mysql str_to_date 잘못된 datetime 값 문제

Question

mysql이 내 datetime 값을 사용하지 않는 이유는 무엇입니까?

mysql> select STR_TO_DATE('2017-10-06T00:00:00', '%%Y-%%m-%%dT%%H:%%i:%%s'); 
+---------------------------------------------------------------+ 
| STR_TO_DATE('2017-10-06T00:00:00', '%%Y-%%m-%%dT%%H:%%i:%%s') | 
+---------------------------------------------------------------+ 
| NULL               | 
+---------------------------------------------------------------+ 
1 row in set, 2 warnings (0.00 sec) 

mysql> show warnings 
    -> ; 
+---------+------+--------------------------------------------------------------------------+

시도 :

    '2017-10-06T00:00:00', 
    '%Y-%m-%dT%H:%i:%s' 
);
