Your procedure will look something like this.
Create PROCEDURE [dbo].[DummyProc]
@startDate datetime,
@endDate datetime,
AS
BEGIN
SELECT *
FROM [dbo].[rl_master]
where
phy_confirmed >= @startDate AND
phy_confirmed <= @endDate
END
NOTE: use this for reference to create your own procedure. this is only to demonstrate how it can be done.
