mysql - 如何在 MySQL 中查询和分组每个连续的数字系列？

Question

我有这个 shipping.or_nos 表，其中包含一系列收据编号。我想列出所有正在发出的或不包括 status='Cancelled' 使系列分成组。例如，我有这个收据 stab 125001-125050，并且 125020 被取消，所以列表结果将是：

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

这似乎是一个棘手的问题。

感谢您的阅读，但我已经做到了，就在现在！:) 这是我的查询（忽略它构成我们的 CGI 的其他字符）：

{.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}
