I've a function that does something like:
create temp sequence tmp_seq;
for _row in (select id from mylist where Weight<_Weight)
loop
alter sequence tmp_seq restart with 1;
-- perform setval('tmp_seq',1,false);
insert into mytop (id,n) select id, nextval('tmp_seq')
from biglist join mylist on biglist.id=mylist
order by biglist.something limit 3;
end loop;
drop sequence tmp_seq;
I'd expect something like
1,1
1,2
1,3
127,1
127,2
127,3
but I get something like
1,5
1,6
1,7
127,55
127,56
127,57
152,6
152,7
152,8
what should I do to obtain the result I was expecting?
