Let SQL with a Smile introduce you to the Structured Query Language with a laid-back approach…and a lot of bad jokes! Don’t get bogged down with database details you don’t need yet. SQL With a Smile uses a laid-back approach to teach you just the things you need to get started right now, with easy-to-understand explanations of why things work the way they do, how to write a query that will stand up to a code review, and how to translate your data questions into SQL queries. So sit back, pour yourself your favorite drink, and learn how to: --Identify and understand the main parts of a SQL query --Join tables --Filter results --Apply aggregate functions --Make your own top 10 lists --Write subqueries --And even read other people’s queries, no matter how badly written they may be.
