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
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.
Fixed an "ODBC driver sent negative string size" error when using empty
strings or None with output parameters for SQL Server
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
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
For the full set of changes, including those of the 2.1 series of mxODBC Connect, please check the mxODBC Connect change log.
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.
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.
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.
