Hi Chris, others,
https://bugs.eclipse.org/bugs/show_bug.cgi?id=340329
we got the requirement to allow overriding the CREATE TABLE keywords in DDL in a table-specific way to leverage special database features. Xu has proposed to introduce a creation-prefix attribute to the table-mappings of eclipselink-orm.xml - analogously to https://bugs.eclipse.org/bugs/show_bug.cgi?id=214519. Please find attached a revised proposal including test for this enhancement.
I you are OK with this feature, I would go ahead and check it in.
-Adrian
PS.
Alternatively, I could consider to specify additional requirements on the DDL using @Properties/@Property annotations. Then, one could add hese properties to the TableDefinition, redirect rendering of CREATE TABLE statements to the DatabasePlatform and render the statement in a database-vendor specific way according to the properties recognized by the vendor.
E.g.:
@Table(name=”MY_TABLE”)
@Property(“mysql.jdbc.engine”, “InnoDB”)
@Entity
Public class MyEntity
This, however, would obsolete the creation-suffix just introduced in 2.2 ;-).
