows configuring the cursor with a set of cursor options.
* The .scroll() method supports far more ODBC drivers than before.
* Updated the SQL lookup object to include more ODBC SQL parameter codes, including special ones for SQL Server and IBM DB2.
* mx.ODBC.Manager will now prefer unixODBC over iODBC. Previous mxODBC releases used the order iODBC, unixODBC, DataDirect when looking for a suitable ODBC manager on Unix platforms. unixODBC is more widely supported nowadays and provides better Unicode support than iODBC.

Driver Compatibility Enhancements ---------------------------------
* Added work-around for Oracle Instance Client to prevent use of direct execution. cursor.executedirect() will still work, but won't actually use direct execution with the Oracle driver.
* Added work-around for Oracle Instant Client to prevent segfaults in the driver when querying the cursor.rowcount or cursor.rownumber.
* Added check to make sure that Python type binding mode is not used with Oracle Instance Client as this can cause segfaults with the driver and generally doesn't work.
* Added a work-around to have the IBM DB2 driver return correct .rowcount values.
* Improved Sybase ASE driver compatibility: this only supports Python type binding, which is now enabled per default.
* Added work-around for PostgreSQL driver, which doesn't support scrollable cursors.
* Add support for MS SQL Server ODBC Driver 1.0 for Linux to mxODBC
* Improved compatibility of the mxODBC native Unicode string format handling with Unix ODBC drivers when running UCS4 builds of Python.
* mxODBC 3.2 now always uses direct execution with the FreeTDS ODBC driver. This results in better compatibility with SQL Server and faster execution across the board.
* Add work-around to have FreeTDS work with 64-bit integers outside the 32-bit signed integer range.
* FreeTDS' .rowcount attribute gave misleading values for SELECTs. This now always returns -1 (until they hopefully fix the driver to return usable data).

mxODBC Editions ---------------
mxODBC is available in these three editions:
* The low-cost Standard Edition which provides data connectivity to a single database type, e.g. just MS SQL Server.
* The Professional Edition, which gives full access to all mxODBC features.
* The Product Development Edition, which allows including mxODBC in applications you develop.
Compared to mxODBC 3.0, we have simplified our license terms to clarify the situation on multi-core and virtual machines. In most cases, you no longer need to purchase more than one license per processor or virtual machine, scaling down the overall license costs significantly compared to earlier mxODBC releases.
For a complete overview of the new editions, please see the product page.
