How to Use this Book

 

Throughout this book, we’ll be building a database called companyHR that has two tables - employees and mentorships.

 

The database will be used to demonstrate most of the concepts covered. Hence, you are strongly encouraged to follow along and try out the various examples.

 

To do that, first create a folder on your desktop and name it MySQLExamples.

 

Next, launch MySQL Workbench and create a new file by clicking on File > New Query Tab and save this file as practice.sql (File > Save Script As... ) in the MySQLExamples folder.

 

*** Examples that you should try will be presented in bold. Whenever you see code presented in bold, you should type them into practice.sql and execute them yourself to try them out (even when not prompted to do so). ***

 

The source file for all code presented in bold can be downloaded from https://www.learncodingfast.com/sql.

 

Code that is not in bold is purely for demonstration...
