SQL Server 2012, Part 9 of 9: T-SQL Working with Data

LearnNow Online
Updated Aug 22, 2018

Course description

When you retrieve data with a SELECT statement, SQL returns a result set. However, any actions you take on that data (besides just looking at it) involve data manipulation queries that use one of the following three T-SQL statements: INSERT, UPDATE, or DELETE. SQL queries that use these statements are sometimes known as action queries. You’ll learn about the basic uses of these statements. When you modify data in SQL Server, it is important to understand how isolation levels and locking can affect performance and concurrency. You’ll learn about these concepts and how they can affect T-SQL code you write, as well as mitigating measures you can take to avoid problems.

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.


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.
