Hello all,
I have been using SQL Alchemy for sometime now in a turbo gears
project. Recently, i wanted to write a small piece of python code
which has to do a few DB operations on the same DB which is used by my
TG project. so i decided to use the existing model.py file.
to my delight, as soon

Michael,
I read the expression language tutorial and found the section on
bindparam. So, here's what I came up with:
idworks = Table(
'ps_ih_idworks', metadata,
Column('emplid', String(11), primary_key=True),
Column('date_acquired', Date),
RAW columns have a max of 2000 bytes (http://www.orafaq.com/wiki/
RAW ). you want to create your table with a BLOB column for more than
that.

mmh, cant really grasp what u want to do.
what are Line.* attributes?
.filter does and(), so this can be simplified:

the query itself or the objects it returns after execution?
q = query(Line).join( Fiber, ...condition ).filter()
if ... return q.filter( 123...)
else: return q.filter( 456...)
building that q is not expensive;
saving it is fine
My apologies - I forgot to mention the photo field is a LONG RAW and
that the table already exists.
In the table definition the field is now defined as Column

Hi ALL!
Does tometadata have to change foreign key schema name if it already
specified?
For example if I have column 'user_id' with 'system.users.id' FK -
tometadata change 'system' schema to SOME_SCHEMA. Is it ok, or
tometadata have to set schema to SOME_SCHEMA for street_id,
locality_id
I've got the following code to reflect an MS SQL 8 database using the
latest stable pyodbc, python 2.5, and SQLAlchemy 5.1:
engine = create_engine('mssql://userXXX:pass...@mydsn', echo=False)
meta = MetaData()
meta.bind = engine
artreqs = Table('tb_FSAR_Data_SampArtReq', meta, autoload=True,
send along what the CREATE TABLE for the table in question looks like.

The structure of the table is read when reflecting the table: it's likely
that an unusual column definition would trigger an error like this, and it
would be helpful to someone diagnosing the problem to
Hi,
I've got a query as follows:

this can be changed but the function still makes no sense. What if
you also said t3 = users.tometadata(metadata,
