Connect to Google Spanner Data from PowerBuilder


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

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

Connect to Google Spanner 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.

Google Spanner uses the OAuth authentication standard. To authenticate using OAuth, you can use the embedded credentials or register an app with Google.

See the Getting Started guide in the CData driver documentation for more information.
