Richard Zowalla created OPENJPA-3074:
----------------------------------------
Summary: Share the common code of MySQLDictionary and
MariaDBDictionary in a superclass and add the MySQL 8 reserved words
Key: OPENJPA-3074
URL: https://issues.apache.org/jira/browse/OPENJPA-3074
Project: OpenJPA
Issue Type: Improvement
Reporter: Richard Zowalla
Assignee: Richard Zowalla
Fix For: 4.2.0
MySQLDictionary and MariaDBDictionary both extend DBDictionary and duplicate
most of their code, as noted in the review of #297 (OPENJPA-2943). Move the
shared code into a common abstract superclass and keep the per-database
differences and defaults in the two subclasses. All public configuration fields
stay as they are.
MySQLDictionary also lacks the reserved words MySQL 8.0 added, such as RANK,
ROW_NUMBER, WINDOW and LATERAL. An entity attribute named rank therefore
produces a CREATE TABLE statement that fails on MySQL 8.4 and 9.x.
