orm
[orm] [bug] Fixed issue where referencing a CTE multiple times in conjunction with a polymorphic SELECT could result in multiple "clones" of the same CTE being constructed, which would then trigger these two CTEs as duplicates. To resolve, the two CTEs are deep-compared when this occurs to ensure that they are equivalent, then are treated as equivalent.

_sql.select()
construct that is passed a sole '*' argument forSELECT *
, either via string,_sql.text()
, or_sql.literal_column()
, will be interpreted as a Core-level SQL statement rather than as an ORM level statement. This is so that the*
, when expanded to match any number of columns, will result in all columns returned in the result. the ORM- level interpretation of_sql.select()

is used.If
'*
is used amongst other expressions simultaneously with an ORM statement, an error is raised as this can't be interpreted correctly by the ORM.References: #8235
orm declarative
[orm] [declarative] [bug] Fixed issue where a hierarchy of classes set up as an abstract or mixin declarative classes could not declare standalone columns on a superclass that would then be copied correctly to a
_orm.declared_attr
callable that wanted to make use of them on a descendant class.References: #8190
engine
- [engine] [usecase] Implemented new
_engine.Connection.execution_options.yield_per
execution option for_engine.Connection
in Core, to mirror that of the sameyield_per <orm_queryguide_yield_per>
option available in the ORM. The option sets both the_engine.Connection.execution_options.stream_results
option at the same time as invoking_engine.Result.yield_per()
, to provide the most common streaming result configuration which also mirrors that of the
