[ SOLVED ]JPA Question [message #1221891]

class ORDER {

@OneToMany
@JoinColumns({ @JoinColumn(name = "PARENT_ID", referencedColumnName = "ID"),
@JoinColumn(name = "TABLE_NAME", value="ORDER") })
private List<TableWithMultiKey> tableWithMultiKey;

}

I know that there is no "value" property...but something like this I need.

generated select should look like:

SELECT ID, FIELD1, FIELD2 FROM TableWithMultiKey WHERE PARENT_ID = 1 AND TABLE_NAME = 'ORDER';

...is it possible to implement a JoinColumn with a static value?

Is it possible to define a NamedQuery used by the @OneToMany call?

MySolution:

class ORDER {

@OneToMany
@JoinColumns({ @JoinColumn(name = "PARENT_ID", referencedColumnName = "ID"),
@JoinColumn(name = "'ORDER' as TABLE_NAME", referencedColumnName = "TABLE_NAME") })
private List<TableWithMultiKey> tableWithMultiKey;

}

... I simulate the SQL call and map to myself tablename. Rolling Eyes
