IBM DB2 Icon 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.

Using the CData ODBC Driver for DB2 in PyCharm


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.

Set the following properties to connect to DB2:

  • Server: Set this to the name of the server running DB2.
  • Port: Set this to the port the DB2 server is listening on.
  • Database: Set this to the name of the DB2 database.
  • User: Set this to the username of a user allowed to access the database.
  • Password: Set this to the password of a user allowed to access the database.

You will also need to install the corresponding DB2 driver:

  • Windows: Install the IBM Data Server Provider for .NET.

    On Windows, installing the IBM Data Server Provider is sufficient, as the installation registers it in the machine.config.

  • Java: Install the IBM Data Server Driver for JDBC.

    In the Java version, place the IBM Data Server Driver JAR in the www\WEB-INF\lib\ folder for this application.

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.
