ID Column:

  • ID Column is a field which is used in databases having two or more themes and is divided according to the respective themes.
  • It is to provide uniqueness and avoid duplicity in the database and is quite similar to primary key but it differs from primary key as it is managed by the server and has the property of auto-incrementing which cannot be modified.
