In Code first The INSERT statement conflicted with the FOREIGN KEY constraint

Question

I just started using Code first approach for creating databases. I have following 3 tables :

public partial class AccountHolder
{
    public int AccountHolderId          


        

Answer 1

In your table dbo.AccountHolders and dbo.Nominees, it has a foreign key reference to another table. The way a FK works is it cannot have a value in that column that is not also in the primary key column of the referenced table.

If you have SQL Server Management Studio, open it up and sp_help 'dbo.dbo.Nominees'. See which column that FK is on, and which column of which table it references. You're inserting some bad data.Do the same for sp_help 'dbo.dbo.AccountHolders '.

Hope this helps.

Answer 2

You try to insert Address Nominees_NomineeId that is not exists in Nominee.You should First instance of Nominee then fill value and create Address and fill value last create instance of AccountHolder.and then save
