hello all,
first off, some information:
=====
=====
the table:
Table "facts"
Attribute | Type | Modifier
-------------+--------------+----------
keyword | varchar(80) |
description | varchar(255) |
url | varchar(255) |
the sql:
select keyword from facts as f1
where 1 <> (select count(*) from facts as f2 where f1.keyword = f2.keyword)
order by keyword;
my system:
Linux kernel 2.2.x
p166
32M ram
200M+ swap
=====
=====
it took about 65 minutes to complete. i know that it is doing alot of work,
but it there a way that it could be sped up, like something i could configure
or something that i could do to make it faster?
just looking to see if the time it took to take this is to be expected?
postmaster was using from 78-98% of the cpu for the whole time.
in hind site i wish i would have made keyword not null primary key...
*sigh*, learn from mistakes i guess. now have to fix the duplicates and
move all the rows into a new table with keyword as primary key...
thanks for any help,
and developers: thanks for developing a real non-toy database for the masses,
