Fixed:How do I encode a <properties> mapping via Annot

I am converting my hbm.xml files to annotations. I cannot figure out how to convert the following:

Code:

         <properties name="Group" unique="true">
            <property name="aaa" column="aaa" type="string"/>
            <property name="bbb" column="bbb" type="int" not-null="true"/>
            <property name="ccc" column="ccc" type="int"/>
         </properties>

I have figured out the @Column definitions for aaa, bbb, and ccc, but how do I encode Group via annotations?

I've scoured the documentation and the forums.

Thanks

this is not possible today unfortunately. But if you're using properties just for the unique constraint, you can add that constraint in the database later on

Can I add the "ALTER TABLE x ADD UNIQUE " statement via an annotation
or do I have to manually add it to the DDL from

Code:

generateSchemaCreationScript(new MySQLDialect());

Thanks

Cool, I figured this out on my own, er, well at least by reading the docs:

Code:

@Table(name="table",
      uniqueConstraints = {@UniqueConstraint(columnNames={"aaa", "bbb", "ccc"})})

Cheers!
