Question

我有两个SELECT语句，它们都从dirrefernt表返回13行

我想创建一个包含2列的临时表，并将2个结果行插入到2列中。有没有办法做到这一点？

所以

1 - SELECT INPOS FROM TABLE1返回

1,2,3,4,5,6,7,18,9,10,11,12,13

2 - SELECT CODE FROM TABLE2返回

CODEa所，CODEB，CODEC，编码CODEE，CODEF，CODEG，CODEH，CODEI，CODEJ，CODEK，CODEL，CODEM

我希望我的临时表格

1 | CODEA

2 | CODEB

3 | CODEC

4 | CODED

5 | CODEE

6 | CODEF

7 | CODEG

8 | CODEH

9 | CODEI

10 | CODEJ

11 | CODEK

12 | CODEL

13 | CODEM

Answer 1

试试这个：

WITH T1 AS (
   SELECT ROW_NUMBER() OVER(ORDER BY INPOS) ID, INPOS FROM TABLE1
),
WITH T2 AS
(
   SELECT ROW_NUMBER() OVER(ORDER BY CODE) ID, CODE FROM TABLE2
),
SELECT T1.INPOS, T2.CODE
FROM T1 INNER JOIN T2 ON T1.ID = T2.ID

Answer 2

尝试这样的事情：

SELECT a.impos, b.code
FROM (
  (
    SELECT impos, RANK() OVER (ORDER BY impos ASC) AS link
    FROM table1
    ) AS a INNER JOIN (
    SELECT code, RANK() OVER (ORDER BY code ASC) AS link
    FROM table2
    ) AS b ON a.link = b.link
  )
