我有一个表叫 LocationProduct 其结构如下：
+--------------+-------------+-----------+
| FkLocationId | FkProductId | SortValue |
+--------------+-------------+-----------+
| 1 | 100 | 1 |
+--------------+-------------+-----------+
| 1 | 101 | 2 |
+--------------+-------------+-----------+
| 1 | 102 | 3 |
+--------------+-------------+-----------+
| 1 | 103 | 4 |
+--------------+-------------+-----------+
| 1 | 104 | 5 |
+--------------+-------------+-----------+
| 1 | 105 | 6 |
+--------------+-------------+-----------+
| 2 | 100 | 1 |
+--------------+-------------+-----------+
| 2 | 101 | 2 |
+--------------+-------------+-----------+
| 2 | 102 | 3 |
+--------------+-------------+-----------+
| 2 | 103 | 4 |
+--------------+-------------+-----------+
| 2 | 104 | 5 |
+--------------+-------------+-----------+
| 2 | 105 | 6 |
+--------------+-------------+-----------+
现在我需要增加 SortValue 当我插入一条新的记录时，将列的值增加一个。举个例子：
INSERT INTO BranchServices(FkBranchId,FkServiceId,SortValue)
VALUES(1,106,1)
我需要更新 FkLocationId = 1 相关的SortValue逐一输入，我需要如下的输出。
+--------------+-------------+-----------+
| FkLocationId | FkProductId | SortValue |
+--------------+-------------+-----------+
| 1 | 100 | 2 |
+--------------+-------------+-----------+
| 1 | 101 | 3 |
+--------------+-------------+-----------+
| 1 | 102 | 4 |
+--------------+-------------+-----------+
| 1 | 103 | 5 |
+--------------+-------------+-----------+
| 1 | 104 | 6 |
+--------------+-------------+-----------+
| 1 | 105 | 7 |
+--------------+-------------+-----------+
| 1 | 106 | 1 |
+--------------+-------------+-----------+
在这里你可以看到我更新了每个旧记录的SortValue。我怎样才能做到这一点？
