Re: the thorny issue of blog comment ownership - Digging in a Habari sandpit

Hi Laurent,

What happened when you tried post code? We took a look at some of these issues and weren't able to replicate them.

I'd be happy to continue investigating until we reach a conclusion.

Disqus can export into RSS or XML.

Although I don't know how many comments you get in 48 hours, it might be feasible to (manually) add the Disqus comments back into WordPress.

Unfortunately, there is no automated tool to do this.

> So, I will stick with it, at least for now.
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

Laurent, it works in 10.2.0.2. I did not try it on 10G R1.

SQL> r
1 select sid from
2 (select sid,cast(collect(parts_t(pid)) as parts_tt) x from catalog group by sid)
3 where
4* ((select cast(collect(parts_t(pid))as parts_tt) from parts)) submultiset x

SID
----------
1

SQL> select * from v$version;

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

Laurent, thanks for the great solution. I did not even know something like submultiset was available.

For the ones interested: submultiset does not exist in 9.2, it comes with 10G R1. It is used to find out if a nested table is a subset of another nested table. Documentation about it is here

Thanks again Laurent.

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;

Re: Relational algebra: division in sql

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
