查询一个表里面某一分段里面有多少人表1
sno score
1 150
2 133
3 123
4 80
5 90
6 60
7 34
8 21
9 102
表2
sno score
11 12
22 105
33 76
42 98
53 88
63 78
72 77
82 111
92 132
查询score在150,145-140,140-135.......5-0分数段的人，
如果将此分数间隔变成10，20又该怎么查？
sql
------解决方案--------------------
select score/5 as fs,count(*) fc
from t
group by score/5
------解决方案--------------------
查询结果可以保存为多种格式的文件的
也可以全选，复制粘贴到excel

没明白，表1表2啥关系，比如：90属于80到90直接还是90到100之间呢
不明白，不明白，是不是你想要的。。。DECLARE @SpaceScore INT=10 --分数间隔
DECLARE @EndScore INT=150
IF OBJECT_ID('tempdb..#ScoreOut','U') IS NOT NULL DROP TABLE #ScoreOut
CREATE TABLE #ScoreOut
(
Id INT IDENTITY(1,1)
,StartScore INT
,EndScore INT
)
;WITH CTE(Score)
AS (
SELECT 0 AS Score
UNION ALL
SELECT Score+@SpaceScore
FROM CTE
WHERE Score<@EndScore-@SpaceScore
)
INSERT INTO #ScoreOut(StartScore,EndScore)
SELECT Score,Score+@SpaceScore
FROM CTE
IF OBJECT_ID('tempdb..#Score','U') IS NOT NULL DROP TABLE #Score
CREATE TABLE #Score
(
sno INT
,Score INT
)
INSERT INTO #Score
SELECT 1, 150
UNION ALL SELECT 2, 133
UNION ALL SELECT 3, 123
UNION ALL SELECT 4, 80
UNION ALL SELECT 5, 90
UNION ALL SELECT 6, 60
UNION ALL SELECT 7, 34
UNION ALL SELECT 8, 21
UNION ALL SELECT 9, 102
SELECT CAST(B.StartScore AS VARCHAR)+'-'+CAST(B.EndScore AS VARCHAR) AS ScoreSpace
,COUNT(*) AS Cnt
FROM #Score AS A
JOIN #ScoreOut AS B ON A.Score BETWEEN B.StartScore AND B.EndScore
GROUP BY CAST(B.StartScore AS VARCHAR)+'-'+CAST(B.EndScore AS VARCHAR)
/*
ScoreSpace Cnt
100-110 1
120-130 1
130-140 1
140-150 1
20-30 1
30-40 1
50-60 1
60-70 1
70-80 1
80-90 2
90-100 1
*/

试试：
if object_id('s') is not null
drop table s
go
create table s(id int,score int)
INSERT INTO s
SELECT 1, 150
UNION ALL SELECT 2, 133
UNION ALL SELECT 3, 123
UNION ALL SELECT 4, 80
UNION ALL SELECT 5, 90
UNION ALL SELECT 6, 60
UNION ALL SELECT 7, 34
UNION ALL SELECT 8, 21
UNION ALL SELECT 9, 102
go
declare @table_name nvarchar(100);
declare @sql nvarchar(max);
declare @start int;
declare @end int;
declare @interval int;
select @start = 0, --开始的分数
@end = 150, --结束的分数
@interval = 10,--间隔
@sql = '',
@table_name = 's'; --这里的表的名称是s
;with t
as
(
select @start as start_score,@start + @interval as end_score
union all
select start_score + @interval,
case when end_score + @interval > @end
then @end
else end_score + @interval
end
from t
where start_score + @interval < @end
),
tt
as
(
select start_score,
end_score,
cast(end_score as varchar) +'-'+cast(start_score as varchar) as score_range
from t
)
select @sql = @sql +
',count(case when score >'+cast(start_score as varchar) +
' and score <= '+cast(end_score as varchar) +
