是否有一种方法可以定义日期时间列, 并在插入行时自动填充该列, 而不必使用触发器?
值将是插入行的时间点 。
是 使用默认限制 :
mydatecolumn datetime
constraint DF_myDate DEFAULT (getdate())
是,使用 default :
create table test_table (d_col datetime default current_timestamp)
是, 使用 GetDate () 的默认限制
简单 。 当设计SSMS 中的表格时, 请将字段默认值设置为 gettate ()
只要在更新当前_timestamp 时写一个 < 坚固> > date_timetamp 默认的当前_timestamp
创建表格 FACT_LO ([LOAD_DATE] [日期时间] 默认日期()
