Using the CData ODBC Driver for Demio in PyCharm

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 Demio 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 Demio 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 Demio

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.

Start by setting the Profile connection property to the location of the Demio Profile on disk (e.g. C:\profiles\Demio.apip). Next, set the ProfileSettings connection property to the connection string for Demio (see below).

Demio API Profile Settings

Navigate to Account Settings > API in your Demio account (Owner access required) to obtain your API Key and API Secret.

Below is the syntax for a DSN:

[CData API Source]
Driver = CData ODBC Driver for Demio
Description = My Description
Profile = C:\profiles\Demio.apip
ProfileSettings = 'APIKey = your_api_key
APISecret = your_api_secret'

Execute SQL to Demio

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 API};Profile = C:\profiles\Demio.apip;ProfileSettings = 'APIKey = your_api_key;APISecret = your_api_secret';')
cursor = cnxn.cursor()
cursor.execute("SELECT Id, Name FROM Event WHERE Automated = 'true'")
rows = cursor.fetchall()
for row in rows:
  print(row.Id, row.Name)

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