new copy is assigned the actual type of the compared column. Previously,
this logic would occur on the given :func:`.bindparam` in place.
Additionally, a similar process now occurs for :func:`.bindparam` constructs
- passed to :meth:`.ValuesBase.values` for a :class:`.Insert` or
- :class:`.Update` construct.
+ passed to :meth:`.ValuesBase.values` for an :class:`.Insert` or
+ :class:`.Update` construct, within the compilation phase of the
+ construct.
These are both subtle behavioral changes which may impact some
usages.
type of the enclosing expression has been improved in two ways. First, the
:func:`.bindparam` object is **copied** before the new type is assigned, so that
the given :func:`.bindparam` is not mutated in place. Secondly, this same
-operation occurs within the :meth:`.Values.values` method of :class:`.Insert`
-and :class:`.Update`.
