I have several fields in my database tables typically the following:

CreateBy
CreateDateUTC
UpdateBy
UpdateDateUTC

The classes don't have these fields or information because they don't need to know about them They are for auditing.

Is there an easy way to do this in the mapping. Something like

<column name="UpdateBy" sql-type="varchar(50)" default="CurrentIdentity.Id"/>

<column name="UpdateDateDTC" sql-type="datetime" default="GetUTCDATE()"/>

I know this is a stretech but I don't like adding triggers to the dbase to do the same thing.
