Before you report your conclusions about your data, have you checked whether your 'actionable' figures occurred by chance?

This allows you a measure of confidence that your results are 'significant'. Phil Factor explains how to do it.

User-Defined Functions (UDFs) are an essential part of the database developers' armoury. They are extraordinarily versatile, but just because you can even use scalar UDFs in WHERE clauses, computed columns and check constraints doesn't mean that you should.
