SQL isn't just for queries; this article shows you one way to use its update capabilities.
By Joe Pluta

Familiarity with the navigational debug commands, explained in the previous TechTip, will help a lot during your debugging sessions. Naturally, simply moving through the source isn’t enough. You’ll also need to be familiar with the actual debugging commands. This entails, among other things, adding and removing breakpoints.
