Now, think about a Trigger that performs a very complex operation silently.

Debugger usually has a graphic interface that allows you to inspect the variables values at run-time to analyze source code and program flow row-by-row and finally to manage breakpoints.Įach developer loves debugging tools because they are very useful when a program fails in a calculation or when it returns an error. The modern and most important Programming Languages have debugging tools integrated into the development tool. Part 2: Triggers must be thought to work on multiple rows.The first and the second part can be found here: This is the third blog post in the series of articles dedicated to the SQL Server Triggers development.
