Whooops. the problem in coming on the box which is running mysqldb1.2.0.
Actually it's a non-upgraded server with mysqldb 1.2.0. I was looking at the
code on my box which contains 1.2.2.
But I am sure that even with mysqldb 1.2.0 the existing SA version was
working fine. and that's why

Hi,
I am using sqlalchemy like this:
class Entry: pass
table1 = sqa.Table('table1', meta, autoload=True) # this table has
primary key 'id'
table2 = sqa.Table('table2', meta, sqa.Column('table1_id',
sqa.Integer,
Is there a different way to do this that's compatible with both
versions, or is there a new 0.4 way of doing this, or have I just been
doing something wrong all along and only 0.4 is catching it?
DateTime objects in sqlite currently expect a datetime.datetime
object, and not a string.

even though mysql is configured to cascade deletes for this
relationship, SA needs to be told about it so that it doesn't prevent
it from cascading by first nulling the foreign key?

Hello,
I am setting up a website with existing database using turbogears.
Database is in mysql.
I am using sqlalchemy but I'm having problems with choosing the mapper?
There is around 20 tables with a lot of foreign key, compound keys and
alternative keys.
Which mapper do I use?
Can you point

I've seen some of the Elixir info and thought it was too new to start
using just yet.
How hard is it to transition from ActiveMapper to Elixir, given a
moderately sized model and a moderate amount of access by controllers?
If I go with direct access to SA API in model, where do the
i have a premade filtering clause and give it to a query.select at
runtime. Sometimes its a simple x == 13 expression, another time it
is a full sql-construct like polymorphic_union().
in 0.3 all went into .select(), but in 0.4 these 2 kinds seems split
between .from_statement and .filter.

because we are going for more explicitness and less magic. when you
start having methods that accept five different things, then people
get confused which methods to use for what, it gets harder to check
for correct arguments, etc.
also, select_from() and from_statement() are not really
hello -
you generally use mapper() and relation() to set up how you'd like
your classes to correspond to your table relationships. as far as
compound keys, if they are defined with a primary key constraint you
shouldn't have to worry about them.
if you need to tell a mapper about some other
Hi,
I have a strange behavior (well, a blocking issue) on both sqlite and
mssql with unicode strings. It inserting a empty unicode string, it's
not encoded before being sent, while a non-empty string get encoded
correctly.
With sqlite it's not a problem, but with mssql it leads to a Invalid

0.4 has been in the trunk for a couple of weeks now (it was announced

Hi,
I'm reading the documentation on SQL Alchemy, but perhaps I'm missing
something here ... I need to join multiple tables, table1 with table2
and table1 again.
So, in SQL, I'd do something like:
select * from t1 join t2 on t1.b = t2.c join t1 t3 on t1.a = t3.a;
Yeah, it doesn't make much
we've never added this particular construct since its usually used in
migration scripts that are written as hand-coded SQL. ticket #722 was
recently added for this feature add. for now, you can enter it using
text() and theres also a workaround mentioned in that ticket.
hi Vetle -
the Table object supports a join() method, which can be called in a
chain, i.e.
table1.join(table2).join(table3)...
if you need to specify the ON part of the join, its the second
argument to join() (below illustrated with two joins back to table1):
table1.join(table2,
