Hi all,

I am trying to set up a unique constraint on more than one column, But the hb2m2ddl script keeps on bombing:

@Table(uniqueConstraints=
{@UniqueConstraint(columnNames={"customer","run"})})

org.hibernate.AnnotationException: Unable to create unique key constraint (customer, run) on table Billing: customer not found

The column customer does exists. I am using MySQL. Any ideas?

thanks

If you are using @Column annotation, defined name, try to use defined name insteed attribute name, can solve your issue.
