Course Overview
This 2-day course is intended for students who have taken the “Microsoft SQL Server Introduction to Querying” * course, or possess equivalent knowledge gained in the workplace or elsewhere. It may also prove beneficial to delegates wanting to refresh their current knowledge of the subject matter.
Microsoft SQL Server - Advanced Querying
Applies to all versions from SQL Server 2012 through to SQL 2022
DURATION
2 days
INTRODUCTION
Take your querying skills to a new level with this advanced course. Gain a deeper insight into your data and understand how SQL Server internally handles the data you query. Learn how to manipulate data in new and meaningful ways for the purposes of data analysis and reporting. Learn useful techniques for querying temporal data, such as working with date intervals and data islands. Consider best practices for writing efficient queries and avoid common pitfalls.
You will find that this is a comprehensive course for this level, with plenty of illustrated examples and augmented with practical hands-on exercises.
PREREQUISITES
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 and Relational Database Design and Querying Fundamentals” * course.
Additionally, delegates should have attended the 2 day “Microsoft SQL Server Introduction to Querying” * course, or possess equivalent knowledge gained in the workplace or elsewhere.
COURSE OBJECTIVES
Upon successful completion of this course, students will be able to:
• Use Functions Native to SQL Server
