SQL 2012 Developer, Part 13 of 13: Working with XML
with Frank Tillinghast
In this course we’ll explore SQL Server’s support for XML and how it’s improved since being introduced in SQL Server 2000. We’ll discuss SQL Server’s native XML data type—how to declare it as a variable or table column, how it differs from other data types, and how to load data into it using SELECT…FOR XML and the OPENROWSET function. Next you’ll learn the importance of indexing XML columns and that SQL Server supports multiple types of XML indexes including primary, secondary, and the new Selective XML index included as part of SQL Server 2012 Service Pack 1. Then we’ll talk about XML Schemas—how they’re used to validate XML documents, SQL Server’s support for Lax Validation, how to register XML schemas and associate them with XML columns for validation. You’ll learn how to use the XML data type’s native XQuery methods as well as an introduction to FLWOR (flower) expressions. Finally, we’ll wrap up with some best practices and points to consider when you’re deciding if storing data as XML is an appropriate solution for your database application.Course Outline
