[Qexo-general] problem with same queries

[Daniele Menotti]

I have a problem whith the following two queries. I need to execute them with qexo for my thesis but they don't run.
How can I do?
I suppose the problem is about the use of same and exists, isn't it?
Can you help me?

 

Thank you very much!!!
