Overview of this book

SQL is a powerful querying language that's used to store, manipulate, and retrieve data, and it is one of the most popular languages used by developers to query and analyze data efficiently. If you're looking for a comprehensive introduction to SQL, Learn SQL Database Programming will help you to get up to speed with using SQL to streamline your work in no time. Starting with an overview of relational database management systems, this book will show you how to set up and use MySQL Workbench and design a database using practical examples. You'll also discover how to query and manipulate data with SQL programming using MySQL Workbench. As you advance, you’ll create a database, query single and multiple tables, and modify data using SQL querying. This SQL book covers advanced SQL techniques, including aggregate functions, flow control statements, error handling, and subqueries, and helps you process your data to present your findings. Finally, you’ll implement best practices for writing SQL and designing indexes and tables. By the end of this SQL programming book, you’ll have gained the confidence to use SQL queries to retrieve and manipulate data.

Restoring a database

In this section, we will walk through how to restore a database to a MySQL Server instance. Restoring is the process of taking a backup (or copy) of a database and turning it back into a database on the same database server with a different database name or on a separate database server with the same database name as the original database. You can also restore over a database on a server in other words, replacing the current database with a backup of the database but be cautious with this because you will lose data if the database has changed since the last backup. When you back up a MySQL database, the backup process creates SQL files of the entire structure and data of the database. When you restore a database backup, MySQL runs these scripts to recreate the database so that you have an exact copy of the database you backed up. Restoring...
