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 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.
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.
The 2.0.3 release of mxODBC Connect includes the following enhancements and fixes:
# Connect to the remote database
from mx.ODBCConnect.Client import ServerSession
session = ServerSession(...)
ODBC = session.open()
connection = ODBC.DriverConnect(...)
# Use the faster forward-only cursors
connection.cursortype = ODBC.SQL.CURSOR_FORWARD_ONLY
# Cursors created on this connection will then default
# to forward only cursors
cursor = connection.cursor()
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.
The effect is a lot smaller compared to MS SQL Server, but still noticeable: up to 2x faster executes/fetches with forward-only cursors, compared to mxODBC Connect 2.0.2.
Due to popular demand, we have added an unlimited connections server license, so now you can choose between:
