  • Course Notes

    Use this workspace to take notes, store sample queries, and build your own interactive cheat sheet!

    You will need to connect your SQL cells to an integration to run a query.

    • You can use a sample integration from the dropdown menu. This includes the Course Databases integration, which contains tables you used in our SQL courses.
    • You can connect your own integration by following the instructions provided here.

    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.).

    Take Notes

    Add notes here about the concepts you've learned and SQL cells with code you want to keep.
