    Description

      With MySQL 8 (e.g. 8.0.19), MySQL57Dialect is selected instead of MySQL8Dialect. Wrote a test that was examining the connection metadata:

      ... INFO ... HHH000400: Using dialect: org.hibernate.dialect.MySQL57Dialect
...
... INFO ... Database server : MySQL 8.0.19
... INFO ... Database driver : MySQL Connector/J mysql-connector-java-8.0.19 (Revision: a0ca826f5cdf51a98356fdfb1bf251eb042f80bf)

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
