SQL Server 2005 Using DateAdd to add a day to a da

问题:

How do I in SQL Server 2005 use the DateAdd function to add a day to a date

回答1:

Use the following function:

DATEADD(type, value, date)

• date is the date you want to manipulate

• value is the integere value you want to add (or subtract if you provide a negative number)

• type is one of:

  • yy, yyyy: year
  • qq, q: quarter
  • mm, m: month
  • dy, y: day of year
  • dd, d: day
  • wk, ww: week
  • dw, w: weekday
  • hh: hour
  • mi, n: minute
  • ss or s: second
  • ms: millisecond
  • mcs: microsecond
  • ns: nanosecond

SELECT DATEADD(dd, 1, GETDATE()) will return a current date + 1 day

DECLARE @MyDate datetime

-- ... set your datetime's initial value ...'

DATEADD(d, 1, @MyDate)

Try following code will Add one day to current date

select DateAdd(day, 1, GetDate())

And in the same way can use Year, Month, Hour, Second etc. instead of day in the same function
