View Test’s with Attachments – Excel Report

My objective was to find a way to see which Test’s have Attachments (a quick high level check to see that evidence has been attached).
I found some code on this forum (Thank You) that identified Test’s that contained Attachments but did not include all places an Attachment could be added. I have tried to add other fields to the code (below) to ensure I capture all attachments that may be associated to a Test and believe that there are four possible locations;
Test Set, Test, Run or Step

My questions are;
1) Are these the only locations a user can attached evidence when running a Test?
2) Is this the best structure for my code? – I am not an expert at SQL therefore wondered if this could be completed more efficiently – it does run – but takes a minute or two.
3) Could this be completed a better way?

I have restricted this to specific Release Cycles as that is easier for me to report on.
