EclipseLink & Cell Names with White Space [message #654471] Tue, 15 February 2011 22:38 Go to next message

Performing a normal query like
List<Contact> list = em.createNamedQuery("Contact.findAll").getResultList();
gets translated into
SELECT No_, Mitgl_ in Firmenmitgliedschaft, Telex Answer Back, Profession, [...]
which results in an java.sql.SQLException because of wrong syntax. Is there any way to deal with columns containing white spaces?

I got to use MS SQL here, so the normal way of doing such a query would be
SELECT No_, [Mitgl_ in Firmenmitgliedschaft], [Telex Answer Back], Profession, [...]
I set NATIVE_SQL and SQL Server in the persistence.xml, but it did not help for this issue...

Already found a solution/workaround:

If all the problematic column names get wrapped in the entity class, the problem disappears, for instance:
@Column(name = "[Mitgl_ in Firmenmitgliedschaft]")

In JPA2 there is an element in the orm.xml persistence meta-data,

<delimited-identifiers>

that will have all columns delimited to allow spaces/special chars/case.

I think using,

@Column(name = "\"Mitgl_ in Firmenmitgliedschaft\"")

will also work.
