How Do I Delete a Business Entity Instance?

There are a number of ways to delete entities.

1. Delete an instance that you have a reference to:

   
   person.delete();
   

2. Delete an instance where you have only its Id:

   
   delete(personId);
   

3. Delete the results of a query

   
   Query query = createQuery("from Person person where exists ( "
       + " from PersonName as perName where person = perName.id.person and "
       + "perName.isPrimaryName = :systemBool and perName.entityName "
       + "like :name)");
    query.bindLikableString("name", "ABC", 64);
    query.bindBoolean("systemBool", com.splwg.base.api.datatypes.Bool.TRUE);
   
    long rowsDeleted = query.delete();
