now, I'm using it like this:

Hi,
Reading through the docs, I could not find out how to tell the cardinality
of an object of type sqlalchemy.orm.properties.RelationshipProperty, i.e.
whether it is one-to-many, many-to-one or many-to-many. Mostly, I just
need to know whether a relationship refers to just one object or a

Thank you. That works great. And thanks for the explanation.

I found the missing space before literal_processor in my earlier listing, poor
font selection hid that pretty well - still not sure why I couldn't see that
earlier apologies again for that post.
The new listing below now runs to completion but literal_processor method is
not called for my UDT
like this:
class LiteralBindParam(BindParameter):
pass
@compiles(LiteralBindParam)
def literal_bind(element, compiler, **kw):
kw['literal_binds'] = True
return compiler.visit_bindparam(element, **kw)
class ArrayType(UserDefinedType):
def get_col_spec(self):
return ARRAY
Thanks! ... this is working nicely.
With a bit of customization this gives me an interim solution for passing lists
to stored procs using Oracle dialect.
I'm still hoping to find a way to bind array parameters outside of PL/SQL
through cx_Oracle later.

From:
you know if you just want to spit out a string and don’t mind calling a
function it’s much easier than that:
from sqlalchemy import literal_column
def oracle_array(arr):
return literal_column(int_array( + , .join(str(v) for v in arr) + )”)
ret =
Thanks - makes sense.
I have a pre-existing need to treat these arrays as columns in some instances,
so I think there's merit in the more complex solution using UDT.
Anticipated eventual use of ArrayType is something like:
class MyClass(Base):
__tablename__ = 'test'
# Columns
Hello,
I'm new to SQLAlchemy and have searched high and low for a solution to my

apply the 'order by' clause dynamically (both the column and the
direction). So a 'static' version of my query would be:

everything in python is ultimately in a namespace, the names are strings, the
values are the objects.
like if you had “myapp.model” as a module, and in that module were Study and
Site, you could say:
from myapp import model
Study = getattr(model, “Study”)
same thing.

I don't know if this is what you're thinking, but you can also just build a
