List property elements

What I’m trying to do

Hello everyone, I am trying to evaluate the data that I have written in the properties.
I have two examples for this:

  1. for the school I have a property called “subjects”, here I would like to create a list with all subjects that are listed for the one subject.
    | File | Topics |

  2. i would like to evaluate my lunch, which i write down every day in the property “Lunch”, e.g. via the plugin Tracker.

Things I have tried

I am not a programmer/coder, so my skills are very limited.
I have already tried to find the right instructions via youtube tutorials and the github pages of Dataview and Database, but nothing worked.
An example would be the following:

table Lunch as "Lunch"
from "diary/daily"
where Lunch!= ""
sort file.name desc
