Question

So I have a column named Timestamp in my database with a default value of GetDate().

Whenever I use Entity Framework to insert a record, Timestamp is null.

Why is this the case?

Answer 1

Try changing type to datetime2. See this article for more information. Also try using Calculated storegeneratedpattern

try changing to datetime2 and then workaround by adding Trigger

  SET NOCOUNT ON;
  UPDATE ASBLAH
  SET YourFieldChangeTime = getdate() 
  WHERE YOURId IN(SELECT AS_ID FROM INSERTED)

If you need to read data back of this date you can do this after context.SaveChanges()

context.Refresh(System.Data.Objects.RefreshMode.StoreWins, p);
