mysql>SELECT BENCHMARK(100, fibonacci(10000));
ERROR 1690 (22003): DOUBLE value is out of range in '(f1@1 + f2@3)'


Uups, was ist das. Die MySQL Version 5.5.9 steigt mit einem SQL-Fehler (ERROR 1690) aus. Ist dies ein Bug?


Ganz im Gegenteil die Fehlermeldung ist hier genau richtig. Denn die Fibonacci-Reihe übersteigt den Definitionsbereich von DOUBLE. Das tat es schon in der 5.1.x und früher. Nur jetzt gibt es eben einen Fehler .. was gut ist!
Warum die genutzte Funktion überhaupt mit DOUBLE arbeitet ist mir bei der Fibonacci-Reihe so oder so schleierhaft :/

BTW: Dies hat nichts mit der ursprünglichen Fragestellung des Autors über die Performance von Proceduren zu tun. Dazu will ich mich nicht äußern.
