Steve Ebersole commented on HHH-4553:
-------------------------------------
Clarification, the support for "global quoted-identifiers" was added to core
which is enabled by the org.hibernate.cfg.Environment#GLOBALLY_QUOTED_IDENTIFIERS option.
Still need to account for the 'bridge' where EM (or whatever) sees
<delimited-identifiers/> in persistence.xml and enables that config option.
Hibernate doesn't support official JPA2 escape char for table
name

Key: HHH-4553
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-4553
Project: Hibernate Core
Issue Type: Sub-task
Affects Versions: 3.5.0-Beta-2
Environment: Oracle 9i
Derby
Reporter: Julien HENRY
Assignee: Steve Ebersole
Fix For: 3.5
Time Spent: 6 hours, 35 minutes
Remaining Estimate: 0 minutes
One of the table of my schema is named FUNCTION. As it is a reserved name with Derby
(used for my JUnit tests), I have escaped the table name to make it works with Derby (as
specified by JPA2 spec $2.13):
@Entity
@Table(name="\"FUNCTION\"")
public class Function {
//...
}
My JUnit tests are working fine, then I tried to connect to my Oracle DB, and I have
enabled schema validation:
<property name="hibernate.hbm2ddl.auto" value="validate"/>
But I got an exception as Hibernate is looking for a table with name "FUNCTION"
in Oracle metadata.
Caused by: org.hibernate.HibernateException: Missing table: "FUNCTION"

This is not specific to Oracle, because when I change:
<property name="hibernate.hbm2ddl.auto" value="create"/>
by
<property name="hibernate.hbm2ddl.auto" value="validate"/>
in my JUnit tests, I have the same issue with the embedded Derby DB.
Using Hibernate specific ` as quote works fine:
@Entity
@Table(name="`FUNCTION`")
public class Function {
//...
}
The issue can be easily fixed in Table.setName(String name). Replace:
if ( name.charAt( 0 ) == '`' ) {
by
if ( name.charAt( 0 ) == '"' ) {
or if you want to keep backward compatibility:
if ( name.charAt( 0 ) == '`' || name.charAt( 0 ) == '"' ) {
