Topic 13 – Aggregate Functions

In this lesson, we'll explore the syntax and structure of T-SQL queries, focusing on incorporating aggregate functions.

Aggregate functions are potent tools in T-SQL that allow you to perform calculations across sets of rows to generate summary information. This lesson will explore various aggregate functions, such as COUNT, SUM, AVG, MIN, and MAX.

You'll learn how to construct T-SQL queries that utilize aggregate functions to derive valuable insights from your data. We'll cover a range of scenarios, from counting the number of rows in a result set to calculating the average value or finding the highest and lowest values within a dataset.

Through clear explanations and hands-on examples, you'll understand how to leverage aggregate functions effectively to perform data analysis and reporting tasks in SQL Server.

By the end of this lesson, you'll be equipped with the knowledge and skills to write T-SQL queries incorporating aggregate functions, enabling you to extract meaningful summary information from your database quickly. Get ready to elevate your T-SQL querying proficiency and unlock new possibilities in data analysis!
