SQL Server 2014, Part 9 of 9: T-SQL Working with Data

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.
