php - mySql 返回不正确的结果

Question

我有一个问题

SELECT date, SUM(cimpression) AS cimp, SUM(cclick) AS cclick 
FROM stdaily 
WHERE date BETWEEN :start AND :end 
AND (id = 21 AND id = 32 AND id = 12 AND id = 33)
GROUP BY date
ORDER BY date ASC;

此查询只需要返回 id 等于 21、32、12 和 33 的结果，但返回的结果不包含这些特定的 ID，不确定到底出了什么问题？有什么建议吗？

Answer 1

我认为您正在寻找的是:

SELECT date,SUM(cimpression) AS cimp, SUM(cclick) AS cclick
FROM stdaily
WHERE date BETWEEN :start AND :end 
AND id in (21, 32, 12, 33) 
GROUP BY date 
ORDER BY date ASC;

这将返回结果，其 ID 与 in 括号中包含的任何结果相同。
