Who says it cannot be created. I just created 1 in MySQL.
mysql> create table DUMMY_TABLE(id INT NOT NULL, first_name VARCHAR(20) default NULL, last_name VARCHAR(20) default NULL, salary INT default NULL);
Query OK, 0 rows affected (0.12 sec)
mysql> desc DUMMY_TABLE;
+------------+-------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+------------+-------------+------+-----+---------+-------+
| id | int(11) | NO | | NULL | |
| first_name | varchar(20) | YES | | NULL | |
| last_name | varchar(20) | YES | | NULL | |
| salary | int(11) | YES | | NULL | |
+------------+-------------+------+-----+---------+-------+
4 rows in set (0.00 sec)
