Hi Jerry,

I appreciate this article not just for the technical elements but for the deductive reasoning that identifies the problem from the noise. This is a very good guide on the why and where and I agree with the other poster - this should be required reading. Jeff's divide and conquer is a familiar and very useful method also. Jeff has and will be a great resource in things SQL.

I've been consulting for 30 years and have walked into any number of problem scenarios, including the one you describe. This is a more common problem than I originally thought. I appreciate your approach and solution, and congratulate you for solving the problem - I know the customer must have been very happy and that's a very good thing :-D.

Thanks for sharing
