Welcome to our "How to INSERT, UPDATE, and DELETE Data in SQL" course, where you will learn how to manage data in SQL!

Data in any database is constantly changing. You will learn how to add new information to a database, modify database information, and remove information from a database.

We assume that you already know how to create SQL queries and how to work with them. If you don't, feel free to take a look at our SQL Basics course first.

We'll provide you with easy-to-understand examples based on a simple table named user:

user (id, name, age)

Each user has a unique id, a specific name, and an age. Easy, right?

To make things more exciting, though, you'll be working with another table, dish. Let's take a look at it.


Select all data from the dish table, and explore the contents.

When you're done, click Run and check code to continue.
