Erweiterung aus einer Liste von Vollbereichen zwischen zwei Feldern

Question

Ich versuche, ein Skript zu schreiben, die zwei verschiedene Felder nimmt und listet heraus, was die Werte zwischen ihnen wären Ie

ID|Start#|End# 
1 |1  |5 
2 |6  |8 
3 |9  |10 

als

Anzeige würde

ID |FullRange 
1 |1 
1 |2 
1 |3 
1 |4 
1 |5 
2 |6 
2 |7 
2 |8 
3 |9 
3 |10 

Answer 1

können Sie rekursive, dies zu tun.

WITH cte ([ID], [END#], FullRange) 
AS 
(
-- Anchor member definition 
SELECT ee.[ID] 
,ee.[END#] 
,ee.[START#] as FullRange 
FROM [master].[dbo].[test] ee 
where ee.[START#] < ee.[END#] 
UNION ALL 

-- Recursive member definition 
SELECT e.[ID] 
,e.[END#] 
,FullRange +1 
FROM [master].[dbo].[test] e inner join cte 
on e.id = cte.id and FullRange +1 <= cte.END# 
) 
-- Statement that executes the CTE 
SELECT ID,FullRange 
FROM cte 
ORDER BY ID 

Ergebnis ist wie folgt:

ID FullRange 
1 1 
1 2 
1 3 
1 4 
1 5 
2 6 
2 7 
2 8 
3 9 
3 10 

Answer 2

können Sie eine Tally Table verwenden Zahl von [Start#] zu [End#] generieren:

WITH E1(N) AS(-- 10^1 = 10 rows 
    SELECT 1 FROM(VALUES (1),(1),(1),(1),(1),(1),(1),(1),(1),(1))t(N) 
), 
E2(N) AS(SELECT 1 FROM E1 a CROSS JOIN E1 b), -- 10^2 = 100 rows 
E4(N) AS(SELECT 1 FROM E2 a CROSS JOIN E2 b), -- 10^4 = 10,000 rows 
CteTally(N) AS(
    SELECT TOP(SELECT MAX([End#] - [Start#]) + 1 FROM Tbl) 
     ROW_NUMBER() OVER(ORDER BY(SELECT NULL)) - 1 
    FROM E4 
) 
SELECT 
    t.ID, 
    FullRange = t.[Start#] + ct.N 
FROM Tbl t 
CROSS JOIN CteTally ct 
WHERE t.[Start#] + ct.N <= t.[End#] 
ORDER BY t.ID, FullRange

Answer 3

declare @tbl table (id int, start int, [end] int) 
insert @tbl values (1, 1, 5), (2, 6, 8), (3, 9 , 10); 


;with t(c) as 
(
    select * from (values (0), (1), (2), (3), (4), (5), (6), (7), (8), (9)) a(b) 
), 
x(y) as 
(
    select t1.c * 100 + t2.c * 10 + t3.c 
    from t t1 
    cross join t t2 
    cross join t t3 
) 
select t.id, x.y 
from x 
join @tbl t on t.start <= x.y and t.[end] >= x.y 
order by t.id, x.y
