I don't like the idea of hiding the child object's reference to the parent object is why I'm asking. Thx.

  - by Bill Paetzke

  I am parameterizing my web app's ad hoc sql. As a result, I expect the query plan cache to reduce in size and have a higher hit ratio. Perhaps even other important metrics will be improved. Could I use perfmon to track this? If so, what counters should I use? If not perfmon, how could I report on the impact of this change?
