Microsoft SQL Server Introduction to Querying

Microsoft SQL Server Introduction to Querying


This course is intended for those who are completely new to querying with Microsoft SQL Server products and need a gentle but concise introduction to the subject.

This would be an ideal course for anyone wishing to learn SQL with the aim of implementing the language in a reporting environment.

This course applies to SQL Server versions from 2008 to 2017. Please inform us which version you require when booking.


Students should ideally be familiar with basic programming concepts and understand the fundamental design of relational databases and the concept of data normalization.


2 days. Hands on.

Course Objectives

This is a comprehensive course, with plenty of illustrated examples, augmented with practical hands on exercises.

The Appendix module(s) detailed in the outline are included in the course material but are not delivered as part of the training due to time constraints. However, as this course is fully modularised, an Appendix module could be swapped out with any one, or more, of the main modules of comparable size and duration if so desired. It is worth noting that this course could also be delivered in its entirety on previous versions of SQL Server.

Upon successful completion of this course, students will be able to:

  • Use SQL Server Management Studio for Querying Purposes
  • Understand the Basic Structure of SQL Server Databases
  • Retrieve Data from Tables Using the SELECT Statement
  • Filter Data Using the WHERE Clause
  • Sort Data Using the ORDER BY Clause
  • Query Data from Multiple Tables by Using Joins
  • Summarize and Group Data Using Aggregate Functions
  • Combine and Limit Result Sets
  • Work with Simple Nested Subqueries
  • Work with Correlated Subqueries
  • Add Records to a Table Using the INSERT Statement
