Start here if you're new to SQL Server. Learn the basics of T-SQL for SQL Server, retrieve data from an SQL Server database and build simple reports.
Databases are part of our everyday life, and being able to communicate with them is essential. This course will teach you the basics of T-SQL, a powerful query language that lets you work with many types of data.
The SQL Basics in MS SQL Server course starts with simple queries performed on a single table. These exercises will show you how to retrieve exactly what you need. Next, you'll start working with multiple tables. You will find out about the subtle differences between various joining methods, including INNER JOIN, LEFT JOIN, RIGHT JOIN, and OUTER JOIN.
As you go deeper into the course, you'll master using the GROUP BY function to create simple reports. You'll also start investigating subqueries. Finally, you can test your knowledge (and earn your certificate!) in a comprehensive quiz.
Looking to get started in T-SQL? Give this course a try – the fascinating world of T-SQL queries is only a click away!
