Se un set off della catena attiva un ciclo infinito, viene superato il livello massimo di nidificazione e il bring about viene annullato.If any set off from the chain sets off an infinite loop, the nesting stage is get more exceeded along with the bring about is canceled.

I metodi richiamati da codice gestito non vengono inclusi nel conteggio per questo limiteMethods invoked from inside managed code do not count towards this Restrict For every disabilitare i set off nidificati, impostare l'opzione nested triggers di sp_configure su 0 (off).To disable nested triggers, set the nested triggers possibility of sp_configure to 0 (off).
