OVERVIEW

This course is the foundation for learning T-SQL. It follows the Microsoft certificate 70-461 “Querying Microsoft SQL Server” and 70-761 “Querying data with Transact-SQL”. Although these exams are no longer available, this curriculum allows you to master T-SQL.

You will be able to install for free the software used on this course – SQL Server and SQL Server Management Studio (SSMS).

There are regular quizzes to support your learning.

Once finished, you will be able to: manipulate numbers, strings and dates; create databases and tables; insert data and create analyses; and appreciate how they can all be used in T-SQL.

WHO IS THE COURSE FOR?

This course is for anybody new to SQL Server, or with limited experience, who wants to learn T-SQL. No prior knowledge is required.

It is also suitable as an SQL refresher course.
