Using the CData ODBC Driver for OData in PyCharm

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

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 OData 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 OData 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 OData

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.

The User and Password properties, under the Authentication section, must be set to valid OData user credentials. In addition, you will need to specify a URL to a valid OData server organization root or OData services file.

Below is the syntax for a DSN:

[CData OData Source] Driver = CData ODBC Driver for OData Description = My Description URL = http://services.odata.org/V4/Northwind/Northwind.svc UseIdUrl = True OData Version = 4.0 Data Format = ATOM

Execute SQL to OData

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 OData};URL = http://services.odata.org/V4/Northwind/Northwind.svc;UseIdUrl = True;OData Version = 4.0;Data Format = ATOM;') 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 OData in PyCharm using the CData ODBC Driver, you will be able to build Python apps with access to OData services 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.
