Hi,

I have a class with a calculated field:

Code:

class MyClass {
  ...
  private Integer total;

  public Integer getTotal() {
    ... some calculations...
    return v;
  }
  ...
}

"total" is not a database field. It's just a calculated property.
Can I use this property in a Hibernate query like this:

Code:

select m.total from MyClass m

And if this is possible, how can I map the property in MyClass.hbm.xml file ?

Thanks a lot.

If the calculations can be done by the database you can map it using a formula: <property name="total" formula="....." >.
