Získání uložené procedury mySQL má za následek další uloženou proceduru

Zdá se (podle této komunity a protože jsem nemohl najít žádné příklady uložených procedur používajících sady výsledků z jiných uložených procedur jako tabulky v nových výběrových tabulkách), že mysql to buď nepodporuje, nebo že je směšně těžké dělat to, co doufal, že to udělám.

Takže místo volání uložených procedur jsem zkopíroval dotazy do této závěrečné procedury.
