22. Adding Dynamic Data to Your Pages > 22.1. Retrieving Information

Retrieving Information

Since databases can contain lots of information, you need a way to find just the data you need. Even though your company keeps information about its products, customers, suppliers, and so on in one database, you may only be interested in, say, an alphabetical list of all your customers. After securing that list, you might want to look at a particular customer’s contact information, or perhaps the list of products that person bought.

Understanding Recordsets

To retrieve specific information from a database, you start by creating what’s called a recordset. A recordset—also called a database query—is a command issued to a database asking for particular information: “Hey Database, show me all the customers listed in the Customers table.” It’s the heart of many database operations you’ll perform in Dreamweaver (and a piece of jargon you can’t escape in the dynamic-Web-page business).
