I cause possono essere nidificati fino a un massimo di 32 livelli.Triggers is often nested to the greatest of 32 amounts. Se un induce modifica una tabella che consist of un altro set off, viene attivato il secondo trigger, che può chiamare a sua volta un terzo result in e così through.If a result in improvements a desk on which there is an additional set off, the 2nd induce is activated and may then get in touch with a 3rd trigger, etc. Se un bring about della catena attiva un ciclo infinito, viene superato il livello massimo di nidificazione e il trigger viene annullato.If any bring about in the chain sets off an infinite loop, the nesting stage is exceeded as well as result in is canceled. Quando un cause Transact-SQLTransact-SQL esegue codice gestito facendo riferimento a una schedule, un tipo o una funzione di aggregazione CLR, questo riferimento viene conteggiato arrive un livello for each il calcolo del limite di nidificazione massimo pari a 32 livelli.Any time a Transact-SQLTransact-SQL induce executes managed code by referencing a CLR routine, form, look at here or aggregate, this reference counts as just one level versus the 32-amount nesting Restrict. I metodi richiamati da codice gestito non vengono inclusi nel conteggio for each questo limiteMethods invoked from in managed code tend not to count versus this Restrict Per disabilitare i cause nidificati, impostare l'opzione nested triggers di sp_configure su 0 (off).To disable nested triggers, established the nested triggers alternative of sp_configure to 0 (off).
