What should I do when I see the (Invalid value for 'created_at') error message when importing a database? Below is the structure and data of the DB, including the categories, comments, menu, pages, and posts tables.

SET SQL_MODE = "NO_AUTO_VALUE_ON_ZERO";
START TRANSACTION;
SET time_zone = "+00:00";

/*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */;
/*!40101 SET NAMES utf8mb4 */;

To specify the date in a field of a certain type, you can use a trigger for initialization. An example of a trigger is shown below:

CREATE TRIGGER set_date BEFORE INSERT ON categories
 FOR EACH ROW SET NEW.created_at = DATE(NOW())
Note that only DATETIME and TIMESTAMP type fields will automatically be set with the current date and time.
