Query of Queries is based on manipulating the record set, which you can create using the cfquery tag and other ways.
When you execute a database query, ColdFusion retrieves the data in a record set. In addition to presenting record set data to the user, you can manipulate this record set to improve your application's performance.
Because a record set contains rows (records) and columns (fields), you can think of it as a virtual database table, or as a spreadsheet. For example, the cfpop tag retrieves a record set in which each row is a message and each column is a message component, such as To, From, and Subject.
