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。 - 2
In a similar manner, you can break up mass UPDATE, DELETE or INSERT operations into separate jobs. 按照类似的方式,您可以将mass UPDATE、DELETE或INSERT操作拆成多个不同的任务。 - 3
Once found, a process that could take up to six months, researchers will insert the genes into bacteria that are genetically engineered to mass-produce enzymes for even finer testing. 一旦一种新的菌类基因被发现,则需要一个大约6个月的程序,研究者们会把基因植入培养菌,那是从基因工程方面大量生产酶,以便于更加深入的实验。
