To operate on time in SQL, You need to master four time functions:Dateadd, datediff, datepart, datename.
Dateadd is to add or subtract a time on a specified date.For example, if you add a 3-day select dateadd (day, 3, '2017-05-06 ') on the specified date, the returned result is 2010-05-09.
Datediff is the date and time parameter that returns two specified dates.For example, select dateadd (day, '2017-05
