Hi All,
I guess this question would also be applicable to the lists of the rdb
in question but since SA is going to have to help to I thought I'd ask

Okay, so if I have a table that contains a blob-ish field containing
something like a 20Mb PDF per row (I'm not sure this is a good

I have numerical values assigned to user in a table, I have query the
table, sort the table in a descending order and then return the value
of a certain user with his position/rank in the table.Could someone
give me a leg up?
Thanks

Hello!
I have a similar error with SA 4.1.0 and turbogears.

I don't know what the design decisions were regarding the Sequence
object, so bear with my ignorance for a moment here.
I played with SQLAlchemy in conjunction with Pylons. I had code that
looked like this:
links_table = Table('links', metadata,
Column('id', types.Numeric(),
I have a table with a Date column. Why does a python datetime match
the value and a python date does not? For example:
# example table
institutions_table = Table('institutions', meta,
Column('id', Integer, primary_key=True),
Column('report_date', Date),
...
this works:
not sure, it depends on what kind of database youre using (and what
DBAPI) as well as the actual type of column is is on the database
side.

for a database which supports sequences, it will. It appears that for

Sorry,
Database is sqlite. From my understanding sqlite would store the value
as a string.
From running the following test it seems that the orignal type of
value stored (datetime vs date) is being maintained in sqlite
regardless of the Column type:

I should probably add that I'm curious if this is the desired
behavior. From my (relatively inexperienced) point of view it seems
that sqlalchemy should try to return whatever the programmer is
expecting as designated by the column type.

Same here on pymssql.
I tried it with 'start' as the only PK, and with both 'identifier' and
'start' as PK. Both work fine.
Are you sure your in-database tabledef matches your declared schema?
I've attached a script that works here. This one has both 'identifier' and
'start' set as PK.
