A Generic Histogram Generator for SQL Server
Histograms help people analyze large amounts of data, whether you display them as tables or as charts. This article shows you how to do both.
Dynamically controlling the number of rows affected by a SQL Server query
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!
