db2实现每条数据累加

最近遇到一个需求，需要实现当年每个月数据累加

SELECT   XALISEDATA xAliseData, SERIESDATA seriesData
FROM     (SELECT   SERIESDATA,
XALISEDATA,
ROW_NUMBER() OVER(ORDER BY XALISEDATA) RK
FROM     (
SELECT CASE WHEN double(IMPORTED_MONTH)=0.0 THEN 0 ELSE double(IMPORTED_MONTH)/10000 END AS seriesData,TAX_YEAR||TAX_MONTH AS xAliseData from APPINST.HGXX
where 1=1
    AND ENTERPRISE_NAME = '浙江进出口有限公司'
    AND TAX_YEAR = '2018'

order by TAX_YEAR||TAX_MONTH DESC )
) order by XALISEDATA

效果图，如下：

以上仅供参考
