No, I don't think you're mistaken, especially if you want to use hints.
I tried this code again today with the django database connection (using
1.2 final), and it didn't work. This only works with cx_Oracle connections.
See
http://drumcoder.co.uk/blog/2010/apr/23/output-parameters-cx_oracle-and-plsql/
Ian said in the other thread: "Otherwise, you can get the
cx_Oracle cursor from cursor.cursor and use that directly." This sounds
like a way of being able to use the django connection but use the direct
cx_Oracle functionality.
Random thought - have you tried sqlalchemy? Does that have hint
support? I've never used it.

Thanks, I'll look into that. In the meantime, I managed to just use the
cursor from cx_Oracle (as in the example on Oracle site) and the code looks
slightly more elegant.
However, both "my" and yours solution suffer from the same defect imho --
that the ORM machinery of Django is unusable. We are back to manual mapping
of rows onto objects... Or -- am I mistaken?

Friends,
I'm in need of an implementation which calls for using bind variables (in
Oracle sense, not generic) in my SQL in a Django application.
Any experience with that, anyone?
Here's an example using bind variables to return output values from a
PL/SQL block.
>>> import cx_Oracle
>>> from django.db import connection
>>> cursor = connection.cursor()
>>> lOutput = cursor.var(cx_Oracle.STRING)
>>> cursor.execute("BEGIN %s := 'N'; END; ", [lOutput])
>>> print lOutput
<cx_Oracle.STRING with value None>
>>> print lOutput.getvalue()
None

There was a bug in Django that prevented this working (hence the None in
the code above) - it's fixed in Django 1.2. The full thread for this is

Hope that will help send you in the right direction.
