Question

我真的需要一些帮助。不是MySQL友好，在过去的几天里混乱，但现在卡住了......

需要采取以下查询并修改它以仅提取例如在“1月”的月份关闭的记录。这可能来自下面吗？无法想象......

<?php
$recentlyClosedDays = 7;
?>


$query1 = "
SELECT HD_TICKET.ID as ID, 
HD_TICKET.TITLE as Title, 
HD_STATUS.NAME AS Status, 
HD_PRIORITY.NAME AS Priority, 
HD_TICKET.CREATED as Created, 
HD_TICKET.MODIFIED as Modified, 
S.FULL_NAME  as Submitter, 
O.FULL_NAME  as Owner, 
HD_TICKET.RESOLUTION as Resolution,
(SELECT COMMENT FROM HD_TICKET_CHANGE WHERE HD_TICKET_ID=HD_TICKET.ID ORDER BY TIMESTAMP DESC LIMIT 1) as Comment,
HD_TICKET.CUSTOM_FIELD_VALUE0 as Type  
FROM HD_TICKET  
JOIN HD_STATUS ON (HD_STATUS.ID = HD_TICKET.HD_STATUS_ID) 
JOIN HD_PRIORITY ON (HD_PRIORITY.ID = HD_TICKET.HD_PRIORITY_ID) 
LEFT JOIN USER S ON (S.ID = HD_TICKET.SUBMITTER_ID) 
LEFT JOIN USER O ON (O.ID = HD_TICKET.OWNER_ID)
WHERE (HD_TICKET.HD_QUEUE_ID = $mainQueueID)
AND (HD_STATUS.STATE like '%Closed%')  
AND (HD_TICKET.TIME_CLOSED >= DATE_SUB(NOW(), INTERVAL $recentlyClosedDays DAY))
ORDER BY HD_TICKET.TIME_CLOSED DESC
";

任何帮助都会大大增加，啤酒将被拖欠：）

要在当前月份中选择DATE，DATETIME或TIMESTAMP值，请执行此操作。

WHERE timestampval >= DATE(DATE_FORMAT(NOW(), '%Y-%m-01'))
  AND timestampval <  DATE(DATE_FORMAT(NOW(), '%Y-%m-01')) + INTERVAL 1 MONTH

对于上个月，您可以这样做：

WHERE timestampval >= DATE(DATE_FORMAT(NOW(), '%Y-%m-01')) - INTERVAL 1 MONTH
  AND timestampval <  DATE(DATE_FORMAT(NOW(), '%Y-%m-01'))

对于去年，您可以这样做：

WHERE timestampval >= DATE(DATE_FORMAT(NOW(), '%Y-01-01')) - INTERVAL 1 YEAR
  AND timestampval <  DATE(DATE_FORMAT(NOW(), '%Y-01-01'))

您可以按月汇总（汇总）表格：

SELECT DATE(DATE_FORMAT(timestampval , '%Y-%m-01')) AS month_starting,
       SUM(whatever) AS total,
       COUNT(whatever) AS transactions
  FROM table
 GROUP BY DATE(DATE_FORMAT(timestampval , '%Y-%m-01'))

这一切都有效，因为这个表达式：

DATE(DATE_FORMAT(sometime, '%Y-%m-01'))

采用任意sometime值并返回发生时间戳的月份的第一天。同样，

DATE(DATE_FORMAT(sometime, '%Y-01-01'))

返回一年的第一天。然后，您可以使用+ INTERVAL 1 MONTH之类的日期算法来操纵几个月或几年的前几天。

MySQL查询结果基于月份
