Hi,


I have learnt that Hibernate uses "unsaved-value" property of "id" element to determine wether to insert or update a row.

How can we make Hibernate use a different attribute rather than id to determine wether to insert or update a row.

For example my data class is

public Customer
{

private String custRef = "";
private String saveMode= "";
private String address= "";

}

Database table has two columns (CUST_REF and ADDRESS).

I need hibernate to use the value of saveMode attribute of Customer class to determin wether to insert or update.

Can we do this with Hibernate.

Thanking You,
Chamal.
