Presenting a technical session is a greatest experience one can have and I enjoy doing the same. While I write this blog post, I am presenting at Great Indian Developer Summit in India. The event is a grand success and I am having a great time at this event. One of the questions which I often receive is how do one can add the column to existing table which will be auto-populated with the current datetime when the original row is inserted. There is indeed a simple solution to achieve this goal. One has to just create table with default value as a current datetime.
