Get an overview of SQL. What is SQL for? What does it look like? What are some fundamental features of SQL syntax? Learn that SQL is capable of complex operations but uses a simple and readable syntax.
- [Narrator] The purpose of this chapter is to give you…a quick introduction to the basic elements of SQL.…This'll allow you to navigate the concepts and exercises…in the rest of the course.…Each of the lessons in this chapter…will introduce you to a specific statement…or concept in SQL.…These lessons are not exhaustive…and will skip over many essential details.…Those details would be covered later in the course.…SQL is designed for a specific task.…To operate and manage a relational database.…
While capable of complex operations,…SQL is a simple language with a simple syntax.…A statement is the unit of execution in SQL.…In this example we have a select Statement…that retrieves rows from the Countries table,…where the Continent column is equal…to the value of a string literal, Europe.…An SQL statement is terminated with a semi-colon.…The semi-colon may not always be required…in all contexts and all implementations…but it's usually a good idea to include it.…
An SQL statement often includes one or more clauses.…
