Connect to Google Tasks Data from PowerBuilder via ODBC

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

Connect to Google Tasks 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.

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

Google Tasks API Profile Settings

In the Google Cloud Console, enable the Google Tasks API and create OAuth 2.0 credentials to obtain your Client ID and Client Secret.

Create a Profile for the ODBC Driver for Google Tasks

Follow the steps below to use the Database Painter tool to create a database profile based on an ODBC DSN (data source name) for Google Tasks. In the Database Painter, you can use wizards and the UI to work with Google Tasks 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 Google Tasks DSN in the Data Source menu. 👁 The ODBC DSN, required to create the Database Profile. (Salesforce is shown.)
   
4. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using Google Tasks 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 Google Tasks data into a DataWindow. You can add the following code to the open method:

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