生成两个数字之间的数字范围

Question

我可以使用查询的一些帮助来扩展我正在使用的CSV,但我不知道处理查询的最佳方法.我的数据如下:

ID-Begin | ID-End | Color | Dwelling
-------------------------------------
79000    | 79999  | Red   | Condo
82100    | 82600  | Blue  | House
etc

我需要在起始ID和结束ID之间生成一个范围,然后复制该范围的颜色和居住条目.这是我希望实现的目标:

 ID   |  Color  | Dwelling
------------------------
79000 |  Red    | Condo
79001 |  Red    | Condo
79002 |  Red    | Condo
.....
79999 |  Red    | Condo
82100 |  Blue   | House
82101 |  Blue   | House
.....
82600 |  Blue   | House

我已经看到其他方法允许我生成单个数字范围,但没有任何方法可以从表中的列中提取开始和结束数字.

无论如何帮助非常感谢!!

Answer 1

试试这个:

declare @content table ([ID-Begin] int,[ID-End] int,Color char(20),Dwelling char(20))
insert into @content values(79000,79999,'Red' ,'Condo')
insert into @content values(82100,82600,'Blue','House')

;with cte as (
    select [ID-Begin] ,[ID-End] ,Color,Dwelling
    from @content
    union all
    select [ID-Begin]+1,[ID-End],Color,Dwelling
    from cte
    where [ID-Begin]+1<=[ID-End]
    )
    select [Id-Begin],Color,Dwelling from cte order by [ID-Begin] 
    option (maxrecursion 10000)

Answer 2

你可以用这样的递归 CTE 来做到这一点

;WITH temp AS
(
   SELECT 1 AS ID 
   UNION ALL 
   SELECT t.ID + 1 FROM temp t
   WHERE t.ID < 100000
) -- return table with id from 1 to 100000
SELECT t.ID,  y.Color, y.Dwelling
FROM YourTable y
INNER JOIN temp t ON t.ID BETWEEN y.IdBegin AND y.IdEnd
OPTION (MAXRECURSION 0)
