Hello there. I'd like to use SQLalchemy with an existing db2 database

Hi,
I have a mapping between a table row and a python field, for which I have a

Is there a way that, i can validate the values in BLOB column (the
binary data) maps to a valid pickle string.
if I dump the data from the row to a file, will it be of any use?
select results into dumpfile '/tmp/blob_data.txt' from task_results
where task_id=1;

Hello SQLalchemy users,
I just wanted to share my latest project for profiling sqlalchemy applications.
It's an extremely simple library that hooks in via sqlalchemy's new eventing
system to give you really easy introspection, profiling and reporting.

Hello,
I've implemented a 'read' event for attributes, similar to 'set'. It's
called 'read' and not 'get' because it's fired only when data is fetched
from the database.
The implementation looks a bit crude to me, as I'm not so familiar with
sqlalchemy internals. (but this exercise did teach a

This simple construction does not change the content of the list after
commit, and it seems to me that it should.
Of course t.array = t.array + [1] works correctly.

Hi Michael,
i am intrested in writing a dialect for DB2. Is there any howto which
covers what is needed to start. Do you think we should write an
extension, or should this dialect in sqlalchemy itself?
Thanks in advance

I'm facing problems with mssql+pymssql: it seems that pymssql has poor

As a result there are some rounding differences between the values stored in
the database, and the values I get when querying through mssql+pymssql. And

If I merge() an object with a collection property, the backref's are
not set as they would be if I had assigned the collection to the
object.
I expected that this should occur. Is there rationale for not setting
backref's or would it be possible to make this change?
Thanks,

A persistent object doesn't populate an unloaded backref on a forward set
event. This is for efficiency so that when you do something like:
for b in Session.query(B):
b.a = some_a
it doesn't spend time loading the bs collection of some_a, which if you had
a lot of different some_a
