[hibernate-issues] [Hibernate-JIRA] Commented: (HBX-965) conditionally exclude catalog in H2MetaDataDialect

Dan Allen commented on HBX-965:
-------------------------------
However, I still question whether the H2 catalog should be declared at all. Declaring a
catalog results in it being put in the entity classes and that ties the entity classes to
H2. There are no catalogs in H2 (other than the default one), so it isn't really
needed. Here is what is created:
@Entity
@Table(name = "ROLE", catalog = "H2",
uniqueConstraints = @UniqueConstraint(columnNames = "NAME"))
public class Role implements java.io.Serializable {
}
conditionally exclude catalog in H2MetaDataDialect

Key: HBX-965
URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-965
Project: Hibernate Tools
Issue Type: Improvement
Components: reverse-engineer
Affects Versions: 3.2beta10
Environment: H2 1.0 (2007-06-17) and H2 1.0 (2007-07-12)
Reporter: Dan Allen
Priority: Minor
Attachments: HBX-965-v1.txt
Original Estimate: 1 hour
Remaining Estimate: 1 hour
Prior to build 55 (aka version 1.0 2007-07-12), the H2 database did not understand a
query that included the catalog name. For instance, if you had a table called EMPLOYEE in
the PUBLIC schema, H2.PUBLIC.EMPLOYEE would not work. After build 55, H2 understands this
query.
However, this brings up a different issue. You cannot create catalogs in H2, so really
the H2 catalog is just a bogus place holder. That has to make you wonder if putting the
catalog in the reverse engineering dialect is even wise. It makes the hbm2java generated
classes very non-portable. This debate is a bit of a fuzzy area for me.
