Hi!
I recently needed to use the select ... into ... construct to build a temp
table in Redshift. I used the
recipe https://bitbucket.org/zzzeek/sqlalchemy/wiki/UsageRecipes/SelectInto
here to get a good idea of how to go about this, and was wondering if I
should contribute the final working

Hi,
I want to create a custom type for TINYINT and DOUBLE.
I've defined them as custom types.
I want to use with_variant for them, so that in sqlite they print out as
TINYINT and DOUBLE.
But I also want them to use the variants defined for other databases, like
Oracle and Postgres.
The
I should add, please specify which backend you're using and what DDL
sequence you are looking to emit.

I've updated the documentation and in a few hours it should be up at

Oh, it's perfect for me if I can use bases for bindings.
Thank you

Hi,
I find that `UniqueConstraint` from `sqlachemy` and
`op.create_unique_constraint` by `alembic`, it cannot handle multiple
columns that contain null values.
I saw we can solve using SQL commands via some tricky ways like creating
unique index and coalesce, do we have some ways using

I have many classes, so it's seems a better idea to use something like that
(but I don't know what exactly is this registry, and why it's a WeakRef
dict) :
binding = {cls: engine for cls in Base._decl_class_registry.values()}
If not, maybe I can use the second approach, overloading Session,

Hi,
I'm using a schema with multiple DB, like :
engine1 = create_engine("mysql://localhost/{db}?charset=utf8".format(db=db1
))
engine2 = create_engine("mysql://localhost/{db}?charset=utf8".format(db=db2
))
Then I use automap and reflection to generate mapping of all classes needed.
Sometime, I
Thanks a lot Mike!
