In your example, you have a many-to-many relationship for territories and employees.
You used a Set in the Territory mapping file, and a bag in the employee mapping file.

Don’t you need to set one of them with the inverse=true attribute? To tell nhibernate which entity collection to use when their is a change?

nope, i don’t really believe in them

Curious, did you use any tools for generating your mappings?

I am new to NHIbernate.
Can anybody tellme how to do mapping / solve the current situation..

Product Table Category Table

productid categoryId
productname category
productdescription
category{string type}

Current Window: Product.Xaml [iam binding product entity to this form/window]

and my requirement is while accessing product entity from product table i need to access all categories from category table.So that it will be binded to a dropdownlist. is it possible? or i need to bind categories programmatically after loaded product entity ?

“from Employees e where e.Orders.OrderLines.Discount > 5″

…and I know that won’t compile, because that demonstrates what I’m stuck trying to do. I was hoping your fantastic Northwind solution which give me the answer.

class name=”Table1Class” table=”Table1″
set name=”Table3s” cascade=”save-update” table=”Table3″
key column=”Table1ID”
composite-element class=”Table3Class”
property name=”SortOrder”
many-to-one name=”Table2Class” column=”Table2ID”
/composite-element
/set
/class

I can be wrong though

I have a question i can google the answer! So i am hoping you may know.

I have a classic many-to-many situation in my database.

Table1(id|…) === Table3([id|table1.id|table2.id|sortOrder])=== Table2(id|…)

I have mapped this to my classes and this is working fine with each entity containing a collection of the other one.

however i have a column on my join table3 (sort order). And i dont know how to get hibernate to map this onto either entity.

Suggestion would be welcome. I hope i have explained the situation clearly enough.
