One thing you may need to do is dynamically return a set amount of rows based on user input. This could be for a search function, reports, dropdown lists or whatever. Instead of hard coding a set value you would like to pass in a variable that will then determine the number of rows to return. How can this be done with T-SQL?

When databases suddenly stop working, it can be for a number of different reasons. Human error plays a large part, of course, and the DBA needs to know what these various humans are up to. DDL triggers can help alert the DBA to unauthorized tampering with a production system, of course, but DDL triggers can't tell you everything. At some point, you will need to implement your own checks. Randy certainly reached that point!
