Question

I’m trying to basically dynamically set two variables (@month and @year) to be whatever the previous month and year were.

So in today’s case @month = 7 and @year = 2012

But I want something safe for the year roll around, so if it’s 1/1/2013 I would get @month = 12 and @year = 2012.

Thanks!

This is what I have.

declare @month              int
declare @year               int

set @month = month (getDate ())-1
set @year = 2012

You can use DATEADD to subtract a month from the current date, then grab the MONTH and YEAR portions:

DECLARE @monthAgo dateTime
DECLARE @month int
DECLARE @year int

SET @monthAgo = DATEADD(month, -1, GETDATE())
SET @month = MONTH(@monthAgo)
SET @year = YEAR(@monthAgo)
