This MySQL course provides new PHP developers with the prerequisite knowledge necessary to learn to build database-driven websites with PHP and MySQL. It does not cover PHP, but it prepares you for learning PHP to integrate with MySQL. Although most of the SQL learned in the course is applicable to all major databases, including SQL Server, Oracle, and PostgreSQL, it focuses on MySQL.
This course starts with the basics of relational databases. You will learn to use simple SELECT queries to pull data, and then move on to more advanced SELECTs and data manipulation. You will shape the results of your queries to create relevant reports. Once you have mastered the basics, you will get hands-on with complex data retrieval methods like subqueries, joins, outer joins, and unions. Finally, you will use INSERT, UPDATE, and DELETE while learning best practices for maintaining your records.
By the end of this MySQL for PHP course, you will know MySQL and SQL well enough to start using it with PHP (and elsewhere).
