How to connect to Google Translate Data with Squirrel SQL client

The CData JDBC Driver for Google Translate enables you to execute queries to Google Translate data in tools like Squirrel SQL Client. In this article, you will create a JDBC data source for Google Translate data and execute queries.

Add the JDBC Driver for Google Translate

Follow the steps below to add the driver JAR.

1. In Squirrel SQL, click Windows -> View Drivers.
2. Click the plus icon to open the Add Driver wizard.
3. In the Name box, enter a user-friendly name for the driver; for example, CData JDBC Driver for Google Translate.
4. In the Example URL box, enter jdbc:api:
5. In the Extra Class Path tab, click Add.
6. In the file explorer dialog that opens, select the JAR file for the driver, located in the lib subfolder of the installation directory.
7. Click List Drivers to populate the Class Name menu with the class name for the driver, cdata.jdbc.api.APIDriver.

Define Connection Properties

Follow the steps below to save connection properties in the driver alias.

1. Click Windows -> View Aliases.
2. In the pane that lists the aliases, click the plus icon.

3. In the Add Alias wizard that opens, the following fields are required for the JDBC driver:

   • Name: Enter a name for the alias; for example, CData Google Translate Source.
   • Driver: Select the CData JDBC Driver for Google Translate.
   • URL: Enter jdbc:api:
   
4. If you want to define any additional properties, click Properties.
5. In the Driver properties tab of the dialog that appears, select the Use driver properties checkbox.
6. In the Specify column, select the checkboxes for the required connection properties.

   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

   Below is a typical connection string:

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

   
7. In the dialog that appears after you click OK, click connect to test the connection.

Discover Schemas and Query Google Translate Data

After the metadata has loaded, a new tab for the Google Translate data source is displayed. On the Objects subtab, you can discover schema information, such as the available tables and views.

To view table data, select the table on the Objects tab. The table data is then loaded in a grid on the Content tab.

To execute an SQL query, enter the query on the SQL tab and then click Run SQL (the runner icon). For example:

SELECT LanguageCode, DisplayName FROM SupportedLanguages WHERE ProjectId = 'my-project-12345'
