XDG - Base Directory Specification

Directories

Base

The intended use-case for BaseDirectories is to query the paths of user-invisible standard directories that have been defined according to the conventions of the operating system the library is running on.

/*
Suppose we need a query searching for all Equipments that are not being used in any ServiceOrder.

It means, given the following query:

select this_.* 
from  equipment this_ 
where this_.status == 'enabled'
      and not exists (select so_.id as y0_ from service_order so_ where (so_.equipment_id=this_.id))
order by this_.serial_number asc;
