Hi,
I have a self-referential mapper that looks like that.
Basicially a tree of 'HierarchyNode' where the leafs are
'ArbeitsmittelHierarchyNode' (accessed through the '_tools' property)

'_children' : relation(
Hello,
partitioned tables in PostgreSQL don't report the correct number of
updated rows, so updates from a mapper fail. Reported by Antonio on
the postgresql-it mailing list.

as this issue just was mentioned the other day, the SA workaround
would be a dialect-level flag to
Could someone point me to the documentation about declaring and using
Sequence fields in Sqlalchemy? If there are no docs, could someone
give a rundown? I can imagine how it could be used, but I´ll be
working in the dark without documentation.
Thanks

For course not. As you can see from the traceback this happens on
the SA level (using a self-referential mapper).
then thats an ORM bug. you need to send me some sample code that
reproduces the error. the ORM uses Column-targeting in

Actually sane_rowcount is an effect: the cause is that the table is
partitioned. Would partitioned be a better name for the flag?
mmm maybe except the sane_rowcount flag is specifically a
workaround style flag and other situations

I cant speak authoritatively here at all since youve given me no

I am having an issue at work with a query that is passing in all of our
unit tests against SQLite and PostgreSQL, but is failing in MySQL. Here
is a short test case that will show the problem. Any help would be much
appreciated!

It appears to me that MySQL doesn't like it when you don't specify a
FROM in the subselect, whereas PostgreSQL and SQLite don't care.
Responding to myself, I have solved the problem. As it turns out, you
can force SQLAlchemy to generate a FROM for the subselect by

Sounds like the invalid cursor state bug that I thought might have been
fixed for pyodbc in r2729. Maybe not...

if you wrote your above statement directly in SQL, and you reference
an outer table in a subquery without putting the table in the
