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.
Trim is one of the most frequently used operation over String data types. A developer often come across a scenario where they have the string with leading and trailing spaces around string. If your business logic suggests that the logs around the spaces are not useful they should be trimmed. However, in SQL Server there is no TRIM function. When a TRIM function is used it will throw an error.
