Hi,
Is there a simple way to display the create statements of SA Tables? If I do a
my_table.create(), some SQL is created and executed, is there a way to find
retrieve this as a string without creating the table?
Best Regards,

Good day community.
I don't know whether it is a good place to asc.
I've used sqlalchemy with turbogears and there were no problems. Easy
and strateforward. I've got lots of tables with lots of TableClasses
where I implement application logic.
Now I'm trying to use sqlalchemy with twisted. So

Hey all,
I've been looking through the documentation and searching google for
answers to this, but I can't seem to find a solution.
if I set meta.bind.echo=True, I can see the SQL statement that is
being generated when I call table.create(). Is there any way I can
easily grab this sql statement

In any case, thanks a lot! This is a real life saver.

Setup: (Problem statement near the bottom)
In my Pylons app, I have three separate models: Customer, TPPAnswer,

TPPAnswer is many-to-one Customer

Both have backreferences (so saq.customer and customer.saqs)
Currently, I have them defined in

Wow,
Hello,
I have a table that stores binary file data in one column and
information about the file (file name, mime type, sha1 sum, etc) in
the other columns.
Currently when I use the mapped class, it loads the file data (adds to
network and memory load). What I would like to do is check the sha1
Sounds like you want deferred loading for the column:

Coming from a pure SQL background I'm starting to get familiar with
all this new ORM and SQLAlchemy terminology. It's worth it though, the
code is so much cleaner and more maintainable than stringing together
huge complicated SQL
I started off with using only the SQL-API part of SA myself, but the ORM is
way too good to ignore, and I've since converted piles of code over to using
the ORM, typically with a 50% loss in lines of code and while getting much
better code reuse.
The query as a mapper-aware select orientation of
20 matches
