    Introduction to SQL

    Here you can access the books table used in the course.


    Note: When using sample integrations such as those that contain course data, you have read-only access. You can run queries, but cannot make any changes such as adding, deleting, or modifying the data (e.g., creating tables, views, etc.).

    Explore Datasets

    Use the books table to explore the data and practice your skills!

    • Select only the title column.
    • Alias the title column as book_title.
    • Select the distinct author names from the author column.
    • Select all records from the table and limit your results to 10.

    SELECT certification, COUNT(title) AS title_count FROM films WHERE certification in ('G', 'PG', 'PG-13') GROUP BY certification HAVING COUNT(title) > 500 ORDER BY title_count DESC LIMIT 3;
