you should use TypeDecorator.load_dialect_impl(dialect), check the name of
the dialect,
Why the name rather than doing:
if isinstance(dialect,MySQLDialect):
?
then return either MSString(arguments) or
Yes, Congratulations Thank-you!

Hi All,
Are there any other docs for using and creating TypeDecorators than these:
http://www.sqlalchemy.org/docs/05/reference/sqlalchemy/types.html#custom-types
The following sections:
http://www.sqlalchemy.org/docs/05/reference/sqlalchemy/types.html#sqlalchemy.types.TypeDecorator.__init__
Congratulations Mike and contributors. This is an important milestone
in the evolution of SQLAlchemy. Thanks for all the hard work.

people do custom types for all sorts of things. In the case of the

how do I run some self-testing in sqlalchemy? I found this doc, but
it seems to be out of date??
http://svn.sqlalchemy.org/sqlalchemy/trunk/README.unittests
just for fun, i'm trying to run these tests inside IronPython, so any
pointers in that direction would be helpful also..
thx,

Hi, I'm writing a new custom dialect for a legacy database (Centura
SQLBase 7.5.1) for use in migrating to a new system over time.
Everything's gone pretty well, until I needed a join...
Whereas most dialects would create a statement such as:
SELECT T1.ID, T1.COL1, T2.COL2
FROM T1 JOIN T2
ON
I've run into some difficulty getting the ORM to fit into an existing
code base with some, I suppose, non-standard conventions.
One of the conventions is to not allow primary keys (auto-incremented
integers) to be exposed on the front-end servlet or template
but to maintain the original integer

What is the preferred method to have metadata.create_all() create
sequences? I tried to find something in the wiki but could not find
anything. For indexes you can do this:
schema.Index(public_event_idx, Event.workflow, Event.deleted)
but a similar statement for a sequence:

Sequence has a create() method but doesn't yet link into metadata.create_all()
without being assocaited with a Table. So yes you'd use DDL or in 0.6 the
CreateSequence() construct.

if you want MyClass.encrypted_id to be available in queries at the class
