SQL: what is a quick way to get query result?

There are three tables

Create Table InputItems ( ItemID int Primary key, Name nvarchar(250))

Insert into InputItems values (1, 'Raw1')
Insert into InputItems values (2, 'Raw2') 
Insert into InputItems values (3, 'Raw3')

select * from InputItems

Create Table TestItems ( ItemNumber int Primary key, ItemName nvarchar(250), ItemID int)
 
Insert into TestItems values (111, 'Test1', 1) 
Insert into TestItems values(112, 'Test2', 2)
Insert into TestItems values (113, 'Test3', 3)
Insert into TestItems values (114, 'Raw1', 1)
Insert into TestItems values (115, 'Raw2', 2)
Insert into TestItems values (116, 'Raw', 3)

select * from TestItems
 
Create Table ResultItems ( ItemNumber int Primary key, Name nvarchar(250))
select * from ResultItems

delete from ResultItems

declare @Temp table (ItemNumber int, ItemID int)

Insert into @Temp
select t.ItemNumber, t.ItemID
from InputItems i inner join TestItems t
on i.ItemID = t.ItemID and i.Name = t.ItemName 


--found those not match one
Insert into ResultItems
Select t.ItemNumber, t.ItemName
from InputItems i inner join TestItems t
on i.ItemID = t.ItemID and i.Name <> t.ItemName
-- delete those items which ItemID already matched
Delete from ResultItems
where ItemNumber in (select it.ItemNumber from TestItems it inner join @Temp t on it.ItemID = t.ItemID)

-- insert those matched ones
Insert into ResultItems
select distinct t.ItemNumber, t.ItemName
from InputItems i inner join TestItems t
on i.ItemID = t.ItemID and i.Name = t.ItemName

select * from ResultItems


from InputItems we want to get ResultItems table which by return all items in items table match with InputItems'ItemID and (Name matched or Name cannot find from Items table)

(114, Raw1) (115, Raw2) (113, Test3) (116, Raw)

The above bold lines are one of solution. We wonder is there simpler one than this one.

Thx!
