I have a following database structure.
I have already saved Buyer
in database. I have buyer id
. I have to save contact information of a buyer in the database, as I save contact in the database I also need to save buyercontact
in buyercontact
table. When I try to add BuyerContact
table in the edmx file, Visual Studio 2010 won't allow me to do that.
How do I save information in buyercontact
table? Please help.
They say if appropriate relationship is maintained in the database/edmx, buyercontact will be saved to database as well when i cave "contact". I search through the internet, i also found similar questions asked but i could not understand.
Please help. do i have to write some special code to save BuyerContact
When I write this code to save contact along with buyercontact
, I get error
Cannot insert duplicate key in dbo.Buyer
Contact objContact = new Contact();
objContact.FirstName = firstName;
objContact.MiddleName = middleName;
objContact.Lastname = lastName;
objContact.CreatedDate = DateTime.Now;
objContact.AddressId = gAddressId;
var buyer = _buyerRepository.GetSingle(x => x.BuyerId == BuyerID);
objContact.Buyer = buyer;
_contactRepository.Add(objContact);
_contactRepository.Save()
If I remove objContact.Buyer = buyer;
, then contact information is saved successfully but buyercontact
is not saved. Now my problem is as soon as I have contact associated with the buyer I also need to save it in the BuyerContact
table.
I have already been through post here, but O could not understand. I have used generic Linq-to-SQL repository for common database operations like CRUD.
Please help, thanks
