sql分组查询完整句子

发布时间: 2022-05-01 17:49:24

sql语句分组查询

select case_id,
Month||'月份',
sum(jqjb_id)
from (
select case_id,
to_char(recDate,'MM') Month,
jqjb_id
from table_name
)
group by case_id,
Month||'月份'

如果以上字段是实际字段,那么把 table_name修改成实际表明即可完成查询

❷ 求救SQL分组查询统计查询语句

select statues as type ,count(*) as number from FeedbackResults
group by statues order by id asc

statues as type :查询状态,用type表示;
count(*) as number:查询对应状态的数目,用number表示;
group by statues :按状态分组查询;
order by id asc:按状态id升序排列。

❸ 求SQL大神给写一个分组查询语句

select 公司编号,部门编号,
max(case when substring(部门分组编号,1,1)='A' then 部门分组编号 else '-' end) 部门分组A,
max(case when substring(部门分组编号,1,1)='B' then 部门分组编号 else '-' end) 部门分组B,
max(case when substring(部门分组编号,1,1)='C' then 部门分组编号 else '-' end) 部门分组C,
max(case when substring(部门分组编号,1,1)='D' then 部门分组编号 else '-' end) 部门分组D
from table group by 公司编号,部门编号

❹ 求几个简单的SQL单表分组查询语句

如果最高分不只一个呢.....

select * from Result where grade=1 and gender='男' and score = (select max(score) from result);

select * from Result where grade=1 and score=(select max(score) from Result);

select * from Result where gender='女'and score=(select max(score) from Result);

select * from Result where score in (select max(score) from Result group by grade);
注:
grade 年级
name 姓名
gender 性别
score 分数
谁用谁知道!

❺ sql分组查询语句

只是查询出来么?
select store_no 商品,in_code 识别码,quantity 数量,store_no 仓库,supplier_no 供货商 from (表明) where in_date=‘指定的日期’
(⊙﹏⊙)b,你的商品,仓库,供货商应该都是关联了字典表的

❻ sql 分组查询语句

这个很简单啊,就是四个表之间串一下,上sql
select A.NAME 影片名,B.RUNTIME 放映时间,C.TIME 订单时间,C.NUM 顾客编号
from FILM A,RUN B,ORDER C,RESERVATIONS D
WHERE D.TIME=C.TIME AND D.FMN=A.FMN AND A.FMN=B.FMN
试试吧

❼ sql多条件分组查询,求sql语句。

分组是用来聚集汇总的,如求平均、求总和、求最大等
你这个不需要分组,直接排序就可以了

selectname,datefromtableorderbynameasc,datedesc

如果每组要按date的降序排列,也挺简单

with t1 as (select name, max(date) md from table group by name,

t2 as (select table.name name, table.date date, t1.md from table join t1 on table.name=t1.name

order by t1.md)

select name,date from t2

❽ SQL语句待条件分组查询

--查所有的 就是重复的
select CHI,count(aid) aid from tb where CHI in ('z','w','v') group by CHI
--不重复的
select CHI,count(distinct aid) aid from tb where CHI in ('z','w','v') group by CHI

❾ 请使用你熟悉的一种数据库,用SQL语句写出分组查询语句

有一张表如下:
create table topic
(
Topicid int,
title nvarchar(10),
boardid int,
addtime datetime
)
内容如下:
insert topic select
1, 'abc', 100, '2007-1-1'
union all select 2, 'era', 101, '2007-1-2'
union all select 3, 'avx', 102, '2007-1-3'
union all select 4, 'zcv', 100, '2007-1-4'
union all select 5, 'jhv', 100, '2007-1-5'
union all select 6, 'ztw', 103, '2007-1-6'
union all select 7, 'xcv', 102, '2007-1-7'
union all select 8, 'zww', 104, '2007-1-8'
union all select 9, 'zqw', 105, '2007-1-9'
union all select 10, 'zti', 103, '2007-1-10'
要求:按照boardid分组,按照datetime排序,取出前五条
语句:
select top 5 boardid from
(
select boardid,max(addtime) as addtime
from topic
group by boardid
) tmp order by addtime desc

解释:
1,group by 和 order by 不能同时使用,所以当要分组后再排序的时候就要嵌套(先分好组再排序)
2,但是在group by的时候,你要查询的字段必须是你分组的字段,如果group by 两个字段,分组时是按照两个字段同时相等的分组,因此达不到自己想要的结果.
但是使用一个字段分组,要查到两个字段就得:
select boardid,max(addtime) as addtime
from topic
group by boardid

❿ sql分组查询的完整语句

分组查询 group by 主要是对(count,sum,avg,min,max)
例如
表A
a b c
一 1 2
一 1 3
二 2 5
三 7 7
二 9 9
select a,sum(b),sum(c) from A group by a
对分组数据进行限制
select a,sum(b),sum(c) from A group by a having sum(b)>5
