Hello,
I am having an issue with nullable fields. I have specified the
valuetypes as being nullable, respectively DateTime? and int?. The
constructor of the class sets these values to null as well. My
mapping is as such:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
assembly="TEAMS_ORM">
<class name ="TEAMS_ORM.CWTRatingGroup,TEAMS_ORM"
table="tblCWTRatingGroups">
<id name="Id" column="Id" type="Int32" unsaved-value="-1">
<generator class="native" />
</id>
<property name="Name" column="Name" length="50" type="String"
not-
null="true" unique="true" />
<property name="UserAdded" column="UserAdded" type="Int32" not-
null="true" />
<property name="DateAdded" column="DateAdded" type="DateTime"
not-
null="true" />
<property name="UserEdited" column="UserEdited" type="Int32"
not-
null="false" />
<property name="DateEdited" column="DateEdited" type="DateTime"
not-
null="false" />
</class>
</hibernate-mapping>
UserEdited and DateEdited are the required fields. When I make
updates or saves to the db it will successfully pass nulls. However
when it retrieves from the DB and the fields are NULL it populates the
fields with arbitrary values however I need them to be null. This is
my retrieve query:
return (List<CWTRatingGroup>)session.CreateQuery("select from
TEAMS_ORM.CWTRatingGroup").List<CWTRatingGroup>();
How do I achieve this?
Thank you in advance,
Josh
