How to Query Google Spanner Data in MySQL Workbench

You can use the SQL Gateway from the ODBC Driver for Google Spanner to query Google Spanner data through a MySQL interface. Follow the procedure below to start the MySQL remoting service of the SQL Gateway and work with live Google Spanner data in MySQL Workbench.

Connect to Google Spanner Data

If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can use the built-in Microsoft ODBC Data Source Administrator to configure the DSN. This is also the last step of the driver installation. See the "Getting Started" chapter in the help documentation for a guide to using the Microsoft ODBC Data Source Administrator to create and configure a DSN.

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.

Configure the SQL Gateway

See the SQL Gateway Overview to set up connectivity to Google Spanner data as a virtual MySQL database. You will configure a MySQL remoting service that listens for MySQL requests from clients. The service can be configured in the SQL Gateway UI.
