简单问题，新建指定间隔数的表
请教如何用cte即with as新建id号指定间隔的表，如：
指定间隔2行
表1
id
1
4
7
10
.
.
.
指定间隔3行
表2
id
1
5
9
13
...
谢谢各位

DECLARE @i INT 
SET @i=2

;WITH cte AS 
(
SELECT number
from master..spt_values
WHERE type='p' AND number>0
AND number %(@i+1)=1
)
SELECT * FROM cte

/*
number
-----------
1
4
7
10
13
16
19
22
25
28
31
34
37
40
43
*/

用cte的递归实现：

DECLARE @i INT 
SET @i=3   --隔开3行
 
;WITH t AS 
(
SELECT 1 as number

union all

select number + @i+1
from t
WHERE number < 10000
)

SELECT * 
FROM t
where number < 50
option(maxrecursion 10000)
/*
number
1
5
9
13
17
21
25
29
33
37
41
45
49
*/

[解决办法]
;WITH cte AS
(
SELECT id=1
UNION ALL
SELECT id+2 FROM cte
WHERE id<10000
)
SELECT * FROM cte OPTION (MAXRECURSION 0);
