Hi all,
Is there any plan to add kerberos authentication to the sybase engine in
sqlalchemy?
I've implemented it but it's using the creator parameter of the create_engine
function, which is ok, but in certain circumstances when the application using
sqlalchemy uses configuration from a text
you should access column names via lower case
i.e.
columns = 'projectid', 'program', 'progmanger']

if you want to show me how that's done with your DBAPI (what DBAPI is this?),
sure, though if its something that you pass in via **kw to DBAPI.connect(), you
can already do that by passing connect_args to create_engine(), or adding them
onto the querystring db://...?foo=bar.

Thank you for the response. However, that is not the problem. If I do
update = table.update(project.c.ProjectID=='project-name', values =
{project.c.ProjectID:'program'})
print update
update.execute()
everything works fine.
if I do this:

I mean there must be since this is necessary for any application
needing to modify a database where generally tables are accessed
dynamically.

I think I know what the problem is. You need to use freetds version 7.0 or
8.0. If I set mine down to 4.2, I get your goofy results.
