Thanks Michael. This looks good.
This has confused me somewhat though. I would have
thought that there would be a 1-to-1 ratio between
executions-to-rows processed for insert statements.
If I add the executions column in the above statement,
why do I see more rows processed then executions?
That's what I had based my original logic on. Number
of executions of a particular statement divided by the
elapsed_time to get how fast an insert occurs. What
am I missing?
