与日期值的情况一样，MySQL 也允许我们使用宽松的时间格式。我们可以在时间部分之间使用任何标点符号作为分隔符。一些示例如下 -
mysql> Select timestamp('2017-10-20 04+05+36');
+----------------------------------+
| timestamp('2017-10-20 04+05+36') |
+----------------------------------+
| 2017-10-20 04:05:36 |
+----------------------------------+
1 row in set (0.00 sec)
mysql> Select timestamp('2017-10-20 04*05*36');
+----------------------------------+
| timestamp('2017-10-20 04*05*36') |
+----------------------------------+
| 2017-10-20 04:05:36 |
+----------------------------------+
1 row in set (0.00 sec)
mysql> Select timestamp('2017-10&20 04@05+36');
+----------------------------------+
| timestamp('2017-10&20 04@05+36') |
+----------------------------------+
| 2017-10-20 04:05:36 |
+----------------------------------+
1 row in set (0.00 sec)
mysql> Select timestamp('2017*10@20 04*05*36');
+----------------------------------+
| timestamp('2017*10@20 04*05*36') |
+----------------------------------+
| 2017-10-20 04:05:36 |
+----------------------------------+
1 row in set (0.00 sec)
