Trello ODBC Driver

The Trello ODBC Driver is a powerful tool that allows you to connect with live Trello, directly from any applications that support ODBC connectivity.

Access Trello like you would a database - access Lists, Cards, Boards, etc. through a standard ODBC Driver interface.



This article demonstrates how to use the CData ODBC Driver for Trello to connect to Trello data and execute queries in PowerBuilder.

The CData ODBC Driver for Trello can be used from any platform or development technology that supports ODBC, including PowerBuilder. This article shows how to connect to Trello data and execute queries from the Database Painter and controls such as the DataWindow.

Connect to Trello as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Trello uses token-based authentication to grant third-party applications access to their API. When a user has granted an application access to their data, the application is given a token that can be used to make requests to Trello's API.

Trello's API can be accessed in 2 different ways. The first is using Trello's own Authorization Route, and the second is using OAuth1.0.

  • Authorization Route: At the moment of registration, Trello assigns an API key and Token to the account. See the Help documentation for information on how to connect via the Authorization route.
  • OAuth Route: Similar to using Authorization, OAuth creates an Application Id and Secret when you create your account. See the Help documentation for information on how to to connect.

Create a Profile for the ODBC Driver for Trello

Follow the steps below to use the Database Painter tool to create a database profile based on an ODBC DSN (data source name) for Trello. In the Database Painter, you can use wizards and the UI to work with Trello data.

  1. In PowerBuilder, click Tools -> Database Painter.
  2. In the Objects window in the Database Painter, right-click the ODBC node and click New Profile.
  3. On the Connection tab, enter a name for the profile and select the Trello DSN in the Data Source menu.
  4. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using Trello Data with PowerBuilder Controls

You can use standard PowerBuilder objects to connect to ODBC data sources and execute queries. The following example shows how to retrieve Trello data into a DataWindow. You can add the following code to the open method:

SQLCA.DBMS = "ODBC" SQLCA.DBParm = "ConnectString='DSN=CData Trello Source'" CONNECT USING SQLCA; dw_boards.SetTransObject(SQLCA); dw_boards.Retrieve();
