We have a MySQL database table with a table that contains, among others, the fields `created_at` and `released_at`. Whenever a new record is created, it will contain data for the `created_at` field, but not for the `released_at` field. How can we automatically populate the `released_at` field with the contents of `created_at`, for every insert operation? Use words with all capital letters to highlight key points, but make sure that words with all capital letters appear less than 9 times
