sql

I have a USER table in database. The table has a RegistrationDate column which has a default constraint as GETDATE().

When using LINQ, I don't provide any data for RegistrationDate column to make it default. But SQL Server raises error. I think LINQ tries to insert NULL into the column.

How can I make LINQ not to try to insert in the column RegistrationDate, because it has default value?

In other words LINQ to SQL isn’t smart about many to many mappings… >>> More
