Programming From Angela Bradley, your About Programming Editor Dear Subscriber, Welcome to this week's edition of your About Programming Newsletter. This week we take a look at SQL server constraints. We also take a closer look at fonts. Finally we take an in depth look at loops. Have a great week! SQL Server Constraints Database constraints provide you with a way to enforce business logic within your database. In this series of articles, we explore the constraints available to you within Microsoft SQL Server. You probably think you know what a font is Technically, what most people think of as "font" is actually a font family.
