SQL/T-SQL basics

In this part of the chapter, you will get an introduction about SQL language, or to be more precise, the Microsoft version T-SQL (Transact-SQL). Before we actually start to write code, we will cover some basics about language SQL and T-SQL syntax. This knowledge is applicable in all the chapters that will come later, especially in Chapter 4, Database in the Sandbox, and Chapter 5,  Sample Databases.
