Google Cloud Storage JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with Google Cloud Storage.



Connect to Google Cloud Storage from wizards and query Google Cloud Storage data from the GUI in the RazorSQL database management tool.

The CData JDBC Driver for Google Cloud Storage enables standards-based access from third-party tools, from wizards in IDEs to data management and analysis tools. This article shows how to connect to Google Cloud Storage using wizards in RazorSQL.

Create a JDBC Data Source for Google Cloud Storage Data

  1. Open the RazorSQL application and, in the Connections menu, select Add Connection Profile -> Other -> JDBC.
  2. In the Connection Wizard that appears, set the following properties:
    • Driver Location: Set this property to the path to the lib subfolder in the installation directory.
    • Driver Class: Set the driver class to cdata.jdbc.googlecloudstorage.GoogleCloudStorageDriver.
    • Username: Enter the username. (This property can also be set in the JDBC URL.)
    • Password: Enter the password. (This property can also be set in the JDBC URL.)
    • JDBC URL: Enter connection parameters. The JDBC URL begins with jdbc:googlecloudstorage: and is followed by a semicolon-separated list of connection properties.

      Authenticate with a User Account

      You can connect without setting any connection properties for your user credentials. After setting InitiateOAuth to GETANDREFRESH, you are ready to connect.

      When you connect, the Google Cloud Storage OAuth endpoint opens in your default browser. Log in and grant permissions, then the OAuth process completes

      Authenticate with a Service Account

      Service accounts have silent authentication, without user authentication in the browser. You can also use a service account to delegate enterprise-wide access scopes.

      You need to create an OAuth application in this flow. See the Help documentation for more information. After setting the following connection properties, you are ready to connect:

      • InitiateOAuth: Set this to GETANDREFRESH.
      • OAuthJWTCertType: Set this to "PFXFILE".
      • OAuthJWTCert: Set this to the path to the .p12 file you generated.
      • OAuthJWTCertPassword: Set this to the password of the .p12 file.
      • OAuthJWTCertSubject: Set this to "*" to pick the first certificate in the certificate store.
      • OAuthJWTIssuer: In the service accounts section, click Manage Service Accounts and set this field to the email address displayed in the service account Id field.
      • OAuthJWTSubject: Set this to your enterprise Id if your subject type is set to "enterprise" or your app user Id if your subject type is set to "user".
      • ProjectId: Set this to the Id of the project you want to connect to.

      The OAuth flow for a service account then completes.

      Built-in Connection String Designer

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

      java -jar cdata.jdbc.googlecloudstorage.jar

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

      A typical JDBC URL is the following:

      jdbc:googlecloudstorage:ProjectId='project1';InitiateOAuth=GETANDREFRESH

Query Google Cloud Storage Data and Select Tables

After establishing a connection, the wizard will close and the connection will be available in the connections panel. You can then query the tables.
