I have posted this to the fluent nhibernate group but not got much
response so maybe this (modified) question will be better.
Basically I have a Person class from which I have two inherited
classes, Author and Borrower (it's a library system). The mapping I
have is below.
Now if I run the HQL "FROM Author a ORDER BY a.Name" it will return a
list of all Author and Borrower entities where I obviously just want a
list of authors. Please feel free to set me straight on this.
Thanks, Craig
