SQL Query Where Date = Today Minus 7 Days

Question

I have a SQL table of hits to my website called ExternalHits. I track the URL as URLx and the date the page was accessed as Datex. I run this query every week to get the count of total hits from the week before, and every week I have to manually change the "between" dates. Is there some way I can change my query so that the "between" dates are something like TODAY AND TODAY-7? Ijust want to not have to manually change the dates every week.

    SELECT URLX, COUNT(URLx) AS Count
    FROM ExternalHits
    WHERE datex BETWEEN '02/27/2017' AND '03/05/2017'    
    GROUP BY URLx
    ORDER BY Count DESC; 

Answer 1

declare @lastweek datetime
declare @now datetime
set @now = getdate()
set @lastweek = dateadd(day,-7,@now)

SELECT URLX, COUNT(URLx) AS Count
FROM ExternalHits
WHERE datex BETWEEN @lastweek AND @now
GROUP BY URLx
ORDER BY Count DESC;
