Omlouvám se za pozdní odpověď, ale tohle je perfektní věc, kterou chcete otestovat, než s tím něco uděláte. Chtěl jsem pro to vytvořit soubor zobrazení, ale zdá se, že je to komplikované a zabere to více času, což se mi momentálně zdá
UPRAVENO
Toto řešení vás může vyburcovat, protože jsem ho testoval. Jak kdy, zkusil jsem tyto dva dotazy zkombinovat a uspěl jsem. Dotaz může vypadat jako něco složitého, ale přináší dokonalé výsledky. Tady je

Ačkoli tento dotaz funguje dobře, ale zde je upravená a optimalizovaná verze tohoto dotazu, opravdu jsem se z tohoto dotazu naučil věci, měli byste se na to také podívat
Podivné chování skupiny v dotazu, které je třeba optimalizovat
