我的查询有问题。我有一张桌子。表中的值是不同的，我在每行中呈现相同的值（10）以简化和更好地理解问题
| ID | UniqueProcutId | Year | Month | Value |
-----|----------------|------|-------|-------|
| 1 | wwee124 | 2015 | 1 | 10 |
| 2 | wwee124 | 2015 | 2 | 10 |
| 3 | wwee124 | 2015 | 3 | 10 |
| 4 | wwee124 | 2015 | 4 | 10 |
| 5 | wwee124 | 2015 | 5 | 10 |
| 6 | wwee124 | 2015 | 6 | 10 |
| 7 | wwee124 | 2015 | 7 | 10 |
| 8 | wwee124 | 2015 | 8 | 10 |
| 9 | wwee124 | 2015 | 9 | 10 |
| 10 | wwee124 | 2015 | 10 | 10 |
| 11 | wwee124 | 2015 | 11 | 10 |
| 12 | wwee124 | 2015 | 12 | 10 |
| 13 | wwee124 | 2016 | 1 | 10 |
| 14 | wwee124 | 2016 | 2 | 10 |
| 15 | wwee124 | 2016 | 3 | 10 |
我想要实现的是查询将返回一年中每个月的累积值。我的意思是：
SELECT ID, PRODUCTID, YEAR, MONTH,
SUM(VALUE) OVER(?????)
我无法处理它:( 查询应返回：
| ID | UniqueProcutId | Year | Month | Value |
-----|----------------|------|-------|-------|
| 1 | wwee124 | 2015 | 1 | 10 |
| 2 | wwee124 | 2015 | 2 | 20 |
| 3 | wwee124 | 2015 | 3 | 30 |
| 4 | wwee124 | 2015 | 4 | 40 |
| 5 | wwee124 | 2015 | 5 | 50 |
| 6 | wwee124 | 2015 | 6 | 60 |
| 7 | wwee124 | 2015 | 7 | 70 |
| 8 | wwee124 | 2015 | 8 | 80 |
| 9 | wwee124 | 2015 | 9 | 90 |
| 10 | wwee124 | 2015 | 10 | 100 |
| 11 | wwee124 | 2015 | 11 | 110 |
| 12 | wwee124 | 2015 | 12 | 120 |
| 13 | wwee124 | 2016 | 1 | 10 |
