Since those triggered actions are typically one or more insert, UPDATE, or DELETE statements, the overhead of triggers can be substantial in a mass insert operation.
由于那些被触发的动作通常是一条或多条insert、UPDATE或delete语句,因此,在数据量很大的insert中,触发器的开销会很大。
If there were a trigger, for example, you would see that reflected in one or more additional insert, Update, or Delete entries in the access plan.
例如,如果有一个触发器的话,那么就会在访问计划中的一个或多个insert、Update或Delete条目中反映出来。
