getdate() brings date as well as time with it which may be causing comparison to fail. Also GetDate() returns date and time on the server.

You must compare the right side of the >= with a valid left side.

select *
from orders
where orderdate >= getdate() -3

or

select *
from orders
where orderdate >= DAteadd(day, datediff(day, 3, getdate()), 0)

Did you try the two suggestions in my previous post?

Sorry that was a mistake in my post i was missing the where orderdate >= getdate() - 3

and it worked for the pervious day , it bring me back data for last thursday but i know there is data for friday when i hard code the date

select *
from orders
where orderdate >= getdate() -4

"it bring me back data for last thursday"

Was it already Monday in your timezone? Because if it was you should NOT have got data for Thursday!

(But I agree you should have got data for Friday, unless your timezone is already Tuesday

)
