Hello,

I have a problem with the update of an entity.

Let's say i have a db with columns

id | content | date

and an entity Question with fields id, content, date

I have the annotation @org.hibernate.annotations.Entity(selectBeforeUpdate = true, dynamicUpdate = true)
When i populate my entity, let's say that date is null, but in db it has already a value, this being an update. Is there a way that hibernate could update only the content field and see that my date is null and not set the null value in db?

Thx in advanced.

i don't think this is possible. i think the question is, why is your date field null if it already has a value in the database? Hibernate tries to represent the objects in the Java world in the database. if you date is null in the Java world, Hibernate will transer this state in the database world. you should take care of your entity having the correct values.

I am using GWT-EXt as my frontend fmw. I am making an edit into a grid panel. So i don't pass to my server all the values from that grid (one being date). So when i populate my entity the date field is null. I was searching for a solution to bypass this problem without making a select before update.
