Chapter 11 covered doing basic select statements (reads) from the MySQL database. This chapter covers the other essential functions encapsulated in the acronym CRUD—Create, Read, Update, and Delete. We’ll cover some more complicated selects as well as creating records, updating records, and deleting records; how to create tables; and more. Often, when installing Drupal (not using Acquia Dev Desktop), you’ll need to create a MYSQL database first. There are other times you’ll need to look in the database to check the data directly to see if there’s some problem. This chapter will round out your basic MYSQL skills so you can field more of the common issues you may face.
