How to fix this function?

ERROR 1292 (22007): Truncated incorrect datetime value: '10/29/2015 2:12 PM'

CodePudding user response：

You have "PM" in your string without giving it a format code for it.

mysql> select STR_TO_DATE('10/29/2015 2:12 PM','%m/%d/%Y %h:%i') as d;
 --------------------- 
| d                   |
 --------------------- 
| 2015-10-29 02:12:00 |
 --------------------- 
1 row in set, 1 warning (0.00 sec)

mysql> show warnings;
 --------- ------ ---------------------------------------------------------- 
| Level   | Code | Message                                                  |

Use %p for the "AM"/"PM" part:

mysql> select STR_TO_DATE('10/29/2015 2:12 PM','%m/%d/%Y %h:%i %p');
 ------------------------------------------------------- 
| STR_TO_DATE('10/29/2015 2:12 PM','%m/%d/%Y %h:%i %p') |
 ------------------------------------------------------- 
| 2015-10-29 14:12:00                                   |
 ------------------------------------------------------- 
1 row in set (0.00 sec)

(No warning when you do this.)
