Question

如果名称与stripos($tocheck, "V2")的匹配方式相同，我如何按日期汇总某个值？

如果包含文字，则按日期"name"全部显示 - ＆＃34; V2＆＃34;，如果不清楚请问，我真的不知道如何解释，但我＆＃39;如果需要，我会尝试提供更多信息。

这当前获取所有数据并按天计算它

$sql_download = "SELECT date, name, SUM(quantity) FROM downloads GROUP BY DATE(`Date`)";



`downloads` (`id`, `date`, `name`, `quantity`) VALUES
(1, '2015-05-13 23:30:09', 'CRCP03 - Cartoon Race Car Pack 03', 1),
(2, '2015-05-13 23:30:09', 'CRCPV2-01 - Cartoon Race Cars Pack V2 - 01', 1),
(3, '2015-05-14 00:30:09', 'CRCP03 - Cartoon Race Car Pack 03', 1),
(4, '2015-05-14 00:30:09', 'CRCPV2-01 - Cartoon Race Cars Pack V2 - 01', 1),
(5, '2015-05-14 07:05:07', 'CRCP03 - Cartoon Race Car Pack 03', 1),
(6, '2015-05-14 07:10:07', 'CRCP03 - Cartoon Race Car Pack 03', 1),

Answer 1

您只需添加WHERE条件即可检查name是否匹配：

  SELECT date, name, SUM(quantity)
    FROM downloads
   WHERE name LIKE '%V2%'
GROUP BY DATE(`Date`)

如果名称匹配则按日期计算SUM数量
