Using the CData ODBC Driver for HubDB in PyCharm


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

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 HubDB 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 HubDB 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 HubDB

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.

There are two authentication methods available for connecting to HubDB data source: OAuth Authentication with a public HubSpot application and authentication with a Private application token.

Using a Custom OAuth App

AuthScheme must be set to "OAuth" in all OAuth flows. Be sure to review the Help documentation for the required connection properties for you specific authentication needs (desktop applications, web applications, and headless machines).

Follow the steps below to register an application and obtain the OAuth client credentials:

  1. Log into your HubSpot app developer account.
    • Note that it must be an app developer account. Standard HubSpot accounts cannot create public apps.
  2. On the developer account home page, click the Apps tab.
  3. Click Create app.
  4. On the App info tab, enter and optionally modify values that are displayed to users when they connect. These values include the public application name, application logo, and a description of the application.
  5. On the Auth tab, supply a callback URL in the "Redirect URLs" box.
    • If you're creating a desktop application, set this to a locally accessible URL like http://localhost:33333.
    • If you are creating a Web application, set this to a trusted URL where you want users to be redirected to when they authorize your application.
  6. Click Create App. HubSpot then generates the application, along with its associated credentials.
  7. On the Auth tab, note the Client ID and Client secret. You will use these later to configure the driver.

  8. Under Scopes, select any scopes you need for your application's intended functionality.

    A minimum of the following scopes is required to access tables:

    • hubdb
    • oauth
    • crm.objects.owners.read
  9. Click Save changes.
  10. Install the application into a production portal with access to the features that are required by the integration.
    • Under "Install URL (OAuth)", click Copy full URL to copy the installation URL for your application.
    • Navigate to the copied link in your browser. Select a standard account in which to install the application.
    • Click Connect app. You can close the resulting tab.

Using a Private App

To connect using a HubSpot private application token, set the AuthScheme property to "PrivateApp."

You can generate a private application token by following the steps below:

  1. In your HubDB account, click the settings icon (the gear) in the main navigation bar.
  2. In the left sidebar menu, navigate to Integrations > Private Apps.
  3. Click Create private app.
  4. On the Basic Info tab, configure the details of your application (name, logo, and description).
  5. On the Scopes tab, select Read or Write for each scope you want your private application to be able to access.
  6. A minimum of hubdb and crm.objects.owners.read is required to access tables.
  7. After you are done configuring your application, click Create app in the top right.
  8. Review the info about your application's access token, click Continue creating, and then Show token.
  9. Click Copy to copy the private application token.

To connect, set PrivateAppToken to the private application token you retrieved.

Below is the syntax for a DSN:

[CData HubDB Source] Driver = CData ODBC Driver for HubDB Description = My Description AuthScheme = OAuth OAuthClientID = MyOAuthClientID OAuthClientSecret = MyOAuthClientSecret CallbackURL = http://localhost:33333

Execute SQL to HubDB

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 HubDB};AuthScheme = OAuth;OAuthClientID = MyOAuthClientID;OAuthClientSecret = MyOAuthClientSecret;CallbackURL = http://localhost:33333;') cursor = cnxn.cursor() cursor.execute("SELECT PartitionKey, Name FROM NorthwindProducts WHERE Id = '1'") rows = cursor.fetchall() for row in rows: print(row.PartitionKey, row.Name)

After connecting to HubDB in PyCharm using the CData ODBC Driver, you will be able to build Python apps with access to HubDB 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].
