1.2.17 [orm] [feature] Added new event hooks QueryEvents.before_compile_update() and QueryEvents.before_compile_delete() which complement QueryEvents.before_compile() in the case of the Query.update() and Query.delete() methods. [orm] [bug] Fixed issue where when using single-table inheritance in conjunction with a joined inheritance hierarchy that uses “with polymorphic” loading, the “single table criteria” for that single-table entity could get confused for that of other entities from the same hierarchy used in the same query.The adaption of the “single table criteria” is made more specific to the target entity to avoid it accidentally getting adapted to other tables in the query. [postgresql] [bug] Revised the query used when reflecting CHECK constraints to make use of the pg_get_constraintdef function, as the consrc column is being deprecated in PG 12. Thanks to John A Stevenson for the tip. [oracle] [bug] Fixed regression in integer precision logic due to the refactor of the cx_Oracle dialect in 1.2. We now no longer apply the cx_Oracle.NATIVE_INT type to result columns sending integer values (detected as positive precision with scale ==0) which encounters integer overflow issues with values that go beyond the 32 bit boundary. Instead, the output variable is left untyped so that cx_Oracle can choose the best option |
