Hibernate version: 2.13



I have added a new field to my table which is to be unique, but for new records I would like the new column to take the value of the generated id column as a default. I can update the existing data when I make the schema change, but would like to cover the creation of new records and don't think I can get the id in the constructor.

/**
* @hibernate.id generator-class="sequence"
* @return
*/
public long getId()
{
return id;
}

Is this possible please?

Thanks

I would like to set another field to use the property of the id field as a default, but is this possible as the id field will only be determined by the sequence at write time?

Any ideas, how best to achieve this please.

I do not really want to write a trigger at the db level, but can't think of anything else currently.

Thanks

Someone must have run into this situation before and not wanted to install a db trigger?

Any ideas to a hibernate way?

Thanks

You can change your ID setter to propagate id value to
another property if this is still null ( not set )

Thanks for your reply.

Will adding some code in the setId() method work seeing as the Id is based on a sequence?

I'll try this out, and see what happens.

Cheers

I guess so. AFAIR, hibernate first sets id and then saves object -
could work. BUt if I were you, I would place System.err.println()
into set id just to be sure...
