MySQL：將“ yyyy-mm-ddThh-mm-ss.sssZ”轉換為“ yyyy-mm-dd hh-mm-ss”

Question

我想使用mySQL將數據從“ yyyy-mm-ddThh-mm-ss.sssZ”轉換為“ yyyy-mm-dd hh-mm-ss”。

我嘗試了convert_tz：

mysql> SELECT CONVERT_TZ('2014-09-29T14:00:00.99Z','+00:00','+00:00');
+---------------------------------------------------------+
| convert_tz('2014-09-29T14:00:00.99Z','+00:00','+00:00') |
+---------------------------------------------------------+
| 2014-09-29 14:00:00                                     |
+---------------------------------------------------------+

並與演員：

mysql> SELECT CONVERT_TZ(CAST('2014-09-29T14:00:00.99Z' 
       AS datetime),'+00:00','+00:00');
+---------------------------------------------------------------------------+
| CONVERT_TZ(CAST('2014-09-29T14:00:00.99Z' AS datetime),'+00:00','+00:00') |
+---------------------------------------------------------------------------+
| 2014-09-29 14:00:00                                                       |
+---------------------------------------------------------------------------+

但是每次我收到警告時：

mysql> show warnings;
Level   | Code | Message
Warning | 1292 | Truncated incorrect datetime value: '2014-09-29T14:00:00.99Z'

我如何獲得2014-09-29 14:00:00但沒有警告？

mysql> SELECT STR_TO_DATE('2015-08-07T09:27:54Z','%Y-%m-%dT%TZ');
+----------------------------------------------------+
| STR_TO_DATE('2015-08-07T09:27:54Z','%Y-%m-%dT%TZ') |
+----------------------------------------------------+
| 2015-08-07 09:27:54                                |
+----------------------------------------------------+

請嘗試SELECT DATE_FORMAT('2014-09-29T14:00:00.99Z', '%Y-%m-%d %T');
