Hi,
I have a problem I dont really know how to solve except for writing a
function.
I have a table with prices;
SecCode| Price | PriceDate
---++---
A0001 | 13.10 | 2004-10-30
A0001 | 13.03 | 2004-10-29
A0001 | 13.12 | 2004-10-28
A0001 | 12.45 | 2004-10-27
Hi,
when creating a query with a subselect
SELECT name, (SELECT max(pop) FROM cities WHERE cities.state = states.name) AS max_pop
FROM states;
then it is not possible to sort after max_pop or use max_pop in a function or a CASE.
am I dont anything wrong or is this meant to be the case?
Thanks
Will there be a release 7.4.7 in the future?
When can the production release of 8 be expected?
thanks

This is a very interesting option. My biggest concern is performance:
the project will require tables with millions of tuples. How does the
performance of such user created types compare to using native types? Or
are they 'built' using the same structure?
Thanks again!

Possibly.

When it's ready. Probably this year.

Hm.
Well, the second question is trivial indeed :-) ,even though I had
pipelining in mind when writting it...
(which is not so query oriented but rather plan/executor oriented)
However, I'm more interested in the first question.
Thank you very much,

Hi,
On Tue,
You can't use the alias name in the sort, case, where etc.. you have
to use the entire subselect.
So you would order by (select max(pop)...)
and you would also case the full thing as well.
A bit of a pain but Tom Lane explained it in a post a couple days ago
and said the system was optimized so it

Here max_pop is naming the whole subselect. How

Maybe - there have been patches for 7.3 after 7.4 was released. It
depends if any serious bugs are found.

The official answer is when it's ready. If I were a betting man, I'd
be happy

Here's what I have, I read a couple of these settings on various lists

Also, if you change ODBC settings you have to

You can get a snapshot of the 7.4 stable cvs if there is some post 7.4.6
fix you are interested in, before there is a 7.4.7 release.
