Sorry for double posting. I pressed "Send" before I was ready...
Please let me know if I'm doing something wrong here:
[code]
metadata = MetaData('sqlite:///first.sqlite')
table = Table('my_table', metadata, Column('text', Unicode(16)))
stmt = table.insert()
parameters=dict(text='Hello, World!')
print stmt.compile().params
print stmt.params(parameters).compile().params
[/code]
The first print gives:
{'text': None}
The second crashes with:
File "/tools/aticad/1.0/external/python-2.4.1/lib/python2.4/site-
packages/SQLAlchemy-0.5.0rc4-py2.4.egg/sqlalchemy/sql/expression.py",
line 3515, in _copy_internals
self.parameters = self.parameters.copy()
AttributeError: 'NoneType' object has no attribute 'copy'
After doing this patch:

I get {'text': None} for the second print too.
I took this directly from the docs at
sqlalchemy.sql.expression.Insert.params.
Should I use 0.4 instead? Is it more stable / less broken?
