[eclipselink-users] quoting problem with PostgreSQL

[Martin Geisse <mgeisse@xxxxxxx>]

Hello,

I am moving this here from the community forum since the forum isn't very active and there seems to be little overlap in the people posting.

With PostgreSQL, I have to double-quote all identifiers or they'll be implicitly lower-cased. I'd prefer to preserve case since "lastLoginAttemptIpAddress" is so much more readable than "lastloginattemptipaddress".

I have created an orm.xml file with (full contents below). That caused EclipseLink to quote most of the identifiers, but it specifically did not quote the column name when defining a foreign key constraint. How can I tell EL to quote all identifiers?

I have also tried using quotes in the explicitly specified table / column names to cause EL to quote identifiers. First and foremost, that doesn't work either -- same behavior. In addition to that, it forces me to specify names twice (in the annotation AND in the property accessor names) and in a manner that is invisible to refactoring tools. It also forces me to fix quoting at POJO level when it is actually a specific trait of the database system I am using.

Thank you in advance.

entity class:
----------------------------
@Entity
public class UserX {

   ...

   @Id
   @GeneratedValue(generator = "UserX_id_seq")
   @SequenceGenerator(name = "UserX_id_seq", allocationSize = 1)
   public int getId() { ... }

   ...

   @ManyToOne(fetch = FetchType.LAZY, optional = false)
   public UserX getModificationUser() { ... }

}
----------------------------


the generated query (note the missing quotes around the column name):
----------------------------
ALTER TABLE "UserX" ADD CONSTRAINT "FK_UserX_modificationUser_id" FOREIGN KEY (modificationUser_id) REFERENCES "UserX" (id)
