sql分組排序

發布時間: 2022-01-17 08:10:01

sql如何對分組後運算出來的結果進行排序

提供兩種方案,第一種是降序
select sno,avg(grade) 'nihao' from sc
group by sno order by 'nihao' desc
第二種是升序
select sno,avg(grade) 'nihao' from sc
group by sno order by 'nihao' asc

其中『nihao』表示avg(grade)這個列的別名

Ⅱ sql分組之後怎麼排序

group by的功能是將相同條件的結果值顯示為一行,如果全顯示出來只說明以為問題,你查詢的內容是不同的

像兩行,由於RecruitmentInformationID
值是不同的,所以不會被歸為同一組,一般UUID都是唯一值,如果你使用uuid作為你的RecruitmentInformationID
,那麼你的表中實際上不會存在重復數據,如果查詢內容包含RecruitmentInformationID
,group by就變得沒意義了

Ⅲ sql 分組排序 高手進啊!!

不都一樣嗎?那就把week改成date你試試
select * from b order by week desc,clickcount desc

Ⅳ SQL分組排序

create
table
#a
(a
char(10),b
int)
insert
#a
select
'a',1
insert
#a
select
'a',5
insert
#a
select
'b',1
insert
#a
select
'b',4
insert
#a
select
'b',3
insert
#a
select
'b',5
create
table
#c
(id
int
identity(1,1),
a
varchar(10))
insert
into
#c
select
distinct
a
from
#A
create
table
#d
(id
int
,
a
varchar(10),b
int)
declare
@a
int
declare
@b
int
select
@a=min(id)
from
#c
select
@b=max(id)
from
#c
while
(@a<=@b)
begin
select
identity(int,1,1)
as
id
,
t1.a,t1.b
into
#b
from
#a
t1,
#c
t2
where
t1.a=t2.a
and
t2.[id]=@a
order
by
t1.b
insert
into
#d
select
*
from
#b
drop
table
#b
set
@a=@a+1
end
select
*
from
#d

Ⅳ sql 如何分組排序同時進行

1、首先輸入代碼:

SELECT * FROM (select * from CJ where Gender='女') m

where( select COUNT(*) from (select * from CJ where Gender='女') n

where m.Classid = n.Classid and n.English > m.English)<2

order by Classid, English desc

2、然後再輸入代碼:

SELECT * FROM CJ m

where(

select COUNT(*) from CJ n

where m.Classid = n.Classid and n.English > m.English and n.Gender='女')<2 --指的是內表

and Gender='女' --指的是外表

order by Classid, English desc

Ⅵ sql 分組後排序

select*,ROW_NUMBER()over(partitionby品牌orderby市場份額desc)as排名FROM市場份額表

Ⅶ sql 分組排序

with
ranked
as
(select
t1.*,
rank()
over
(partition
by
name
order
by
price
desc)
as
rk
from
table1
t1
join
table2
t2
on
t1.goods=t2.goods)
select
a.name,
b.goods
as
goods1,
c.goods
as
goods2,
d.goods
as
goods3
from
(select
name
from
table1
group
by
name)
a
join
(select
name,
goods
from
ranked
where
rk
=1)
b
on
b.name=a.name
join
(select
name,
goods
from
ranked
where
rk
=2)
c
on
c.name=a.name
join
(select
name,
goods
from
ranked
where
rk
=3)
d
on
d.name=a.name
order
by
name

Ⅷ sql先分組後排序的問題

selectregtime,ccount,row_number()over(partitionbycasewhenccount=0then0else1endorderbyregtime)from表

Ⅸ sql語句 在分組內排序

只能用存儲過程
思路如下
將分組那個欄位比如是A
Create temp table tmp_b
foreach
select distinct A into bianlianga from table
insert into tmp_b
select top 2 B from table where A=bianlianga order by B ;
delete from table where A=bianlianga and B in(select * from tmp_b);
end foreach

Ⅹ SQL 分組統計並排序

with tmp as
(select row_number() over(order by count(val)) as rn,val,count(val) as cnum from table1 group by val)
select * from tmp where rn<3
要想區別並列現象還要復雜一些,可能簡單的語句解決不了
