Question

我有一张看起来像这样的表：

+--------------+------------+--------+
|     Acno     | ValueDate  | Amount |
+--------------+------------+--------+
| 190010283045 | 20/01/2015 |  -3000 |
| 190010283045 | 20/01/2015 |   3000 |
| 190010283045 | 20/01/2015 |  -3000 |
| 190010283118 | 08/01/2015 |    100 |
| 190010283118 | 08/01/2015 |    100 |
| 190010283266 | 19/01/2015 |  -3500 |
| 190010283266 | 19/01/2015 |   3500 |
| 190010283533 | 14/01/2015 |  -5000 |
| 190010283533 | 16/01/2015 |   5000 |
+--------------+------------+--------+

要求是比较表中的两个连续行：

如果Acno相同，
然后如果ValueDate相同
然后，如果两行中金额的总和是= 0
然后两行都应标记为1

标记的行不应再次用于比较。

因此，上表所需的报告将是：

+--------------+------------+--------+------+
|     Acno     | ValueDate  | Amount | Flag |
+--------------+------------+--------+------+
| 190010283045 | 20/01/2015 |  -3000 |    1 |
| 190010283045 | 20/01/2015 |   3000 |    1 |
| 190010283045 | 20/01/2015 |  -3000 |      |
| 190010283118 | 08/01/2015 |    100 |      |
| 190010283118 | 08/01/2015 |    100 |      |
| 190010283266 | 19/01/2015 |  -3500 |    1 |
| 190010283266 | 19/01/2015 |   3500 |    1 |
| 190010283533 | 14/01/2015 |  -5000 |      |
| 190010283533 | 16/01/2015 |   5000 |      |
| 190010283533 | 27/01/2015 |  -5000 |      |
+--------------+------------+--------+------+
