[Hibernate-issues] [Hibernate-JIRA] Commented: (HBX-622) Allow ability to ignore Foreign Keys

[Michael S. (JIRA) <no...@at...>]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HBX-622?page=comments#action_23613 ] 

Michael Slattery commented on HBX-622:
--------------------------------------

I found a much better solution.  Set the property:   "hibernatetool.metadatadialect" to the class name of:

public class KeylessMetaDataDialect extends JDBCMetaDataDialect
{
  @Override
  public Iterator getExportedKeys(String catalog, String schema, String table)
  {
    return Collections.EMPTY_LIST.iterator();
  }
}

(I realize that extending a wrapper of MetaDataDialect would be better design)

> On the project I'm currently working on we want 1:1 POJO<->Table mapping without any relationships between the POJOs.  Although this is not a configuration that I would normally choose or recommend, in this case it is forced upon us be external architectural requirements.
> Currently in order to avoid relationships in your POJOs you have to reveng each table individually.  The attached patch is a proposed solution to allow the reveng to ignore relationships between tables when reverse engineering multiple tables at the same time.
> Note that the patch only supports this for ReverseEngineeringStrategy not for reveng.xml.
> I'm supplying the patch in the hope that it (or something similar) can be incorporated into the main code and in case anyone else has (unfortunately) similar requirements.
