Either you stick forever or you remove it now :-) Otherwise you will probably lose comments...

I have removed disqus after 4 days. So I lost about 4 days of comments. I was seduced by the fancy commenting but it failed to satisfy on posting code...

I have tried this a few times, and it seems buggy when used with code tags, part of the code disappear. I hope you will fix this :-)

the indent is buggy, but the edit of code is VERY buggy

Re: Relational algebra: division in sql

laurentschneider — Thu, 10 Apr 2008 07:27:24 -0000

unfortunately it is quite underused, and it is not working as I expect it to do :


SQL> select sid
  2  from catalog
  3  group by sid
  4  having
  5    (select cast(collect(parts_t(pid))as parts_tt) from parts)
  6      submultiset
  7*   cast(collect(parts_t(pid)) as parts_tt)
select sid
*
ERROR at line 1:
ORA-00979: not a GROUP BY expression

the ORA-979 makes no sense. I will open a SR and it may be fixed in Oracle 15

well, this does not cover when supplier have more pieces than parts. So maybe this :

create or replace type parts_t as object (pid number);
/
create or replace type parts_tt as table of parts_t;
/
select sid from 
  (select sid,cast(collect(parts_t(pid)) as parts_tt) x from catalog group by sid)
where  
  ((select cast(collect(parts_t(pid))as parts_tt) from parts)) submultiset x;

laurentschneider — Thu, 10 Apr 2008 06:25:05 -0000

what about this :


select sid from catalog 
group by sid
having collect(pid) = (select collect(pid) from parts);

well, it is maybe slower
