Ⅱ 请问一下，SQL按日期查询，查询每一天之前的金额总和
按天累计么？
select 日期, (select sum(金额) from tb where 日期<t.日期) 日累计金额
from tb t
Ⅲ sql 按天求和
SELECT
日期,
SUM( 数量 ) AS 数量
FROM
表
GROUP BY
日期
Ⅳ sql 按日期排序 求和
求和用sum，排序用order by
若是分别求和 group by 和 sum 配合使用
Ⅳ sql列统计求和
这个方法看起来步骤多 其实蛮简单的。 希望采纳
Ⅵ 如何用SQL统计出第N天及前面每天number的总和
创建测试表及数据
createtabletest
(idint,
numberint)
insertintotestvalues(1,100)
insertintotestvalues(2,150)
insertintotestvalues(3,200)
insertintotestvalues(4,350)
insertintotestvalues(5,150)
insertintotestvalues(6,50)
执行
selectb.id,sum(a.number)fromtesta,testbwherea.id<=b.idgroupbyb.id
结果
Ⅶ SQL多重复数据中取时间最近的一条进行求和，同一张表
你这结果不对吧，carno=1的时间最小的2017/12/21，你写的2017/12/23
selectsum(t.money)
from
(selecta.*froma,
(selectcarno,min(time)timefromagroupbycarno)b
wherea.carno=b.carnoanda.time=b.time)t
基本这样，各种数据库语句差不多都是这个。
Ⅷ sqlserver获取最近六个月天数总和，例如现在是八月份，我要获取2-7月份天数总和
declare
@Interval int, --间隔天数
@BeginDate DateTime, --开始时间
@EndDate DateTime --结束时间
begin
set @BeginDate = DATEADD(day,-DAY(DATEADD(MONTH,-6,GETDATE()))+1,DATEADD(MONTH,-6,GETDATE()))
set @EndDate = EOMONTH(DATEADD(MONTH,-1,GETDATE()))
set @Interval = DATEDIFF(day,@BeginDate,@EndDate)
select @Interval
end
Ⅸ SQL里边的求和语句怎么写
SQL中求和语句分为纵向汇总和横向汇总语句；
假设数据列为：A、B、C、D、E、F、G
纵向汇总语句：
select sum(A),sum(B),sum(C),sum(D),sum(E),sum(F),sum(G) from 表名
横向汇总的SQL语句是：
select A,B,C,D,E,F,G,A+B+C+D+E+F+G from 表名
求所有数据总和的SQL语句是：
select sum(A)+sum(B)+sum(C)+sum(D)+sum(E)+sum(F)+sum(G) from 表名
(9)sql近n天求和扩展阅读：
SQL是一种查询功能很强的语言，只要是数据库存在的数据，总能通过适当的方法将它从数据库中查找出来。SQL中的查询语句只有一个：SELECT，它可与其它语句配合完成所有的查询功能。SELECT语句的完整语法，可以有6个子句。完整的语法如下：
SELECT 目标表的列名或列表达式集合
FROM 基本表或(和)视图集合
〔WHERE条件表达式〕
〔GROUP BY列名集合
〔HAVING组条件表达式〕〕
〔ORDER BY列名〔集合〕…〕
Ⅹ sql如何列统计求和
有个思路：
1、在系统表中找出表名对应的列名，并把每个列名都加上SUM()
select 'sum('+name+'),' from syscolumns
where id=(select id from sysobjects where name='表名')
2、把查询结果复制出来，前面加select 后面加 from 表名。。。。你懂的
注意：复制出来后把最后一个逗号去掉。
3、执行查询
也可以写个存储过程来完成。
