Versioning does not work with actual DB (ORACLE)

Hi

I am replicating this video series using ORACLE DB and actual table in the ORACLE DB.

It all works fine, until I add 

@Version
private Long version;

to the

@MappedSuperclass public abstract class BaseEntity {

When you do this, the Build will fail, because the app think that the ORACLE Table is missing a table field called Version.

Has this been tested against real DB? other than H2?

Thanks

Never Mind

I think I know why it is working here ... in the video ... the H2 is creating the table on the fly ... and hence it is adding the Version Column/Field to the table. therefore, the build with H2 will work.

However, this won't work in the real world unless you are authorized to alter the table design in your db. Unfortunately, Not many of us have this luxury
