我有这张桌子
>每行总计每个“移动物品”
>如果Sum达到我想要的金额,停止查询
>我的期望金额从MAX’Summed Total'(26)开始,并减去我想要的金额(16) @H_502_4@像这样
我只会在数据库中获取这些值.
任何人都可以帮助我做出Oracle DB的sql语句,这将打印我所需的表？

解决方法
基于OP的澄清,通过对问题的评论,可以使用SUM()分析函数来获取运行总数,然后根据条件进行过滤.
@H_502_4@表：
sql> SELECT * FROM t; ID_PRIM ID DT MOVED ---------- ----- --------- ---------- 1003 12_1 01-NOV-13 2 1003 12_2 01-OCT-13 3 1003 12_3 01-DEC-14 5 1003 12_4 01-FEB-15 10 1003 12_5 01-APR-12 1 1003 12_11 01-JAN-11 5 6 rows selected. sql>@H_502_4@运行总计

sql> WITH DATA AS 2 ( SELECT t.*,SUM(moved) OVER(ORDER BY dt) sm FROM t ORDER BY dt DESC 3 ) 4 SELECT * FROM DATA t WHERE sm > 5 (SELECT MAX(sm) FROM data 6 ) - 16 ; ID_PRIM ID DT MOVED SM ---------- ----- --------- ---------- ---------- 1003 12_4 01-FEB-15 10 26 1003 12_3 01-DEC-14 5 16 1003 12_1 01-NOV-13 2 11 sql>@H_502_4@在更新的查询中,MAX(sm)返回26,然后在条件WHERE sm> MAX(sm)-16表示返回“sm”值大于26 -16即10的所有行.您可以使用替换变量在运行时输入值16.
