In MySQL, you can use the ALTER TABLE statement to add comments to a field. Here are the specific steps:

  1. Open the MySQL command line or MySQL client, and connect to the desired database.
  2. Change the structure of the table
  3. Change the column type of the specified column in the given table and add a comment.
  4. name of the table
  5. name of the column
  6. type of column
  7. response
  8. people
  9. user handle
  10. Change the data type of the column “username” in the table “users” to varchar(50) and add a comment ‘用户名’.
  11. Once the above statement is executed, the field’s description will be added to the database.

Furthermore, visual tools such as Navicat or phpMyAdmin can be used to interact with the database, which generally provide intuitive interfaces for adding field comments.
