So take
for example this foreign application variable:
ids = "3,2,5,1,4"
The application then executes this sql:
select * from table where id in (3,2,5,1,4)
As-is, of course, the above query will return the 5 records in a
semi-random (i.e. unpredictable/unreliable) order. And I don't want to
just "order by id" - I want to "order by id(3,2,5,1,4)" (if you see
what I mean)
select *
from table
where id in (3, 2, 5, 1, 4)
order by
case when (id = 3) then 1
when (id = 2) then 2
when (id = 5) then 3
when (id = 1) then 4
when (id = 4) then 5
else null
end
