mySQL:将“yyyy ddThh-ss.ss.sssz”转换为“yyyy dd hh-mm-ss”。

Question

我想用mySQL将我的数据从“yyy-mm-ddthh-ss.sssz”转换为“”。

我试过用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                                     |
+---------------------------------------------------------+

对演员来说：

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                                                       |
+---------------------------------------------------------------------------+

但每次我收到警告：

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

在没有警告的情况下，我怎么能得到2014-09-29 14:00:00？

Answer 1

我终于找到了！

str-to-date

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                                |
+----------------------------------------------------+
1 row in set (0.00 sec)

Answer 2

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