[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-4553) Hibernate doesn't support official JPA2 escape char for table name

Steve Ebersole updated HHH-4553:
--------------------------------

         Assignee: Steve Ebersole
    Fix Version/s: 3.5

Actually I think the more correct solution is for the annotation binder to see the double-quotes in the table name and convert them to back-ticks.

> 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"

> 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 ) == '"' ) {
