To stop getting results returned to an application as a consequence of a result in firing, never contain possibly Decide on statements that return success or statements that execute variable assignment in a trigger. Un set off contenente istruzioni Pick che restituiscono risultati all'utente click here for info 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 cause.A induce that features possibly Find statements that return effects for the person or statements that carry out variable assignment calls for Specific dealing with; these returned benefits must be composed into just about every application where modifications to your set off table are permitted. Se è necessario eseguire un'assegnazione di variabile in un cause, utilizzare un'istruzione Established NOCOUNT all'inizio del trigger per impedire la restituzione dei set di risultati.If variable assignment must arise in a induce, use a SET NOCOUNT assertion at the start in the induce to avoid the return of any outcome sets. Anche se un'istruzione TRUNCATE Desk è in effetti un'istruzione DELETE, non attiva un cause in quanto tramite l'operazione non vengono registrate singole eliminazioni di righe.Although a TRUNCATE TABLE assertion is in impact a DELETE assertion, it does not activate a trigger since the operation will not log specific row deletions. Solo gli utenti che dispongono delle autorizzazioni for every eseguire un'istruzione TRUNCATE TABLE devono tuttavia fare attenzione a non eludere un set off DELETE in questo modo.However, only These end users with permissions to execute a TRUNCATE Desk assertion have to have be worried about inadvertently circumventing a DELETE bring about in this manner. L'istruzione WRITETEXT non attiva alcun trigger, indipendentemente dal fatto che sia registrata o meno.The WRITETEXT statement, irrespective of whether logged or unlogged, does not activate a result in. Le istruzioni Transact-SQLTransact-SQL seguenti non sono consentite in un bring about DML:The following Transact-SQLTransact-SQL statements will not be allowed inside a DML set off:
Nelle versioni future di SQL Server la possibilità di ottenere risultati dai trigger non sarà più disponibile.The chance to return final results from triggers are going to be eliminated in the long run version of SQL Server. I trigger che restituiscono established di risultati possono provocare comportamenti imprevisti nelle applicazioni che non sono condition progettate per il loro utilizzo.Triggers that return consequence sets might bring about unexpected habits in purposes that are not designed to perform with them. Evitare di restituire established di risultati dai induce in un nuovo progetto di sviluppo e prevedere interventi di modifica nelle applicazioni che attualmente li restituiscono.Stay clear of returning end result sets from triggers in new growth perform, and prepare to modify programs that currently try this.
But this is actually difficult to induce desire to examine the shorter pat on the assigned chapter ? Could you recommend how a scholar can deliver interest during the assigned chapter opening story?
Lets Profiles being designed on statements utilizing direct manipulation of assertion with embedded hints.
