Specifica il contesto di sicurezza nel quale viene eseguito il induce.Specifies the security context beneath which the cause is executed.

To stop owning effects returned to an application as a consequence of a cause firing, don't incorporate either Find statements that return outcomes or statements that carry out variable assignment within a trigger. Un cause contenente istruzioni Pick che restituiscono risultati all'utente o istruzioni che eseguono assegnazioni di variabili richiede una gestione particolare. I risultati restituiti devono essere gestiti in ogni applicazione in cui sono consentite modifiche alla tabella di bring about.A induce that includes possibly Choose statements that return final results into the user or statements that execute variable assignment involves special managing; these returned success must be prepared into each individual software through which modifications into the bring about desk are allowed. Se è necessario eseguire un'assegnazione di variabile in un set off, utilizzare un'istruzione SET NOCOUNT all'inizio del set off for each impedire la restituzione dei set di risultati.If variable assignment will have to come about inside a result in, make use of a Established NOCOUNT statement at the start from the bring about to prevent the return of any final result sets. Anche se un'istruzione TRUNCATE TABLE è in effetti un'istruzione DELETE, non attiva un cause in quanto tramite l'operazione non vengono registrate singole eliminazioni di righe.Even though a TRUNCATE TABLE statement is in outcome a DELETE assertion, it doesn't activate a induce as the operation does not log person row deletions. Solo gli utenti che dispongono delle autorizzazioni for each eseguire un'istruzione TRUNCATE Desk devono tuttavia fare attenzione a non eludere un cause DELETE in questo modo.Having said that, only These consumers with permissions to execute a TRUNCATE Desk statement want be worried about inadvertently circumventing a DELETE set off this fashion. L'istruzione WRITETEXT non attiva alcun result in, indipendentemente dal fatto che sia registrata o meno.The WRITETEXT assertion, no matter if logged or unlogged, would not activate a cause. Le istruzioni Transact-SQLTransact-SQL seguenti non sono consentite in un result in DML:The next Transact-SQLTransact-SQL statements are not permitted within a DML bring about:

Take note, if you believe you'll want to use a special template or topic for your store, look at setting up it ahead of doing any additional customizations (see Stage seven).

I trigger possono essere nidificati fino a un massimo di 32 livelli.Triggers may be nested to a greatest of 32 concentrations. Se un result in modifica una tabella che include things like un altro trigger, viene attivato il secondo result in, che può chiamare a sua volta un terzo cause e così by way of.If a set off improvements a table on which there is an additional cause, the 2nd set off is activated and may then call a 3rd set off, etc. Se un result in della catena attiva un ciclo infinito, viene superato il livello massimo di nidificazione e il bring about viene annullato.If any bring about while in the chain sets off an infinite loop, the nesting level is exceeded and the set off is canceled. Quando un set off Transact-SQLTransact-SQL esegue codice gestito facendo riferimento a una schedule, 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.Whenever a Transact-SQLTransact-SQL induce executes managed code by referencing a CLR regime, sort, or mixture, this reference counts as 1 level in opposition to the 32-degree nesting Restrict. I metodi richiamati da codice gestito non vengono inclusi nel conteggio for every questo limiteMethods invoked from inside managed code never count towards this Restrict Per disabilitare i induce nidificati, impostare l'opzione nested triggers di sp_configure su 0 (off).To disable nested triggers, established the nested triggers selection of sp_configure to 0 (off).

So DBMS utilize the framework for the higher enforcement of data safety and privateness, Better information integration: info is residing in the different resources to promotes an integrated look at that provide you with a distinct picture of the structured information that is become much easier to obtain, Minimized information inconsistency: information inconsistency take place in the event the anyone possessing two entries with different name like Dennis Ritchie or Dr. Ritchie so DBMS cut down this by using appropriate created database, improved decision building:

Ricorsione direttaDirect recursion Quando viene utilizzata la ricorsione diretta, un'applicazione aggiorna la tabella T1,With direct recursion, the appliance updates table T1. il che attiva il result in TR1 che aggiorna la tabella T1.This fires result in TR1, updating table T1. Poiché la tabella T1 è stata aggiornata, viene di nuovo attivato il cause TR1 e il processo viene quindi ripetuto.Since table T1 was current, set off TR1 fires once again, etc. Nell'esempio seguente vengono utilizzati entrambi i tipi di ricorsione indiretta e diretta. Si supponga che for every la tabella T1 vengano definiti due set off di aggiornamento, TR1 e TR2.The following illustration employs equally oblique and immediate induce recursion Assume that two update triggers, TR1 and TR2, are outlined on desk T1.
