SQL Server: Get data for only the past year

Question

I am writing a query in which I have to get the data for only the last year. What is the best way to do this?

SELECT ... FROM ... WHERE date > \'8/27/2007         


        

Answer 1

declare @iMonth int
declare @sYear varchar(4)
declare @sMonth varchar(2)
set @iMonth = 0
while @iMonth > -12
begin
    set @sYear = year(DATEADD(month,@iMonth,GETDATE()))
    set @sMonth = right('0'+cast(month(DATEADD(month,@iMonth,GETDATE())) as varchar(2)),2)
    select @sYear + @sMonth
    set @iMonth = @iMonth - 1
end

Answer 2

Well, I think something is missing here. User wants to get data from the last year and not from the last 365 days. There is a huge diference. In my opinion, data from the last year is every data from 2007 (if I am in 2008 now). So the right answer would be:

SELECT ... FROM ... WHERE YEAR(DATE) = YEAR(GETDATE()) - 1

Then if you want to restrict this query, you can add some other filter, but always searching in the last year.

SELECT ... FROM ... WHERE YEAR(DATE) = YEAR(GETDATE()) - 1 AND DATE > '05/05/2007'

Answer 3

Look up dateadd in BOL

dateadd(yy,-1,getdate())

Answer 4

GETDATE() returns current date and time.

If last year starts in midnight of current day last year (like in original example) you should use something like:

DECLARE @start datetime
SET @start = dbo.getdatewithouttime(DATEADD(year, -1, GETDATE())) -- cut time (hours, minutes, ect.) --  getdatewithouttime() function doesn't exist in MS SQL -- you have to write one
SELECT column1, column2, ..., columnN FROM table WHERE date >= @start

Answer 5

The following adds -1 years to the current date:

SELECT ... From ... WHERE date > DATEADD(year,-1,GETDATE())

Answer 6

I, like @D.E. White, came here for similar but different reasons than the original question. The original question asks for the last 365 days. @samjudson's answer provides that. @D.E. White's answer returns results for the prior calendar year.

My query is a bit different in that it works for the prior year up to and including the current date:

SELECT .... FROM .... WHERE year(date) > year(DATEADD(year, -2, GETDATE()))

For example, on Feb 17, 2017 this query returns results from 1/1/2016 to 2/17/2017
