Create Table AS SELECT ... FROM

Hallo,

ich möchte aus einem SELECT eine Tabelle per CREATE TABLE erstellen.
Das SELCECT selber ist sehr schnell, wenn ich es einzeln ausführe. Wenn ich aber CREATE TABLE AS .. voran stelle, dann dauert es fast 30 Sekunden.
Womit kann das zusammenhängen, wenn das einzelne SELECT doch nur 0,02 Sekunden benötig?

Danke


Mark
