Question

我有一张包含以下数据的表格

Order_no | Part_No    | R_from | R_to
    1001 | 1010037-00L|      1 |    5
    1001 | 1010025-00L|      6 |   12

我需要以下面的方式将上述数据提供给报告。

R_NO | PART_NO
------------------
   1 | 1010037-00L
   2 | 1010037-00L
   3 | 1010037-00L
   4 | 1010037-00L
   5 | 1010037-00L
   6 | 1010025-00L
   7 | 1010025-00L
   8 | 1010025-00L
   9 | 1010025-00L
  10 | 1010025-00L
  11 | 1010025-00L
  12 | 1010025-00L

Answer 1

类似的东西：

WITH r_nos ( r_no ) AS (
  SELECT LEVEL
  FROM   DUAL
  CONNECT BY LEVEL <= ( SELECT MAX( R_to ) FROM your_table )
)
SELECT r_no,
       part_no
FROM   r_nos r
       INNER JOIN
       your_table y
       ON ( r.r_no BETWEEN y.r_from AND y.r_to )

Answer 2

这是一种不需要单独连接的替代方案。您应该测试两种解决方案，以确定哪种解决方案更适合您的数据等。

   ID variable       Date Balance
1:  1        1 01-01-2014   10000
2:  2        1 01-01-2015   50000
3:  3        1 01-08-2014   30000
4:  4        1 01-02-2016    5000
5:  1        2 01-02-2017    5000
6:  2        2 01-02-2016   30000
7:  3        2 01-02-2015   15000
8:  4        2 01-02-2018    3500
