refine in_() check to use proper duck-typing for __clause_element__
Fixed regression caused by an internal code change in response to recent
Mypy releases that caused the very unusual case of a list of ORM-mapped
attribute expressions passed to :meth:`.ColumnOperators.in_` to no longer
be accepted.
in this commit we had to revisit d8dd28c42e where mypy typing
didn't accept ColumnOperartors. the type here is the _HasClauseElement[_T]

match ORM mapped cols to PK in interpret_returning_rows
Fixed bug in ORM "update with WHERE clause" feature where an explicit

to an assumption that the ORM mapped class featured the primary key columns

deprecate joinedload, subqueryload with DML; use correct statement
An ORM exception is raised if :func:`_orm.joinedload` or
:func:`_orm.subqueryload` are used as a top level option against a
statement that is not a SELECT statement, such as with an
``insert().returning()``. There are no JOINs in INSERT statements nor is
there a "subquery" that can be repurposed for subquery eager loading, and
for UPDATE/DELETE joinedload does not support these either, so it is never
appropriate for this use to pass silently.
Fixed issue where using eager loaders such as :func:`_orm.selectinload`
with additional criteria in combination with ORM DML such as
:func:`_sql.insert` with RETURNING would not correctly set up internal
contexts required for caching to work correctly, leading to incorrect
results.

revert SQLite CHECK constraint changes and add new tests
The changes made for SQLite CHECK constraint reflection in versions 2.0.33
and 2.0.34 , :ticket:`11832` and :ticket:`11677`, have now been fully
reverted, as users continued to identify existing use cases that stopped
working after this change. For the moment, because SQLite does not
provide any consistent way of delivering information about CHECK
constraints, SQLAlchemy is limited in what CHECK constraint syntaxes can be
reflected, including that a CHECK constraint must be stated all on a
single, independent line (or inline on a column definition) without
newlines, tabs in the constraint definition or unusual characters in the
constraint name. Overall, reflection for SQLite is tailored towards being
able to reflect CREATE TABLE statements that were originally created by
SQLAlchemy DDL constructs. Long term work on a DDL parser that does not
rely upon regular expressions may eventually improve upon this situation.
A wide range of additional cross-dialect CHECK constraint reflection tests
have been added as it was also a bug that these changes did not trip any
existing tests.

server side condition with an idle transaction that then goes back into the

environments will have largely accommodated the setuptools change by
