What exactly does "used pages" mean? Are you saying you want to see the total number of pages for the song, the number of pages used from each file or something else entirely? I don't think there is going to be a SQLite query that will be able to pull a text field out of the database (the page order) and process it to turn it into a number. You'd have to do something like write a python script to do that level of processing. I'm still not sure how useful in general it is to have the number of pages used from the list of files used by the song. If you have multiple PDFs, and you are using pages 113-116 of the first and pages 180-182 of the second, just listing 4 and 3 (the number of pages used from each file) doesn't really tell you that much, and unless you also happen to be listing the file paths as part of the song title formatting, it's hard to know which files in the song those numbers refer to.
