Notable Items

Data Definition - Create Table

• On an error in CREATE TEMPORARY TABLE ... SELECT, InnoDB internally aborted a transaction, while the server thought the transaction still existed. This caused various inconsistencies in the binary log, disappearing savepoints, and more. The issue was fixed differently in different versions. In 10.11.16, 11.4.10, 11.8.6, and 12.2.2, the transaction is consistently and completely rolled back if CREATE TEMPORARY TABLE ... SELECT fails with an error. In 12.3.1, there is no rollback at all. (MDEV-36787)
