Connect to Google Spanner Data in IntelliJ

Integrate connectivity to Google Spanner data with wizards in IntelliJ.

The CData JDBC Driver for Google Spanner enables you to access Google Spanner as a JDBC data source, providing integration with rapid development tools in IDEs. This article shows how to use the data source configuration wizard to connect to Google Spanner data in IntelliJ.

Create a JBDC Data Source for Google Spanner

Follow the steps below to add the driver JAR and define connection properties required to connect to Google Spanner data.

  1. In the Data Sources window, right-click and then click Add Data Source -> DB Data Source.
  2. In the Data Source Properties dialog that appears, the following properties are required:

    • JDBC Driver Files: Click the button next to this menu to add the JDBC Driver file cdata.jdbc.googlespanner.jar, located in the installation directory.
    • JDBC Driver Class: In this menu, select cdata.jdbc.googlespanner.GoogleSpannerDriver from the list.
    • Database URL: Enter the connection URL in the JDBC URL property. The URL must start with jdbc:googlespanner: and includes connection properties separated with semicolons.

      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.

      Built-in Connection String Designer

      For assistance in constructing the JDBC URL, use the connection string designer built into the Google Spanner JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.googlespanner.jar

      Fill in the connection properties and copy the connection string to the clipboard.

      A typical JDBC URL is the following:

      jdbc:googlespanner:ProjectId='project1';InstanceId='instance1';Database='db1';InitiateOAuth=GETANDREFRESH

Edit and Save Google Spanner Data

To discover schema information, right-click the data source you just created and click Refresh Tables. To query a table, right-click it and then click Open Tables Editor. You can also modify records in the Table Editor.
