In the NHibernate XML document that contains the O/R mappings I have defined in the class element the atribute dynamic-insert = "true". Why the hibernate Insert SQL statement contains all the columns of my database table?.
I am using the NHibernate version : 0.8.3.0
Thanks a lot for any Help!!!

Can you give us more details? A mapping, a class and a debug log would be nice, so that we know what's happening.

Sergey,

I have seen this too. I will post my mappings and debug tomorrow.

Dear Sergey,
Here is the information that you need
Thanks in advance!!!

Ok, the problem is that when determining whether to insert a property or not, property values are compared to null, and none of your properties are actually null. It doesn't work for Nullable types either, since those are never equal to null (Nullable<something>.Default is a non-null object). If you need this functionality to work for Nullables, submit an improvement request to JIRA, we'll try to do something about it.
