How to connect to Google Translate Data from IntelliJ

The CData JDBC Driver for Google Translate enables you to access Google Translate 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 Translate data in IntelliJ.

Create a JBDC Data Source for Google Translate

Follow the steps below to add the driver JAR and define connection properties required to connect to Google Translate 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.api.jar, located in the installation directory.
   • JDBC Driver Class: In this menu, select cdata.jdbc.api.APIDriver from the list.

   • Database URL: Enter the connection URL in the JDBC URL property. The URL must start with jdbc:api: and includes connection properties separated with semicolons.

     Authentication

     Google Cloud Translation API requires OAuth 2.0 authentication to ensure secure access to translation services, datasets, glossaries, and adaptive MT resources. This authentication method allows you to securely connect to your Google Cloud project and manage translation resources with proper authorization.

     OAuth 2.0 Setup and Configuration

     Step 1: Create Google Cloud Project and Enable API

     To set up OAuth authentication:

     1. Visit the Google Cloud Console
     2. Create a new project or select an existing project
     3. Note down your Project ID (required for all API calls)
     4. Navigate to "APIs & Services" > "Library"
     5. Search for and enable the "Cloud Translation API"
     6. Go to "APIs & Services" > "Credentials"
     7. Click "Create Credentials" and select "OAuth Client ID"
     8. Configure the OAuth consent screen if prompted
     9. Select "Desktop application" or "Web application" as appropriate
     10. Set the authorized redirect URI (CallbackURL)
     11. Copy the Client ID and Client Secret for use in your connection

     Required Connection Properties

     • AuthScheme: Set this to OAuth (required)
     • OAuthClientId: Client ID from Google Cloud Console (required)
     • OAuthClientSecret: Client secret from Google Cloud Console (required)
     • CallbackURL: Redirect URI specified in your OAuth application (required)
     • InitiateOAuth: Set to GETANDREFRESH for automatic token management (recommended)
     • ProjectId: Your Google Cloud project ID or project number (required for queries)

     Required OAuth Scopes

     The Google Cloud Translation API Profile requires the following OAuth scope:

     • https://www.googleapis.com/auth/cloud-translation - Full access to Cloud Translation API resources including translation, datasets, glossaries, and adaptive MT

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.api.jar
     

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

     

     A typical JDBC URL is the following:

     jdbc:api:Profile=C:\profiles\GoogleTranslate.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;

Edit and Save Google Translate 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.
