Write below user defined function,which will return varchar as:-

create function [dbo].[fn_Getdateonly] (@pinputdate datetime)
returns varchar(10)
begin
    return cast(year(@pinputdate) as varchar(4)) + '/' +
           cast(month(@pinputdate) as varchar(2)) + '/' +
           cast(day(@pinputdate) as varchar(2));

select dbo.fn_Getdateonly('2014-10-20');

select dbo.fn_Getdateonly('10/20/2014');
