Hello All,
During an interview I was asked "why comment is considered as a DDL statement though it does not change structure of an object".
My reply was though it does not directly changes structure of an object [table, column, view etc], however it provides information about it.
Also comment adds data in data dictionary table.
But interviewer was not satisfied with my answer.
I tried searching answer on web, but could not find much details.
Could anybody please suggest something on this.
