Updating /replacing Contents Of The Table

Is it possible to do an update * where in we update all the contents of the table after selecting specific rows of the same table.

for ex:

create table #Result(rowid int identity(1,1),cust_no int,companyname varchar(100),address varchar(200),zip varchar(9));

insert into #Result(cust_no,companyname,address,zip)
where (customertype='r' and customer.comp_id ='11')
group by customer.cust_no, customer.company


select * from #Result where customerstatus='s';

after this i want to update/replace the #Result with whatever results I have from the select statment.

Thanks for your replies.
