convert one to many relation to one to one without using subquery .

Gurus,

I am wondering if there can be a more efficient way of converting the "one to many relation output" to "One to one"
Without using subquery.

TableStructures

create table orders (OrderID int, SalesManID int, amount int)
insert into orders select 1, 11,1000
insert into orders select 2, 22,2000
insert into orders select 3, 33,3000
insert into orders select 4, 44,4000
insert into orders select 5, 11,4000
GO

create table orderDetails (OrderDetailID int, OrderId int, ItemName varchar(500), ItemQuantity int)
insert into orderDetails select 100, 1, 'Juice' ,100
insert into orderDetails select 101, 1, 'Carrots' ,200
insert into orderDetails select 102, 2, 'Biscuts' ,150
insert into orderDetails select 103, 3, 'salt' ,150
insert into orderDetails select 104, 4, 'Pepper' ,160
insert into orderDetails select 105, 5, 'Perfume' ,110
insert into orderDetails select 106, 3, 'soap' ,190
insert into orderDetails select 107, 1, 'Paper' ,850

Now we can use the subqueries and have the one row instead of many that a join will typically yield.
An example of a subquery to return the expected output

SELECT O.OrderId, 
 (select SUM(OD.itemquantity) from orderDetails OD where OD.OrderId = o.OrderID 
 AND itemname not like 'juice'
 ) ItemquantitySum
FROM orders O 

Output will be

Question: Is there a way that the same output can be achieved using the join or any other way?

Thanks in advance for your help.

Cheers
