I need help on t-sql date:

I have this: DATEDIFF(DAY,StartDate, getdate())  =  '14' to find the startdate is 14 days pass.

 then I also need to find those that occur every 7 days thereafter, etc 21 days, 28 days, 35 days

Can someone please help?

WHERE (datediff(day,StartDate,getdate()) % 7 = 0)

Open in new window


This will get any where the result from your datediff function divides evenly by 7

How about something like this.

WHERE
   DATEDIFF(DAY,startDate,getdate()) = 14 OR (DATEDIFF(DAY,startDate,getdate())  > 14 AND DATEDIFF(DAY,startDate,getdate())%7 = 0)
