Its probably happening whereever there is a query that needs to get the top
x from an offset point....

Not wanting to rub it in or anything...  I've often looked at that
nasty nasty bit of SQL and wondered whether that could be done
better/easier/more efficiently, but given that I don't have to use  MS
SQL and mysql, postgres and orible all have this capability I've not lost
any sleep over it...

So anyway, my guess is that there is something funky going on
with temporary tables on your DB server....

I was just talking to my SQL Server DBA collegue and he's given me these two
alternates.....

Option 1
=======
with myProject(id, ref, recvDate) as
(select p_id, p_ref, p_recvDate from project
)
select x.*, y.* from (select top 20 * from myProject order by id desc) as x
left join (select top 10 * from myProject order by id desc) as y on x.id =
y.id
where y.id is null

Option 2
======
select top 10 * from (select top 100 * from (select p_id, p_ref, p_recvDate
from project) as x order by p_id desc) as x order by p_id asc

Options 2 is apparently the most efficient.

Just a thought...

Stephen
