Hello,
I discovered SQLAlchemy yesterday, and have been trying to figure out
if its worth using as I rewrite my clunky code to maintain sql records
of parameter values of expensive data structures (large numpy arrays)
stored in Python shelves.
It looks fantastic, but not sure yet that it is the
try func.yourfuncname(..) ?

Hi, I have been scouring the sqlalchemy 0.5 documentation and can't
seem to find information on how to execute UDFs. I am dealing with
the following scenario:
1. I create a UDF (for example, get_fav_id, which
its not working. make sure you do in fact have the onupdate
configured on the correct Column/Table, etc.

Hi,
The following code returns a list of tuples to python from the db,
corresponding to the values of the 'snpval_id' column in the table 'cell'.
I was wondering if there was an easy way to have it return a list of
values (in this case, integers) instead.

Hi all,
I try to set up a many-to-many relation with an association object.
But I want something not usual: I want the child object deleted when
not owned by any parent anymore.
This is for a messages/recipients relation: the message is useless
when everybody removed it from its mailbox!

i think i had similar configuration, and i did it like one link was
using default cascading, the other was just 'all'. but i'm not sure
if yours is same, and any way i got mine via trial and error.
do play with the cascade options. also i'm not sure if u apply some
cascade on a backref what
Is it planned for 0.6? or earlier?
Anyway thanks: I stop trying all the combinations right now! :)

I am using SA inside of a couple of scripts that use pyprocessing to
spawn off children. It looks like it's working, but occasionally I get
some really odd errors. Here are the basics of the app:
We are using the declarative layer, SA5, etc. At runtime, a parameter

I have a quick question. I am trying to make an index for my table in
MySQL. I have the line below:
Index('index_table_on_field', table.c.field)
I want to specify a length as in the SQL:
KEY `index_table_on_field` (`field`(255))
Where do I enter the value 255 in the SQLAlchemy syntax?
I have the table definition below:
urls = Table('url', meta,
Column('id', Integer(11), primary_key=True),
Column('address', Unicode(1024)),
Column('content', Unicode(255)),
mysql_engine='InnoDB'
)
This will make the SQL below:
CREATE TABLE `url` (
`id` int(11) NOT NULL
you should create a new engine per forked process, within the forked
process, and bind it to the session.Using the connection pool from
the parent process in a child fork does not produce behavior that's
defined in any way I'm aware of (apparently the connections travel
over for this
The declarative extension (sqlalchemy.ext.declarative) provides a
__init__ that takes keyword args for attributes (at least it does in
0.4).

I think this is configurable on the MySQL server directly, i.e.
default charset, otherwise you can set it via **{'mysql_DEFAULT
CHARSET':'utf8'} in your Table def.

I've always thought this format for the list comprehension was
particularly clean:

What is the best way to achieve the auto delete of the child then
