Quick, learn-by-example lessons start with simple data retrieval and sorting, move on to filtering and grouping, and then build to more-advanced topics, including joins, subqueries, views, and transactions. Whether you're an analyst, developer, data scientist, or Microsoft Office user, you'll find straightforward, practical answers. You can download the sample database to follow along with the examples.
