試試這個:
DECLARE @Student table (SNO int,Marks int)
INSERT INTO @Student VALUES (1, 0)
INSERT INTO @Student VALUES (1, 3)
INSERT INTO @Student VALUES (1, 45)
INSERT INTO @Student VALUES (1, 95)
INSERT INTO @Student VALUES (1, 85)
INSERT INTO @Student VALUES (1, 97)
INSERT INTO @Student VALUES (1, 92)
DECLARE @StartNumber int
,@EndNumber int
SELECT @StartNumber=0
,@EndNumber=100
;WITH AllNumbers AS
(
SELECT @StartNumber AS Number
UNION ALL
SELECT Number+10
FROM AllNumbers
WHERE Number<@EndNumber
)
SELECT
n.number AS MarksRange,COUNT(s.SNO) AS CountOf
FROM AllNumbers n
LEFT OUTER JOIN @Student s ON s.Marks=n.Number OR (s.Marks>n.Number-10 AND s.Marks<=n.Number)
GROUP BY n.number
OUTPUT:
MarksRange CountOf
----------- -----------
0 1
10 1
20 0
30 0
40 0
50 1
60 0
70 0
80 0
90 1
100 3
,如果你不2005+你需要一個Numbers table更換CTE SQL Server上。並使用如下查詢:
SELECT
n.number,COUNT(s.SNO),0 AS CountOf
FROM Numbers n
LEFT OUTER JOIN @Student s ON s.Marks=n.Number OR (s.Marks>n.Number-10 AND s.Marks<=n.Number)
WHERE n.Number>[email protected] AND n.Number<[email protected] AND CONVERT(decimal(3,1),n.Number/10)=n.Number/10.0
GROUP BY n.number
完美。像冠軍一樣工作。非常感謝。 – Mahesh 2010-09-16 15:07:29
