Minor Description
when you specify columm table="empbean" in the xml file entity id or basic type when empbean is the default table name, the mapping tool generates extra foreign key field (eg.EmpBean_empid) in the table produced. This causes a SQL0203 (A reference to column name is ambiguous) on empid when you try to persist this entity.
