Ⅰ sql如何对分组后运算出来的结果进行排序
提供两种方案，第一种是降序
select sno,avg(grade) 'nihao' from sc
group by sno order by 'nihao' desc
第二种是升序
select sno,avg(grade) 'nihao' from sc
group by sno order by 'nihao' asc
其中‘nihao’表示avg(grade)这个列的别名
Ⅱ sql分组之后怎么排序
group by的功能是将相同条件的结果值显示为一行，如果全显示出来只说明以为问题，你查询的内容是不同的
像两行，由于RecruitmentInformationID
值是不同的，所以不会被归为同一组，一般UUID都是唯一值，如果你使用uuid作为你的RecruitmentInformationID
，那么你的表中实际上不会存在重复数据，如果查询内容包含RecruitmentInformationID
，group by就变得没意义了
Ⅲ sql 分组排序 高手进啊！！
不都一样吗？那就把week改成date你试试
select * from b order by week desc,clickcount desc
Ⅳ SQL分组排序
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 如何分组排序同时进行
1、首先输入代码：
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、然后再输入代码：
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 --指的是内表
and Gender='女' --指的是外表
order by Classid, English desc
Ⅵ sql 分组后排序
select*,ROW_NUMBER()over(partitionby品牌orderby市场份额desc)as排名FROM市场份额表
Ⅶ sql 分组排序
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先分组后排序的问题
selectregtime,ccount,row_number()over(partitionbycasewhenccount=0then0else1endorderbyregtime)from表
Ⅸ sql语句 在分组内排序
只能用存储过程
思路如下
将分组那个字段比如是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 分组统计并排序
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
要想区别并列现象还要复杂一些，可能简单的语句解决不了
