Just to close my question:
I tweaked few settings for innodb and seems pretty good already.
The biggest is being: transaction_isolation = READ-COMMITTED
Of course not for everyone but for my needs, this works perfectly.
thanks

Hi,
I am using SQLAlchemy - 0.8.1
Background - I have a table event which has a flag 'is_deleted'. This
table has a composite primary key (sid,cid). There are many other tables
related to event that store information regarding that event - e.g.
iphdr. I want to give the user an option of

Thanks for the reply. I understand that update against multiple tables is
non-standard. However, I think I am trying to update only one table
(events).
The equivalent of what I am trying to do is

OK just trying to get my head around the issue - psycopg2's parser does not
have the backslashing issue right ?
psycopg2's parser is fine. the fix is committed in master / rel_0_8 branch,
thanks for the patch
I wish zope.transaction or something that replaced it would return a
Session subclass that replaces .commit and .rollback with calls to
transaction.commit and transaction.abort rather than raising an
exception with one and silently doing the wrong thing with the other :-/

You shouldn't need to write special code for this, have you tried changing
