Module 11: Using Table ExpressionsPreviously in this course, you learned about using subqueries as an expression that returned results to an outer calling query. Like subqueries, table expressions are query expressions, but table expressions extend this idea by allowing you to name them and to work with their results as you would work with data in any valid relational table. Microsoft SQL Server 2016 supports four types of table expressions: derived tables, common table expression (CTEs), views, and inline table-valued functions (TVFs). In this module, you will learn to work with these forms of table expressions and learn how to use them to help create a modular approach to writing queries.Lessons

  • Describe batches and how they are handled by SQL Server.
  • Create and manage transactions with transaction control language (TCL) statements.
  • Use SET XACT_ABORT to define SQL Servers handling of transactions outside TRY/CATCH blocks.

 

 

After completing this course, students will be able to:

  • Describe key capabilities and components of SQL Server 2016.
  • Describe T-SQL, sets, and predicate logic.
  • Write a single table SELECT statement.
  • Write a multi-table SELECT statement.
  • Write SELECT statements with filtering and sorting.
  • Describe how SQL Server uses data types.
