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”
In a video that plays in a split-screen with your work area, your instructor will walk you through these steps:
Retrieve data from the employees database
Retrieve data from the employees database using the COUNT function
Select distinct data from fields of a table and use the GROUP BY statement
Use the HAVING clause to set conditions on aggregate functions
Retrieve data from the employees database using the SUM function
Retrieve data from the employees database using the MIN & MAX functions
Retrieve data from the employees database using the AVG function
Use ROUND to tidy up the result set of aggregate functions

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.
