abs(DATEDIFF(dd,date_value,getdate()))'No of days before expiry'
from dbo.Test_X
where Application_Name='xyz'

AND abs(DATEDIFF(dd,date_value,getdate()))<@NDAYS

RAISERROR (N'This is message %s %d.', -- Message text.
           10, -- Severity,
           1, -- State,
           N'number', -- First argument.
