Es scheint (laut dieser Community und weil ich keine Beispiele für gespeicherte Prozeduren finden konnte, die Ergebnismengen aus anderen gespeicherten Prozeduren als Tabellen in neuen Auswahltabellen verwenden), dass mysql dies entweder nicht unterstützt oder dass es lächerlich schwer ist, das zu tun, was ich mache gehofft zu haben.
Anstatt also gespeicherte Prozeduren aufzurufen, habe ich die Abfragen in diese letzte Prozedur kopiert.
