How can i delete the content of the table using fluentnhibernate? - nhibernate

Question

I am using fluent nHibernate for my mappings as follow:
public class ContentTagMap: ClassMap<Employee>
{
public EmployeeMap()
{
Id(t => t.Id);
Map(t => t.Name);
HasManyToMany(t => t.Company);
}
}
public class CompanyMap: ClassMap<Company>
{
public HelpMap()
{
Id(h => h.Id);
Map(h => h.CompanyName).Length(6000);
Map(h => h.address).Length(6000);
HasManyToMany(h => h.Employee);
}
}
These mappings produce Employee Table ,Company Table and EmployeeToCompany Table
Employee Table
Id Name
1 John
2 MAX
Company Table
Id CompanyName address
1 HTC ABC
2 HTC2 India
EmployeeToCompany Table
Employee_Id Company_Id
1 1
2 1
How can I delete the employee with Id 1?

Unless I'm misunderstanding your question you should be asking:
How can i delete the content of the table using NHibernate?
Fluent NHibernate is only a tool to aid in the mapping of your entities. NHibernate is what you use to create, read, update and delete data. In any event:
9.5. Deleting persistent objects
ISession.Delete() will remove an object's state from the database. Of
course, your application might still hold a reference to it. So it's
best to think of Delete() as making a persistent instance transient.
From the NHibernate Documentation
You probably want to also define a Cascading style on your many to many relationship (HasManyToMany) in your mapping.
If you use Cascade.SaveUpdate in your many to many whenever you delete an entity on one side of the relationship it will delete that entity and any relationships. If you remove the association (ex. if you removed an Employee from a Company) it will only delete the relationship (EmployeeToCompany). This is what I've typically found to work in the case of many to many relationships.
Look at this article for more details on mapping and using a many to many relationship in Fluent NHibernate.
