Re: [eclipselink-dev] bug 340329 - table creation prefix

What would a typical prefix be? (is it really a prefix, or a replacement for "CREATE TABLE"? Is PREFIX the right terminology?)

When would someone choose to use a prefix?  Is this a MAXDB specific thing?

Hi Chris, others,

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 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.



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.



@Property(“mysql.jdbc.engine”, “InnoDB”)


Public class MyEntity

This, however, would obsolete the creation-suffix just introduced in 2.2 ;-).
