I bring about possono essere nidificati fino a un massimo di 32 livelli.Triggers could be nested into a optimum of 32 amounts. Se un trigger modifica una tabella che involve un altro cause, viene attivato il secondo induce, che può chiamare a sua volta un terzo set off e così by using.If a cause changes a desk on which there is another induce, the 2nd bring about is activated and might then contact a 3rd result in, etc. Se un bring about della catena attiva un ciclo infinito, viene superato il livello massimo di nidificazione e il result in viene annullato.If any induce while in the chain sets off an infinite loop, the nesting degree is exceeded along with the set off is canceled. Quando un trigger Transact-SQLTransact-SQL esegue codice gestito facendo riferimento a una routine, un tipo o una funzione di aggregazione CLR, questo riferimento viene conteggiato appear un livello per il calcolo del limite di nidificazione massimo pari a 32 livelli.When a Transact-SQLTransact-SQL result in executes managed code by referencing a CLR regimen, type, or combination, this reference counts as one particular level from the 32-amount nesting limit.
