Hi,
Regarding the documentation about OpenJPA you can define a unique column
with something like that:
@Entity
@Table(name="ART", [EMAIL PROTECTED](columnNames="TITLE"))
public class Article {
...
}
And in XML
<entity class="org.mag.Article">
<table name="ART">
<unique-constraint>
<column-name>TITLE</column-name>
</unique-constraint>
</table>
...
</entity>
For more information see the "Unique Constraints" section [1]
