Need to learn SQL for work, but don't know where to start? Ever tried to learn, but got bored with dry-as-dust textbooks?
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
