SQL Server 2012, Part 8 of 9: T-SQL Select, Where, and Clauses

Course description

In this course you’ll learn about the SELECT statement and its incredible flexibility when retrieving data from one or more database tables. You can shape the data you retrieve, and filter it using the WHERE clause. SQL Server rarely returns data in the order you want, so you can use the ORDER BY clause to sort it. Next you’ll learn some advanced ways to select data. With the GROUP BY clause, you can summarize the information in one or more tables, aggregating it various ways, if you wish. You’ll also learn how you can join the data together from multiple tables, efficiently including related data in the result sets.

Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.

Prerequisites

This course assumes that you have at least a basic familiarity with the concept of relational databases and a basic understanding of what SQL Server is and the high-level tools in it, as well as how to create and manage objects using Management Studio. You should also have a basic understanding of how SQL Server implements security, including its authentication and authorization schemes, and how to assign permissions on securable objects to principals.
