Using the CData ODBC Driver for Coinbase in PyCharm


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

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 Coinbase 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 Coinbase 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 Coinbase

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 Coinbase Profile on disk (e.g. C:\profiles\Coinbase.apip). Next, set the ProfileSettings connection property to the connection string for Coinbase (see below).

Coinbase API Profile Settings

Coinbase uses OAuth-based authentication.

First you need to register an OAuth app with Coinbase. This is done from your account under 'Settings' > 'API Access' > 'New OAuth2 Application'.

After setting the following connection properties, you are ready to connect:

  • AuthScheme: Set this to OAuth.
  • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
  • OAuthClientId: Set this to the ClientID that is specified in you app settings.
  • OAuthClientSecret: Set this to the ClientSecret that is specified in you app settings.
  • CallbackURL: Set this to the Redirect URI you specified in your app settings.

Below is the syntax for a DSN:

[CData API Source] Driver = CData ODBC Driver for Coinbase Description = My Description Profile = C:\profiles\Coinbase.apip Authscheme = OAuth OAuthClientId = your_client_id OAuthClientSecret = your_client_secret CallbackUrl = your_callback_url

Execute SQL to Coinbase

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\Coinbase.apip;Authscheme = OAuth;OAuthClientId = your_client_id;OAuthClientSecret = your_client_secret;CallbackUrl = your_callback_url;') cursor = cnxn.cursor() cursor.execute("SELECT Id, Amount FROM Deposits WHERE Committed = 'true'") rows = cursor.fetchall() for row in rows: print(row.Id, row.Amount)

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