Hello,
I have a problem with dblinq when I have a left join with null value.
My example is simple, I have a table PERSON associated with ADDRESS
but this adress may be null.
I generated my DataContext with DBMETAL.EXE, but when I execute my
request linq an error message appears : An object which allows the
null value must have a value .
Here's my request :
String connectionString =
System.Configuration.ConfigurationManager.AppSettings
[ConstantCnx.ConnectionString2];
MySqlConnection oConnection = new MySqlConnection(connectionString);
PetStoredB db3 = new PetStoredB(oConnection);
var Customers2 = (from c in db3.TCustomer select new TCustomer() { ID
= c.ID, TAddress = c.TAddress});
foreach (TCustomer customer in Customers2)
{
System.Console.WriteLine(customer.TAddress.City);
}
If it can help you, the problem come from QueryRunner.cs file at var
row = rowObjectCreator(reader,
selectQuery.DataContext._MappingContext);
But I don't know resolve this bug.
Have you an idea ?
Thank you.
Seb.
