Hello,
I have a rather complicated query on a medium sized database (millions
of rows). One part of the query looks like the following :
SELECT
COUNT(sp.id),
COUNT(
(SELECT
sp.id
WHERE
sp.site_id IN (
SELECT
si.id
FROM

It doesn't work because more than one row are returned by the subquery
used in the expression ...

Thanks! That appears to have done it.

That's fixed it. Thanks very much.

Hi,
I just noticed that both 0.3.x and 0.4.x versions of SQLAlchemy print
compiled query for MySQL without binded parameters, so typical
printout for MySQL looks like
SELECT DISTINCT block.`Path` AS `block_Path` FROM tier0.block WHERE
block.`Path` LIKE %s
while doing the same with ORACLE
In the documentation I found
Note that from objects are automatically located within the columns
and whereclause ClauseElements
for the select() statement.
It is precisely the thing I do not want to.. no way to disable it .. ?
Thanks,
Julien

in fact all the problem is that I can't generate the following query:
SELECT xx.yy, (SELECT xx.yy WHERE cond) FROM foobar xx;
where xx.yy are the same columns
SQLAlchemy generates :
SELECT xx.yy, (SELECT xx.yy FROM foobar xx WHERE cond) FROM
So you're still disagreeing with Jason, who's quite explicitly saying
that SA's __init__ will blow up if it gets called. Which of you is right? :)

SA's __init__ does not blow up if it gets called. It just checks that
mappers are

I am very pleased to announce that version 0.5.2 of Elixir

available. As always, feedback is very welcome, preferably on Elixir
mailing list.
This is a minor bug fixes release (mostly restoring python 2.3 compatibility).

I'm having a strange caching problem when using SQLAlchemy with Apache
and mod_python. Using the ORM, I have a class that maps to a simple
table with two columns and no foreign keys. When I get an HTTP
request, I get the desired object by primary key and return the value
of the attribute that
