Update sort Column linked with group - sql

Question

How can i change the position of one row to change the order
Best to explain with example
I have following table with statuses
Id Name StatusOrder StatusGroup
1 Open 1 1
2 Start 2 1
3 Load 3 1
4 Close 4 1
5 Begin 1 2
6 Open 2 2
7 Close 3 2
I would like to Switch from group one only Status order 2 with 3.
The jump can be more than one row, ex. its also possible that within the same group the order from open moves to status order 3
Sow when i do following select
SELECT * FROM Status WHERE (StatusGroup =1)
Result Set:
Id Name StatusOrder StatusGroup
1 Open 1 1
3 Load 2 1
2 Start 3 1
4 Close 4 1
5 Begin 1 2
6 Open 2 2
7 Close 3 2
I already found example with following article but i do not succeed in it to intgrate that only for one group the order changes

If correctly understood, here you go:
QUERY
create table #t
(
Id INT,
Name VARCHAR(20),
StatusOrder INT,
StatusGroup INT
)
insert into #t values
(1 ,'Open', 1 , 1),
(2 ,'Start', 2 , 1),
(3 ,'Load', 3 , 1),
(4 ,'Close', 4 , 1),
(5 ,'Begin', 1 , 2),
(6 ,'Open', 2 , 2),
(7 ,'Close', 3 , 2)
;with cte as (
select *, row_number() over(partition by StatusGroup order by Id) rn
from #t
)
select case when StatusOrder = 2 then 3 when StatusOrder = 3 then 2 else Id end as Id,
case when StatusOrder = 2 then 'Load' when StatusOrder = 3 then 'Start' else Name end as Name,
StatusOrder,
StatusGroup
from cte
where rn = id
union all
select Id, Name, StatusOrder, StatusGroup
from cte
where rn <> id
drop table #t
OUTPUT
Id Name StatusOrder StatusGroup
1 Open 1 1
3 Load 2 1
2 Start 3 1
4 Close 4 1
5 Begin 1 2
6 Open 2 2
7 Close 3 2
UPDATE
So if you have table where you need update records you can do something like:
;with cte as (
select *, row_number() over(partition by StatusGroup order by Id) rn
from #t
)
update t
set t.Id = (case when cte.StatusOrder = 2 then 3
when cte.StatusOrder = 3 then 2 else t.Id end),
t.Name = (case when cte.StatusOrder = 2 then 'Load'
when cte.StatusOrder = 3 then 'Start' else t.Name end)
from cte
join #t t on cte.id = t.id
where cte.rn = cte.id
