ROUND((SUM(CASE WHEN EXTRACT(YEAR FROM SB.SKSSQQ) = '2022' THEN YBNSE.YNSR END) OVER() - SUM(CASE WHEN EXTRACT(YEAR FROM SB.SKSSQQ) = '2021' THEN YBNSR.YNSE END) OVER()) / SUM(CASE WHEN EXTRACT(YEAR FROM SB.SKSSQQ) = '2021' THEN YBNSR.YNSE END) OVER() * 100, 2) YNSEBDL 请模拟一下这段代码

假设有如下数据：

| SB.SKSSQQ | YBNSE.YNSR | YBNSR.YNSE |
|-----------|------------|------------|
| 2021-01-01 | 100 | 100 |
| 2021-02-01 | 200 | 300 |
| 2022-01-01 | 150 | 200 |

则运行这段代码的结果为：

ROUND((SUM(CASE WHEN EXTRACT(YEAR FROM SB.SKSSQQ) = '2022' THEN  YBNSE.YNSR END) OVER() - SUM(CASE WHEN EXTRACT(YEAR FROM SB.SKSSQQ) = '2021' THEN YBNSR.YNSE END) OVER()) / SUM(CASE  WHEN EXTRACT(YEAR FROM SB.SKSSQQ) = '2021' THEN YBNSR.YNSE  END) OVER() * 100, 2) YNSEBDL

= ROUND((150 - 400) / 400 * 100, 2)

= ROUND(-62.5, 2)

= -62.5

因此，假设有以上数据，这段代码的运行结果为-62.5。
