Do you need to use Expression.Sql? Couldn’t Expression.Eq work for you?

Reference Criteria Queries

Sample code:

IList cats = sess.CreateCriteria(typeof(Cat))
    .Add( Expression.Like("Name", "Fritz%") )
    .Add( Expression.Or(
        Expression.Eq( "Age", 0 ), //<---- here is the one you check for int equality
        Expression.IsNull("Age")
    ) )
    .List();
