NHibernate Query using QueryOver HQL

Question

I am writing the follow as an NHibernate Query but cannot find a solution using QueryOver as HQL: -

IQuery query = SessionFactoryContext.GetCurrentSession()
    .CreateSQLQuery(
@"SELECT s.UserID,
    Username,
    Email,Password,
    FirstName,
    LastName,
    Address1,
    Address2,
    City,
    County,
    PostalCode,
    Country 
FROM [dbl].[dbo].[User] s 
    LEFT OUTER JOIN [dbl].[dbo].[groupmembership] g ON s.UserrID = g.UserrID 
WHERE g.UserID IS NULL 
    OR (g.GroupID NOT IN (" + groupID + ")  )")

    .SetResultTransformer(Transformers.AliasToBean(typeof(User)));

return (IList<Subscriber>)query.List<User>();

Is there any way possible that this can be written as an NHibernate query?

Many thanks for your help,

Answer 1

.CreateSQLQuery(
    @"FROM User u left join u.GroupMembership g
    WHERE g.User is null
      OR g.GroupId not in (:groupids)"
.SetParameterList("groupids", groupIds)
.List<User>();

Given that GroupMembership is a property of user and User and GroupId are properties of the GroupMembership. (If GroupId is the primary key, it can be simplified).
