How do we drop a multi-column UNIQUE index?

mysql> DROP index id_fname_lname on employee; Query OK, 0 rows affected (0.30 sec) Records: 0 Duplicates: 0 Warnings: 0

mysql> show index from employee; Empty set (0.00 sec) mysql> describe employee; +------------+-------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +------------+-------------+------+-----+---------+-------+ | empid | int(11) | YES | | NULL | | | first_name | varchar(20) | YES | | NULL | | | last_name | varchar(20) | YES | | NULL | | +------------+-------------+------+-----+---------+-------+ 3 rows in set (0.08 sec)
