Bagaimana untuk menambah komen dalam kod MySQL?

mysql> create table CommentDemo
   -> (
   -> id int   #Id is an integer type
   -> );
Query OK, 0 rows affected (0.65 sec

#Id is an integer type

mysql> create table CommentDemo2
   -> (
   -> id int -- id is an integer type
   -> );
Query OK, 0 rows affected (0.49 sec)

- id is an integer type

mysql> create table CommentDemo3
   -> (
   -> /*id is an integer type */
   -> id int
   -> );
Query OK, 0 rows affected (0.52 sec)

/*id is an integer type */
