Hi, I have a one-to-many relationship based on a join table defined this way:


Code:

@OneToMany(targetEntity = SoftGenre.class, fetch=FetchType.LAZY)
   @LazyCollection(LazyCollectionOption.EXTRA)
   @JoinTable(name = "PROGRAMME_FEATURE",
         joinColumns = { @JoinColumn(name = "PROGRAMMEID", referencedColumnName="PROGRAMME_ID", unique=false, nullable=false, insertable=false,updatable=false ) },
         inverseJoinColumns = { @JoinColumn(name = "WORD", referencedColumnName="SOFTGENREID", unique=false, nullable=false, insertable=false,updatable=false) })


The column PROGRAMME_ID of the source entity is not a PK (and is not UNIQUE).
When running hbm2ddl to create/update my schema, a UNIQUE constraint is created for this column, even when it's annotated as unique=false.

How can I solve this?

Thanks,
Juan

With only a vague picture of what you are doing, I'm guessing here:
If PROGRAMME_ID is not unique, isn't this a many-to-many rather than a one-to-many?

it is, but I'm only interested in one side of the relationship and it's about read only tables.

Thanks,
Juan
