Erhalten der Anzahl einer Unteranfrage

Question

Ich muss das Ergebnis einer SQL-Abfrage zählen, die ich nicht kontrollieren kann. Meine Idee ist es, das innere SQL mit einer Wrapper-Count-Abfrage zu umhüllen. Die äußere SQL ist ziemlich einfach, hier ist was ich bekam:

select count(*) from (x) as CountQuery 

wo x ist was auch immer die innere SQL geht. Das Problem dabei ist, dass einige Abfragen abstürzen würden, nämlich IF ELSE END.

Wie erstelle ich ein Wrapper-SQL, das erfolgreich SQL umschließt? Hier

ist ein Beispiel für eine der inneren SQL I zählen müssen:

Sie können eine temporäre Tabelle auf der Abfrage erstellen basiert und dann die Zeilen darin zählen.

CREATE TEMPORARY TABLE my_results 
<whatever query you have>; 

SELECT COUNT(*) FROM my_results;
