Template Queries
A safer and more widely used technique for retrieving data over HTTP is to use server-side XML templates that encapsulate Transact-SQL queries. Because these templates are stored on the Web server and are referenced via a virtual name, the end user never sees their source code.

As with plain URL queries, results from template queries are returned as either XML or HTML.
