About the Course

In this 2-hour long project-based course, you will learn how to retrieve data from tables in a database using SQL SELECT statement with SQL Aggregate functions. The aggregate functions we will consider in this project are COUNT, SUM, MIN, MAX and AVG. Aggregate functions are used to summarize data from rows of a table into a single value. In addition, you will learn how to set conditions on the output of an aggregate function using the HAVING clause. Finally, you will learn how to tidy up the result set of aggregate functions using the ROUND function. Note: You do not need to be a data administrator or data analyst to be successful in this guided project, just a familiarity with querying databases using SQL SELECT statement suffice for this project. If you are not familiar with SQL and want to learn the basics, start with my previous guided projects titled “Performing Data definition and Manipulation in SQL." and “Querying Databases using SQL SELECT statement”...

Class was good. I couldn't find the answer to one of the quiz questions even after going back to the lesson referring to it.

This is an easy, basic course for SQL aggregate functions. This is definitely for beginners and the instructor makes a few mistakes and uses some unusual contract examples. However, it was a quick, nice refresher and for those looking to practice aggregate functions, it covers the core topics well. I especially liked the provided sql scripts so you can quickly create your test databases and test on your own system using your SQL dialect of preference. This was my first time to use PostgreSQL and I enjoyed it. It has a few things I like better than MySQL. I like the latter and had it installed prior to taking this course. Thus, I won't be uninstalling it or replacing it but PostgreSQL is a great alternative.

Great course. Instructor moved at a good pace. There were several opportunities to work without instructor guidance and learned new skills. The instructor also pointed out a few nice little tips to keep in mind when working with aggregate functions.

It was a good foundation for a learner although I found he was less detailed than the Power BI course and I missed the additional exercises which did enhance my learning experience. But I would highly recommend this course of an SQL beginner.
