2. In the new window, configure the connection to Hacker News with a JDBC URL.

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the Hacker News 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.

   Connecting to HackerNews

   The HackerNews API (powered by Firebase) is a public API that requires no authentication. You can connect and query data immediately without any credentials.

   After setting the following connection properties, you are ready to connect:

   • AuthScheme: Set this to None.

   Example connection string:

   Profile=C:\profiles\HackerNews.apip;AuthScheme=None
   

   👁 Using the built-in connection string designer to generate a JDBC URL (Salesforce is shown.)
   
3. Set URL to the connection string, e.g.,

   jdbc:api:Profile=C:\profiles\HackerNews.apip;AuthScheme=None

4. Click "Apply" and "OK" to save the connection string 👁 A configured Data Source (Salesforce is shown).
   

At this point, you will see the data source in the Data Explorer.

Execute SQL Queries Against Hacker News

To browse through the Hacker News entities (available as tables) accessible through the JDBC Driver, expand the Data Source.

To execute queries, right click on any table and select "New" -> "Query Console."

In the Console, write the SQL query you wish to execute. For example:
