I'm trying to compare two SQL files (a baseline and a proposed basically).

I can add both files into DView, but I'm surprised to see there's no way to differentiate which SQL file are the variables coming from. Here's an extract of what I see with my two SQL files:

How can I tell which SQL file corresponds to the first or second occurrence of Site Run Period Daily (J)?

Note: I am using DView on Ubuntu, is the display the same on Windows?
