Connect to Google Calendar Data from PowerBuilder via ODBC

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

Connect to Google Calendar 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.

You can connect to Google APIs on behalf of individual users or on behalf of a domain. Google uses the OAuth authentication standard. See the "Getting Started" section of the help documentation for a guide.

Create a Profile for the ODBC Driver for Google Calendar

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 Calendar. In the Database Painter, you can use wizards and the UI to work with Google Calendar 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 Calendar 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 Calendar 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 Calendar data into a DataWindow. You can add the following code to the open method:

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