SQL Server 2016 Introduction To Querying Duration: 2 Days

Course Overview

Introduction A brief overview of the course This 2 day course is intended for students who are new to querying data stored in a Microsoft SQL Server 2016 database, and need a measured and relatively gentle introduction to the subject. It could also prove beneficial to delegates wanting to refresh their existing querying skills. You will find that this is a comprehensive course for this level, with plenty of illustrated examples and augmented with practical hands-on exercises. This course is also intended as a prerequisite to the 2 day "Microsoft SQL Server 2016 Advanced Querying" course.




What you should know before attending this course

Students should ideally be familiar with basic programming concepts.

They should also understand the fundamental design of relational databases including, but not restricted to, the purpose of primary and foreign keys, entity relationships, and data normalization. These prerequisites can be met by taking the 2 day "Microsoft SQL Server 2016 Relational Database Design and Querying Fundamentals" course.

What the course sets out to achieve

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
  • Understand the Components of Transact-SQL (T-SQL)
  • 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 Rows of Data to a Table Using the INSERT Statement
  • Remove Rows from a Table Using the DELETE Statement
  • Modify Existing Rows Using the UPDATE Statement
