Hi All,

i'm using NHibernate in my project(C# Winforms Application). I have a requirment to populate some data in the database(SQLserver) with data integrity.

I have two tables.

EMPLOYEE
EmpId
Name

EMPLOYEEADDRESS
EmpId
Address
Addresstype.

The employee employeeaddress relationship is one t many. In a single transaction I want to insert one employee record in employee table and multiple address for same employee in employeeAddress table.

Can anyone help me


Thanking you
Satheesh

ISession.BeginTransaction and ITransaction.Commit() or ITransaction.Rollback()

I can populate the data in two tables with different transactions. But in a single transaction i'm not able to, so the data integrity will lost.

I want to save all the data at the same time other wise roll back the transaction

Please give me some samples with with an example i mentioned in the question.

It is hard to understand where is Your problem. But usual transaction handling code is:



You should read the NHibernate documentation, there is some information...

Gert

i have Two objects
Member (mId,mName)
memberAddress(aId(auto generated in db),mId,Address,addresstype)


Member mr=new Member();
memberAddress [] m=new memberAddress[3];
mr.mId=1;
mr.mName="Sam";
memberAddress m1=new memberAddress();
memberAddress m2=new memberAddress();
m1.mId=1;
m1.address="mm@m.com";
m1.type="Mail";
m2.mId=1;
m2.address="#888";
m2.type="Home";
m[0]=m1;
m[1]=m2;
mem.SaveMember(m,mr);

and my save member mthod is

public void SaveMember(memberAddress [] address,Member mem)
{
ITransaction tx = null;
try
{
if(!session.IsConnected)
{
session.Reconnect();
}

tx = session.BeginTransaction();
session.Save(mem);
foreach(memberAddress adr in address)
{
session.Save(adr);
}
tx.Commit();
session.Disconnect();

}
catch (Exception ex)
{
tx.Rollback();

session.Disconnect();
// handle exception
}
}



The above is my factory code and it is not working.

I think now you can understand more about my problem. I want to save one master table entry and and multiple child entries in a transaction.


Waiting for reply.


Thanks & Regards

Please explain "not working". Anyway, if Your session is opened, it may choose to flush any changed objects it knows about at any time.
