Oracle中如何用Order by查询数据Group by

Question

我有这样的示例数据

CREATE TABLE table_name (aktif, "START", "END", NO_BOX, QTY) AS
SELECT 1, 'A0001', 'A0020', 2016, 100 FROM DUAL UNION ALL
SELECT 1, 'A0021', 'A0040', 2016, 100 FROM DUAL UNION ALL
SELECT 1, 'A0041', 'A0060', 2016, 100 FROM DUAL UNION ALL
SELECT 0, 'A0061', 'A0080', NULL, 100 FROM DUAL UNION ALL
SELECT 0, 'A0081', 'A0100', NULL, 100 FROM DUAL UNION ALL
SELECT 1, 'A0101', 'A0120', 2016, 100 FROM DUAL UNION ALL
SELECT 1, 'A0121', 'A0140', 2016, 100 FROM DUAL UNION ALL
SELECT 1, 'A0141', 'A0160', 2016, 100 FROM DUAL UNION ALL
SELECT 0, 'A0161', 'A0180', NULL, 100 FROM DUAL UNION ALL
SELECT 0, 'A0181', 'A0200', NULL, 100 FROM DUAL;

我想根据行的顺序对 AKTIF 和 NO_BOX 保持不变的列进行分组，然后 select SUM(QTY)、MIN(START), MAX(END).

输出应该是：

AKTIF	START	END	NO_BOX	QTY
1	A0001	A0060	2016	300
0	A0061	A0100	NULL	200
1	A0101	A0160	2016	300
0	A0161	A0200	NULL	200

归根结底，这就是差距和孤岛问题。

示例数据：

SQL> with test (aktif, cstart, end, no_box, qty) as
  2    (select 1, 'A0001', 'A0020', 2016, 100 from dual union all
  3     select 1, 'A0021', 'A0040', 2016, 100 from dual union all
  4     select 1, 'A0041', 'A0060', 2016, 100 from dual union all
  5     --
  6     select 0, 'A0061', 'A0080', null, 100 from dual union all
  7     select 0, 'A0081', 'A0100', null, 100 from dual union all
  8     --
  9     select 1, 'A0101', 'A0120', 2016, 100 from dual union all
 10     select 1, 'A0121', 'A0140', 2016, 100 from dual union all
 11     select 1, 'A0141', 'A0160', 2016, 100 from dual union all
 12     --
 13     select 0, 'A0161', 'A0180', null, 100 from dual union all
 14     select 0, 'A0181', 'A0200', null, 100 from dual
 15    ),

查询从这里开始：

 16  temp as
 17    (select t.*,
 18       row_number() over (order by cstart) -
 19       row_Number() over (partition by aktif order by cstart) grp
 20     from test t
 21    )
 22  select aktif,
 23    min(cstart) cstart,
 24    max(end) end,
 25    no_box,
 26    sum(qty) qty
 27  from temp
 28  group by aktif, no_box, grp
 29  order by cstart;

     AKTIF CSTAR END       NO_BOX        QTY
---------- ----- ----- ---------- ----------
         1 A0001 A0060       2016        300
         0 A0061 A0100                   200
         1 A0101 A0160       2016        300
         0 A0161 A0200                   200
