Sorry Jane I wasn't trying to slate the entire article per se, (honest!) - just the title and conclusion.  It clearly has some useful points regarding the easy reporting of identity columns etc. and the general theme of averting disaster before it happens is laudible.

It's just that I have heard too many conversations amongst us techies where technical nuances (use of identity) detract from the real underlying issue (wrong datatype).  I wish people would always attempt to understand the root causes of the many problems that plague us in our day to day jobs and not just try to firefight the symptoms.

Cure The Problem Not The Symptoms...er...Amen
