Why Would You Need to Create SQL Reports?

You already know that SQL is the language used to work with relational databases, right? We use SQL queries to retrieve the data we need in various situations. Thanks to SQL, we can, for example, create reports that will later become the basis for making key business decisions.

Based on data collected by your company, you could create a report showing when you have the highest product sales, when is the best time to start a specific marketing campaign, and when to plan promotions. SQL reports can give you a real market advantage; the one who knows more than the competition gets more customers!

Using SQL and data analytics is just smart. Why guess when you can use data to make better strategic decisions and grow your business?

Here's what you need to do to learn SQL Reports for FREE:

• Create a free LearnSQL.com account or log in if you already have one.
• Start the course. You will have free access to its content until the end of April.

What Will You Learn in This Course?

First of all, you’ll learn some effective data analysis techniques. This course largely focuses on the GROUP BY clause and will deepen your knowledge of it; it’s crucial for creating SQL reports. GROUP BY also appears in our SQL Basics course, but here we extend its use considerably. This course is also a great place to practice popular SQL aggregate functions like COUNT() and SUM().

What is GROUP BY useful for? It will help you compute various statistics in SQL: totals, averages, counts, and so on. It is the basis for all business reports prepared in SQL. Use these reports to analyze your results and achieve your business goals.

Equally important is the ability to control your SQL queries. Thanks to the knowledge gained in this course, you will be able to clean up your long queries and make them more readable and understandable to others. Your colleagues will thank you for it.

In this free SQL report course, you’ll learn how to:

• Use popular SQL aggregate functions like COUNT() or SUM() to summarize data.
• Create custom data classifications using the CASE WHEN syntax
• Use classifications to group objects with the GROUP BY clause.
• Calculate average values, maximum averages, and minimum averages.
• Organize long queries.
• Include multiple metrics in one report.
• Calculate ratios and percentages.
• Compare global and granular metrics.
• Compare different business groups in a single report; we teach you three methods to use.
• Use common table expressions (CTEs).
