查询sql耗时（运行时间）

1)SQL查询所耗时间语句 原理:记录当前时间1,执行SQL语句,记录当前时间2,显示时间2与时间1的差. 由于第一次执行的所耗时间为真实时间,之后会保存在缓存中,所以第二次之后的查询所耗时间都会比第一次明显减少,所以此方法只能作为参考. 如果有更好的方式,感谢博友提供给我,相互学习. declare @begin_date datetime declare @end_date datetime select @begin_date = getdate() --SQL语句 select @end

animation-timing-function animation-timing-function 规定动画的速度曲线.速度曲线定义动画从一套 CSS 样式变为另一套所用的时间.在平常的取值中,主要有以下几个: 值 描述 linear 动画从头到尾的速度是相同的. ease 默认.动画以低速开始,然后加快,在结束前变慢. ease-in 动画以低速开始. ease-out 动画以低速结束. ease-in-out 动画以低速开始和结束. cubic-bezier(n,n,n,n) 在 cub
