[eclipselink-users] @GeneratedValue Question
|
hi all
i just got this link
http://download-uk.oracle.com/docs/cd/B32110_01/web.1013/b28221/cmp30cfg001.htm#BCGDBFFA
and my @id implementation is look like this
@Id()
@GeneratedValue(generator="system-uuid")
@GenericGenerator(name="system-uuid", strategy = "uuid")
public String getId() {
return id;
}
and that is hibernate syntax
our last dicsussion that the recommendation is to implement table generator
but i got
Generated Id Table
A database table that the container uses to store generated primary
key values for entities. Typically shared by multiple entity types that
use table-based primary key generation. Each entity type will typically
use its own row in the table to generate the primary key values for
that entity class. Primary key values are positive integers.
Table Generator
A primary key generator, which you can reference by name, defined at
one of the package, class, method, or field level. The level at which
you define it will depend upon the desired visibility and sharing of
the generator. No scoping or visibility rules are actually enforced.
Oracle recommends that you define the generator at the level for which
it will be used.
This generator is based on a database tabl
both table sequencing
can give me the example of both case, when we use the table generator or generator id table
