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 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.
Added new server connection configuration setting connection_cursortype which allows modifying the default cursor type (using the new connection.cursortype
attribute value; see mxODBC Connect 2.0.3) without
having to modify the client side applications. The setting can be
applied on a per connection basis for enhanced flexibility.
The mxODBC DataDirect subpackage is now built against the current DataDirect ODBC manager version 7.1.2.
Fixed a problem with the .warningformat attribute not working as expected on cursors and connections.
MS SQL Server performance can be much enhanced,
and increased to levels beyond that of mxODBC Connect 2.0.2 and
releases, by adjusting the default cursor type to forward-only cursors
instead of static cursors. mxODBC Connect 2.0.4 makes this possible
without having to change client side applications by modifying the
server-config.ini file as follows:
[Connection_Example] ... # Use the faster forward-only cursors on this connection connection_cursortype = SQL.CURSOR_FORWARD_ONLY
The performance increase compared to mxODBC Connect 2.0.2 is enormous: from 2-3x faster executes/fetches for average queries, up to 300x faster for simple cases.
In mxODBC Connect 2.1, we will switch to using forward-only cursors per default for all database backends.
IBM DB2 can benefit from the same performance enhancements using forward-only cursors.
The effect is a lot smaller, but still noticeable: up to 2x faster executes/fetches with forward-only cursors, compared to mxODBC Connect 2.0.2.
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()
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.
mxODBC Connect Client now integrates directly with gevent, allowing client applications to run asynchronous tasks while performing remote database queries.
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.
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.
