获取给定规则的表的特定行 SQL Server 2008
我有一个像这样的表:
ID NAME VAL
----------------------
1 a1*a1 90052
2 a1*a2 236
3 a1*a3 56
4 a1*a4 6072
5 a1*a5 1004
6 a2*a2 4576
7 a2*a3 724
8 a2*a4 230
9 a2*a5 679
10 a3*a3 5
11 a3*a4 644
12 a3*a5 23423
13 a4*a4 42354
14 a4*a5 10199
15 a5*a5 10279
给定一个数字 S = 5,我想查询 id 的行:1,6,10,13,15 它们是 a1*a1,a2*a2,a3*a3,a4*a4 和 a5*a5
我想要类似的东西:
INSERT #NEW_TABLE (ID,NAME,Value) (
SELECT ordinal, NAME, VAL FROM myTable where id = 1,6,10,13,15)
有
ID NAME VAL
----------------------
1 a1*a1 90052
2 a2*a2 4576
3 a3*a3 5
4 a4*a4 42354
5 a5*a5 10279
没有办法对任何给定的 S 执行此操作,也许有动态sql?
我得到了公式,得到了这个:
S=5
ID formula
1 1
6 1+S
10 1+S+ (S-1)
13 1+S+ (S-1) + (S-2)
15 1+S+ (S-1) + (S-2) + (S-3)
有没有办法在 case 或 while 循环内执行此操作?
I have a table like:
ID NAME VAL
----------------------
1 a1*a1 90052
2 a1*a2 236
3 a1*a3 56
4 a1*a4 6072
5 a1*a5 1004
6 a2*a2 4576
7 a2*a3 724
8 a2*a4 230
9 a2*a5 679
10 a3*a3 5
11 a3*a4 644
12 a3*a5 23423
13 a4*a4 42354
14 a4*a5 10199
15 a5*a5 10279
Given a number given S = 5, I want to query
the rows wth id: 1,6,10,13,15
they are a1*a1,a2*a2,a3*a3,a4*a4 and a5*a5
I would like something like:
INSERT #NEW_TABLE (ID,NAME,Value) (
SELECT ordinal, NAME, VAL FROM myTable where id = 1,6,10,13,15)
to get
ID NAME VAL
----------------------
1 a1*a1 90052
2 a2*a2 4576
3 a3*a3 5
4 a4*a4 42354
5 a5*a5 10279
Is there a way to do this for any given S, Maybe wth dynamic sql?
I was getting the formula and I got this:
S=5
ID formula
1 1
6 1+S
10 1+S+ (S-1)
13 1+S+ (S-1) + (S-2)
15 1+S+ (S-1) + (S-2) + (S-3)
Is there a way to do this inside a case or a while loop?

这在测试中起作用了。
您可以仅在
@Tab
上进行内部联接来限制您的结果。您可能还想为低于 3 的值添加一些陷阱,但我还没有这样做。基本过程是
@s-2 次
尝试:
要在查询中使用它,您可以执行以下任一操作:
This worked in testing.
You can just inner join on
@Tab
to limit your results. You probably also want to add some traps for values below 3, which I haven't done.The basic process is

To use this in your query, you can do either:
