Thanks Mike! I just did that :) And is a pretty, simple and reusable

My environment is Python 3.2, SQLAlchemy 0.8, MySQL 5.5, and using

failure of the stored procedure. No record sets are

to figure out first how to do this with the plain DBAPI cursor, such as that of

Thanks again Mike. I was hoping in a way to log only statements, as my

Thanks for the quick reply.
As a workaround I wrapped the stored procedure in another stored procedure
that selects the return status. Now I am getting an 'Unread results
exception' when I execute.
Here is the code fragment (where self._engine is a SQLAlchemy engine):

Hi,
i use sqlalchemy to create a postgresql database. Within this database i
need a trigger. I found a recipe to declare triggers using DDL:
(this is declared inside class Absence)
trigger_ddl = DDL(

It is as simple as that:

with

The following SA code:

Michael,
As you suggested, I grabbed the underlying dbapi connection from the the
sqlalchemy connection and was able to get the result back in a somewhat
round about way (in the code that follows conn is a SQLAlchemy connection):
mysqlconn = conn.connection
cursor = mysqlconn.cursor()

IMHO, your best options are the SA examples (in

SA test units :)
Works great for me!

Hey, we have a lot of stored procedures that use out params like:
CREATE PROCEDURE create_stuff
@value INT,
@id INT OUTPUT
AS

INSERT into stuff ...

END
and when we rows = DBSession.execute() we reference these outparams via
row['@id'] and this is fine in

First, you must understand a simple concept: when you
