How to query for today's date and 7 days before data?

Question

I'm using sql server 2008. How to query out a data which is the date is today and 7 days before today ?

Answer 1

Try this way:

select * from tab
where DateCol between DateAdd(DD,-7,GETDATE() ) and GETDATE() 

Answer 2

Query in Parado's answer is correct, if you want to use MySql too instead GETDATE() you must use (because you've tagged this question with Sql server and Mysql):

select * from tab
where DateCol between adddate(now(),-7) and now()
