conventions that include the token ``%(column_0_name)s``; the
constraint expression is scanned for columns.  Additionally,
naming conventions for check constraints that don't include the
``%(constraint_name)s`` token will now work for :class:`.SchemaType`-
generated constraints, such as those of :class:`.Boolean` and
:class:`.Enum`; this stopped working in 0.9.7 due to :ticket:`3067`.
fixes #3299

the logic used to link a :class:`.ForeignKey` to its parent could fail
when the foreign key used "link_to_name=True" in conjunction with
a target :class:`.Table` that would not receive its parent column until
later, such as within a reflection + "useexisting" scenario,
if the target column in fact had a key value different from its name,
as would occur in reflection if column reflect events were used to
alter the .key of reflected :class:`.Column` objects so that the
link_to_name becomes significant.  Also repaired support for column
type via FK transmission in a similar way when target columns had a
different key and were referenced using link_to_name.
fixes #3298

to complement the :attr:`.Table.foreign_keys` collection,
as well as :attr:`.ForeignKeyConstraint.referred_table`.

- fix "temporary_tables" requirement

:class:`.CheckConstraint` associated with a :class:`.Boolean`
or :class:`.Enum` type object would be doubled in the target table.
The copy process now tracks the production of this constraint object
as local to a type object.
fixes #3260

collection has been made consistent; this attribute is now a
:class:`.ColumnCollection` like that of all other constraints and
is initialized at the point when the constraint is associated with
a :class:`.Table`.
fixes #3243
