sql求和语句

发布时间: 2022-01-13 13:56:40

‘壹’ sql按条件汇总求和

如下:

1、第一步,将示例表导入SQL语句中,见下图,转到下面的步骤。

‘贰’ SQL 求和语句

select
sum(*)
from
(SELECT
SUM(zy_detail_charge.charge_amount)
FROM
zy_detail_charge
where
zy_detail_charge.charge_code
in
(select
fee_code
from
or_level
where
or_level
=
'xt'
and
flag
=
'410')
and
data_month
='2010-08'
union
all
SELECT
SUM(mz_charge_detail.quantity)
from
mz_charge_detail
where
mz_charge_detail.charge_item_code
in
(select
fee_code
from
or_level
where
or_level
=
'xt'
and
flag
=
'410'))

‘叁’ sql 求和的语句

select sum(a.a) from
(
SELECT
SUM(zy_detail_charge.charge_amount) FROM zy_detail_charge where
zy_detail_charge.charge_code in (select fee_code from or_level where
or_level = 'xt' and flag = '410')and data_month ='2010-08'
union all
SELECT
SUM(mz_charge_detail.quantity) from mz_charge_detail where
mz_charge_detail.charge_item_code in (select fee_code from or_level
where or_level = 'xt' and flag = '410')and data_month ='2010-08'
) a(a)

‘肆’ 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

(4)sql求和语句扩展阅读:

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〕…〕

‘伍’ sql语句列求和

select sum(数据1),sum(数据2) from table

如果表里只有这两列,则语句如上,如果还有其它列并且需要分组,则添加group by语句,如:
select sum(数据1),sum(数据2) from table
group by 其它列

‘陆’ SQL语句求和查询

select A字段,B字段,C字段,sum(D*E) as 新列,sum(F字段) as F字段,sum(G字段) as G字段 from 表 where H字段>='2015-03-01' and H字段<='2015-03-31' group by A字段,B字段,C字段

‘柒’ SQL里边的求和语句怎么写

用select sum(列名),sum(列名),sum(列名)…… from 表 where 条件。

‘捌’ sql求和这个语句怎么写

select t1.d,(case when t1.a='20190101' then t1.f else 0 end)f,
(case when t1.a='20190102' then t1.f else 0 end)g,
(case when t1.a='20190103' then t1.f else 0 end)h,
from(select a,b,sum(c)as f from table group by a,b)t1

‘玖’ SQL求和表达语句怎么写

Select sum(anzhuang) from client

这就是一个求和语句啊

‘拾’ 求一求和sql语句

如果是学号唯一的:
select min(编号),学号,min(姓名),sum(成绩) as '总成绩' from 成绩表 group by 学号

如果是姓名唯一的:
select min(编号),min(学号),姓名,sum(成绩) as '总成绩' from 成绩表 group by 姓名
