如何查询和分组MySQL中的每个连续数字系列？

我有这个运费表，里面有一系列的收据号码。我想列出所有正在发行的or，不包括使系列分组的状态为“已取消”。 例如，我有这个收据stab 125001-125050，125020被取消，因此列表结果是：

+-------------------------------------------------------+
|  OR Start  |    OR End    |   Quantity   |   Amount   |
+-------------------------------------------------------+
| 125001     | 125019       |           19 |            |
+-------------------------------------------------------+
| 125021     | 125050       |           30 |            |
+-------------------------------------------------------+

这似乎是一个很难回答的问题。

谢谢你的阅读，但我刚才已经做到了！：） 这是我的查询（忽略CGI中的其他字符）：

我不确定你需要什么，但根据我的理解，你可以在声明之间使用

{.while SELECT `start`,`end`,or_prefix,or_suffix,SUM(a.amount) AS g_total,COUNT(*) AS qcount FROM (SELECT l.id AS `start`,( SELECT MIN(a.id) AS id FROM ( SELECT a.or_no AS id FROM freight.`or_nos` a WHERE a.status!='Cancelled' AND a.log_user = 0@user_teller AND DATE(a.or_date)='@user_date`DATE'  AND IF(a.status='Default' AND a.amount=0,0,1)  ) AS a LEFT OUTER JOIN ( SELECT a.or_no AS id FROM freight.`or_nos` a WHERE a.status!='Cancelled' AND a.log_user = 0@user_teller AND DATE(a.or_date)='@user_date`DATE'  AND IF(a.status='Default' AND a.amount=0,0,1)    ) AS b ON a.id = b.id - 1 WHERE b.id IS NULL AND a.id >= l.id ) AS `end` FROM ( SELECT a.or_no AS id FROM freight.`or_nos` a WHERE a.status!='Cancelled' AND a.log_user = 0@user_teller AND DATE(a.or_date)='@user_date`DATE' AND IF(a.status='Default' AND a.amount=0,0,1)  ) AS l LEFT OUTER JOIN ( SELECT a.or_no AS id FROM freight.`or_nos` a WHERE a.log_user = 0@user_teller AND DATE(a.or_date)='@user_date`DATE' AND IF(a.status='Default' AND a.amount=0,0,1)  )  AS r ON r.id = l.id - 1 WHERE r.id IS NULL) AS k LEFT JOIN freight.`or_nos` a ON a.`or_no` BETWEEN k.start AND k.end  AND DATE(a.`or_date`)='@user_date`DATE' AND a.log_user =0@user_teller AND IF(a.status='Default' AND a.amount=0,0,1) AND a.status!='Cancelled' GROUP BY `start`}
          {.start}{.x.24.12:end}{.x`p0.40.-5:qcount}{.x`p2.57.-15:g_total}{.asc 255}
{.wend}{.asc 255}
