我有一个带有日期戳的交易表。我想添加一列来对记录进行编号,但是他们必须每天重新启动。这可能吗?
示例:
+------------------+--------------+
| Date | Data |
+------------------+--------------+
| 19-10-2017 10:18 | Transaction1 |
| 19-10-2017 12:18 | Transaction2 |
| 19-10-2017 13:23 | Transaction3 |
| 20-10-2017 11:18 | Transaction4 |
| 20-10-2017 14:18 | Transaction5 |
| 21-10-2017 09:18 | Transaction6 |
| 21-10-2017 10:18 | Transaction7 |
| 21-10-2017 11:18 | Transaction8 |
| 21-10-2017 12:18 | Transaction9 |
+------------------+---------+----+
我想要这个:
+------+------------------+--------------+
| Nr | Date | Data |
+------+------------------+--------------+
| 1 | 19-10-2017 10:18 | Transaction1 |
| 2 | 19-10-2017 12:18 | Transaction2 |
| 3 | 19-10-2017 13:23 | Transaction3 |
| 1 | 20-10-2017 11:18 | Transaction4 |
| 2 | 20-10-2017 14:18 | Transaction5 |
| 1 | 21-10-2017 09:18 | Transaction6 |
| 2 | 21-10-2017 10:18 | Transaction7 |
| 3 | 21-10-2017 11:18 | Transaction8 |
| 4 | 21-10-2017 12:18 | Transaction9 |
