Connect to Google Data Catalog Data in RazorSQL

The CData JDBC Driver for Google Data Catalog 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 Data Catalog using wizards in RazorSQL.

Create a JDBC Data Source for Google Data Catalog 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.googledatacatalog.GoogleDataCatalogDriver.
   • 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:googledatacatalog: and is followed by a semicolon-separated list of connection properties.

     Google Data Catalog uses the OAuth authentication standard. Authorize access to Google APIs on behalf on individual users or on behalf of users in a domain.

     Before connecting, specify the following to identify the organization and project you would like to connect to:

     • OrganizationId: The ID associated with the Google Cloud Platform organization resource you would like to connect to. Find this by navigating to the cloud console.

       Click the project selection drop-down, and select your organization from the list. Then, click More -> Settings. The organization ID is displayed on this page.

     • ProjectId: The ID associated with the Google Cloud Platform project resource you would like to connect to.

       Find this by navigating to the cloud console dashboard and selecting your project from the Select from drop-down. The project ID will be present in the Project info card.

     When you connect, the OAuth endpoint opens in your default browser. Log in and grant permissions to the application to completes the OAuth process. For more information, refer to the OAuth section in the Help documentation.

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.googledatacatalog.jar

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

     A typical JDBC URL is the following:

     jdbc:googledatacatalog:ProjectId=YourProjectId;InitiateOAuth=GETANDREFRESH

Query Google Data Catalog 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.
