Whatever a database is being used for—websites, bookkeeping, sales and inventory, or even the lowly to-do list—it’s still all about the data. Completely updated for 2014, SQL Essential Training is designed to help users understand the most common language for database wrangling, SQL. Beginning with a quick start introduction for those who want to start working with data immediately, instructor Bill Weinman teaches all the major features of SQL: creating tables; defining relationships; manipulating strings, numbers, and dates; using triggers to automate actions; and working with subselects and views. He offers a solid working knowledge of the language, and shows how to retrieve and manage data efficiently. The final chapter includes a real-world example of building a simple CRUD (Create, Read, Update, and Delete) application using SQL.
