Hi all,
I have some troubles creating my db schema with Oracle. The problem is
on this column:
Column('cod_caratteristica_rischio', Unicode(10), index=True,
nullable=False)
It works fine in PostgreSQL but when I try it on Oracle sa tries to
create an index with a name too long ( 30 char).
Hi,
I am having a bunch of classes that inherit from Function and all of
them should be compiled by a method annotated with @compiles.
class __base_function(Function):
def __init__(self, clause, *clauses, **kw):
self.clause = clause
Function.__init__(self,
Hi,
I've had a look through the docs and a quick look through the forum
here, and haven't been able to solve my problem. I'm using 0.4
The following works as expected.
q =
System.query().join('activity').group_by(model.System.id).add_column(func.max(Activity.id))
The add_column() recognises

The underlying column returns a Decimal object when queried regularly,
and when summed as follows:
select([ mytable.c.hours ])
Decimal(1.0)
select([ func.sum(mytable.c.hours) ])
Decimal(1.0)
...but when I sum it w/ an if statement, it returns a float:
select([ func.sum(func.if_(True,
I see, thank you, Mariano.

Hi,
So I thought I could write just one method, that is annotated with
@compiles(__base_function), but this does not work. I have to write a
method for each class that inherits from __base_function:
@compiles(wkt)
def compile_wkt(element, compiler, **kw):
return
That worked, thanks.

pep 249 specifies list of tuples for fetchmany() and fetchall()
Hrm, pep-249 seems to only specify sequence and sequence of
sequences for the fetch*() functions, specifying list of tuples only
as one possible example. Perhaps the C implementation of RowProxy is
being too strict here? I'm

Let's say I have a database with hundreds or even thousands of tables.
The table structure for this set of tables is *exactly* the same.
Furthermore, let's say the name of each table is predictable.
For example, something like:
tablename_2010_03_05
What I'd like to know is how to best manage

We're using SQLAlchemy sharding to partition accounts across a couple
of databases. We want to add more partitions, but first we need to
eliminate some unnecessary cross-partition queries.

Sure you didn't mean hundreds OF thousands? :)
