IBM DB2 ODBC Driver

The IBM DB2 ODBC Driver is a powerful tool that allows you to connect with live data from IBM DB2, directly from any applications that support ODBC connectivity.

Access IBM DB2 data like you would a database - read, write, and update through a standard ODBC Driver interface.



Connect to DB2 as an ODBC data source in PyCharm using the CData ODBC Driver for DB2.

The CData ODBC Drivers can be used in any environment that supports loading an ODBC Driver. In this tutorial we will explore using the CData ODBC Driver for DB2 from within PyCharm. Included are steps for adding the CData ODBC Driver as a data source, as well as basic PyCharm code to query the data source and display results.

To begin, this tutorial will assume that you have already installed the CData ODBC Driver for DB2 as well as PyCharm.

Add Pyodbc to the Project

Follow the steps below to add the pyodbc module to your project.

  1. Click File -> Settings to open the project settings window.
  2. Click Project Interpreter from the Project: YourProjectName menu.
  3. To add pyodbc, click the + button and enter pyodbc.
  4. Click Install Package to install pyodbc.

Connect to DB2

You can now connect with an ODBC connection string or a DSN. See the Getting Started section in the CData driver documentation for a guide to creating a DSN on your OS.

Below is the syntax for a DSN:

[CData DB2 Source] Driver = CData ODBC Driver for DB2 Description = My Description Server = 10.0.1.2 Port = 50000 User = admin Password = admin Database = test

Execute SQL to DB2

Instantiate a Cursor and use the execute method of the Cursor class to execute any SQL statement.

import pyodbc cnxn = pyodbc.connect('DRIVER={CData ODBC Driver for DB2};Server = 10.0.1.2;Port = 50000;User = admin;Password = admin;Database = test;') cursor = cnxn.cursor() cursor.execute("SELECT OrderName, Freight FROM Orders WHERE ShipCity = 'New York'") rows = cursor.fetchall() for row in rows: print(row.OrderName, row.Freight)

After connecting to DB2 in PyCharm using the CData ODBC Driver, you will be able to build Python apps with access to DB2 data as if it were a standard database. If you have any questions, comments, or feedback regarding this tutorial, please contact us at support@cdata.com.
