Question

这是我的查询...我正在尝试找到所有拥有多个容器的BLNUMBERS，其中所有容器都是＆＃39; status =＆＃39;＆＃39;。为什么这不起作用？我现在正在买一些所有容器的BLNUMBERS。 status =＆＃39;＆＃39;还有一些地位＆lt;＆gt;＆＃39;＆＃39;编辑：我如何找到BLNUMBERS哪里有一些容器＆＃39; status =＆＃39;＆＃39;和一些容器＆＃39;状态＆lt;＆gt; ＆＃39;＆＃39;

 SELECT
     DISTINCT
     BLNUMBER
     #,CONTAINERNUMBER
     ,COUNT(CONTAINERNUMBER) AS COUNT
 FROM   
     SHIPMENTS
 WHERE
      BLNUMBER <> ''
      AND CDATE > NOW() - INTERVAL 1 MONTH
      AND CDATE < NOW() - INTERVAL 7 DAY
      AND CONTAINERNUMBER <> ''
      AND CONTAINERNUMBER NOT LIKE '.AIR%'
      AND CONTAINERNUMBER NOT LIKE 'AIR%'
      AND CARRIER_ID <>8
      AND STATUS = ''
  GROUP BY 
      BLNUMBER
  HAVING
      COUNT > 1

Answer 1

因此，如果我理解正确，您想要选择BLNUMBERS CONTAINER的{{1}} BLNUMBER为空STATUS的所有BLNUMBERS，这意味着您要排除CONTAINER至少有一个STATUS非空CONTAINER？

为此，我会根据BLNUMBER计算CONTAINER s的总数，然后计算每STATUS个空白BLNUMBER的总数BLNUMBERS，然后只返回总CONTAINER次数等于空白CONTAINER s的SELECT totalBlanks.BLNUMBER, totalBlanks.`count` FROM (SELECT BLNUMBER, COUNT(*) `count` FROM SHIPMENTS GROUP BY BLNUMBER) totals LEFT JOIN (SELECT BLNUMBER, COUNT(*) `count` FROM SHIPMENTS WHERE `STATUS` = '' GROUP BY BLNUMBER) totalBlanks ON totals.BLNUMBER = totalBlanks.BLNUMBER WHERE totals.`count` = totalBlanks.`count`。

所以

{{1}}

Answer 2

以下查询获取具有任何容器且没有状态的所有BLNUMBER：

SELECT DISTINCT BLNUMBER
FROM SHIPMENTS
WHERE BLNUMBER <> '' AND
      CDATE > NOW() - INTERVAL 1 MONTH AND
      CDATE < NOW() - INTERVAL 7 DAY AND
      CONTAINERNUMBER <> '' AND
      CONTAINERNUMBER NOT LIKE '.AIR%' AND
      CONTAINERNUMBER NOT LIKE 'AIR%' AND
      CARRIER_ID <> 8 
GROUP BY BLNUMBER, CONTAINERNUMBER
HAVING MAX(STATUS) > '';

要获得具有多个容器的容器需要额外级别的子查询：

SELECT BLNUMBER
FROM (SELECT BLNUMBER, CONTAINERNUMBER
      FROM SHIPMENTS
      WHERE BLNUMBER <> '' AND
            CDATE > NOW() - INTERVAL 1 MONTH AND
            CDATE < NOW() - INTERVAL 7 DAY AND
            CONTAINERNUMBER <> '' AND
            CONTAINERNUMBER NOT LIKE '.AIR%' AND
            CONTAINERNUMBER NOT LIKE 'AIR%' AND
            CARRIER_ID <> 8 
      GROUP BY BLNUMBER, CONTAINERNUMBER
      HAVING MAX(STATUS) > ''
     ) b
GROUP BY BLNUMBER
HAVING COUNT(*) >= 2;

数数＆＃39; HAVING＆＃39;所有记录都有列=＆＃39;＆＃39;
