结果：
Xiaoyuan245437 大大说：
你所说的结果当中可以也包括 人事部呢 ？ 人事部 网站 财务 应该都属于 万蓝科技对把？
查询结果在图片上了，您说的是对的
为了符合原来每个月工资消费的需求我特意改了下
sql如下
--修改OrgID，ParentID，OrgID总消费的视图 alter VIEW [dbo].[ViewSumOrgID] AS SELECT ISNULL(SUM(dbo.Budget.Cost), 0) AS csum, dbo.Org.OrgID, dbo.Org.ParentID,MONTH(dbo.Budget.AddDate) as cM FROM dbo.Budget RIGHT OUTER JOIN dbo.Org ON dbo.Budget.OrgID = dbo.Org.OrgID GROUP BY dbo.Org.OrgID, dbo.Org.ParentID,MONTH(dbo.Budget.AddDate) GO WITH stb([id],ssum,sParentID,sM) AS( SELECT OrgID,csum,ParentID,cM FROM [ViewSumOrgID] WHERE OrgID in (select * from f_levelid()) UNION ALL SELECT A.OrgID,B.ssum+A.csum,A.ParentID,B.sM FROM [ViewSumOrgID] A,stb B WHERE A.OrgID=B.sParentID ) select * from ( select SUM(ssum) tsum,id,sM as 月份 from stb group by stb.id,sM) t ,Org where t.id = Org.OrgID
