In this tutorial, you'll learn how to use SQL using mySQL. First, you'll learn what SQL is and the different relational database management systems. Second, you'll learn to install mySQL in your computer. Third, you'll learn to import a real database for you to practice.
Then we'll get into writing queries. First we'll write simple SELECT statements, then SELECT with DISTINCT, and eventually aggregate functions such as COUNT or AVG. We'll then move on to filtering using the WHERE statement. Following that we'll learn to GROUP BY, ORDER BY, and even add a LIMIT. Finally, you'll learn to export your query scripts and results table and importing it into Excel or Power BI.
