OK, I can see this case being a bit complex. I just wanted to be sure
I wasn't missing some mechanism for handling it.
Thanks!

When you create new columns, don't forget that you need to flip the
column declaration around
class Bar(Base):
foo = Column(String)
becomes
foo = Column('foo', String)
I'm using declarative with sqlalchemy-migrate just fine.

This is using SQLAlchemy 0.5.2.
I do hope there's something obvious that I missed...

But the code I was looking at is in mysql.py, so I was assuming this

OK, I guess that's re
I have some of my columns defined as Column('foo', Unicode). This
worked fine with MySQL, but a change made in r4705 appears to have
broken this. Prior to 4705, that would generate a TEXT column in the
create table. This was switched to just VARCHAR.
MySQL 5.0.45 does not accept VARCHAR without a
valid thought? Versant doesn't support SQL, most of its

That's great! I know how rough plane travel can be for some folks.
It'll be good to meet you there!
