Subtract one day from datetime

Question

Try this

SELECT DATEDIFF(DAY,  DATEADD(day, -1, '2013-03-13 00:00:00.000'), GETDATE())

OR

SELECT DATEDIFF(DAY,  DATEADD(day, -1, @CreatedDate), GETDATE())

I am not certain about what precisely you are trying to do, but I think this SQL function will help you:

SELECT DATEADD(day,-1,'2013-04-01 16:25:00.250')

The above will give you 2013-03-31 16:25:00.250.

It takes you back exactly one day and works on any standard date-time or date format.

Try running this command and see if it gives you what you are looking for:

SELECT DATEADD(day,-1,@CreatedDate)

To simply subtract one day from todays date:

Select DATEADD(day,-1,GETDATE())

(original post used -7 and was incorrect)

Apparently you can subtract the number of days you want from a datetime.

SELECT GETDATE() - 1

2016-12-25 15:24:50.403

This should work.

select DATEADD(day, -1, convert(date, GETDATE()))

SELECT DATEDIFF (
    DAY, 
    DATEDIFF(DAY, @CreatedDate, -1), 
    GETDATE())
