I think it's possible with CTE.
Recently I wondered whether it would be possible to implement an operation
that might be called "an accumulated group by". It's when you enumerate the

don't know how well this will work, but...
Assuming you have a row number as well, such as
CREATE TABLE x

row_number int,
The question you're gonna get asked of course is "what are you sorting by?"
If it's for example rowid, then this convoluted thing will work, though

create table tbl (bc int, temp int);
