Hello,
I am tryin to make the dynamic where clause using append_whereclause.
But how i can do that, For eg :
I have a==b and c in (1,2,3,4) or d like %s
So i made three sqlalchemy expression
1. a==b
2. c in (1,2,3,4) [ using in_]
3. d like %s [using like]
now i want this 3 to stuff in
Hi,
I've hit a problem very recently with autoloading of table info from
an oracle schema which I believe is caused by a problem inside the
_resolve_synonym method of oracle/base.py. I've googled around a bit
but didn't find this issue reported previously. It may well be a
problem with our db
Using sqlalchemy version 0.5.2, I've noticed that the sum method
seems to have been removed from Query :
session.query(MyClass).sum(MyClass.price)
'Query' object has no attribute 'sum'
I can't find this change documented anywhere : it was present in 0.4
as I recall.
Any reason for this ?

ha! got it! you were right, it's a vendor's python implementation
problem. the custom python runtime put an instrumentation layer on top
of other classes and that why it breaks :D
switched to the genuine python 2.3.5 and now it's fine :)

Hello,
Can validators be defined at table / mapper level? (Is it even a
good idea?)
I ask, since it's at the table definition layer that I define what
datatypes my columns have, so it seems natural to place the policing
function there as well.
a table level validator would

Can you post your solution?

Michael,
thanks for your reply! Unfortunately, I believe I have to use the
synonyms feature, because I cannot use the table owner's schema owner
to access the database. Everything works if I use the table owner's
schema (AINV_OWNER) but the db policies forbid this for production, so
I have to

If you have mapper definitions separate from classes, theres nothing
stopping you from adding attributes to the class over there, i.e.
mapper(MyClass, mytable)
MyClass.foo = some_validation_decorator(MyClass.foo)
Personally I wouldn't bother (then again I use declarative for everything
no chance :( legacy third party C extension libraries :(

Thanks! That is the what i want.
