I'm looking at having the order in which the sql statements are executed in the trace in the Profiler.
Cary provided me an .rc file to do it with mrskew.exe which is really cool but having the option to include this information in the Profiler (like the "Profile by SQL Statement" section) would be a great addition in opinion as it would be easier when helping developers to debug and improve their applications.
Thank you for your post!
We had considered making this a Profiler option—long ago, in fact—but we decided to implement this feature outside of the Profiler.
One thing we had to consider was that implementing the feature within the Profiler would effectively double the amount of Profiler code path we’d be writing and maintaining. The Profiler’s design, from top to bottom, is 100% dedicated to the goal of focusing the user's attention on the relevant contributors to the duration of the experience explained by the input trace file. Everything in the Profiler is oriented toward this goal.
To sort and regroup the output in another order would make the product a lot more complex. The cost would be out of proportion to the benefit we’d be creating. But cost isn’t the only factor. We feel like it would detract from the single overarching design goal of the tool: again, to focus your attention on the relevant contributors to your experience duration.
As you noted, you can accomplish the goal with the command
(as described in chapter 15 of _The Method R Guide to Mastering Oracle Trace Data, 2nd edition_). The mrskew tool is a nice platform for this, where it’s possible to do some pretty unbelievable things without a lot of effort.
The content of that calls.rc file is below. We will include it in the next release of Method R Workbench.
