具有多个 WHERE 的 MySQL 多个 JOIN 子句

Question

这是第三次编辑。根据您的所有反馈，我能够使用多个搜索条件生成以下查询。

请注意，这是一个现有系统，预算存在问题，因此我正在尽我所能改进现有查询。您看到的搜索是基于数组手动完成的，没有连接。同样的搜索需要 2-3 分钟来处理，而感谢所有摇滚大师，现在需要 7-8 秒来处理:)

我知道这可以通过将查找设置值移动到单独的表并在联系人主表和值主表之间创建关系表来进一步改进。但正如我所说，预算对这些人来说是个大问题，所以我想这对他们来说不仅高效。

然而，我们欢迎任何进一步的改进想法。

这是在您的查询中给出错误的部分

INNER JOIN contact_professional_details 
ON contact_professional_details.contact_id = contacts.id
 AND (       <-- Here
INNER JOIN contact_to_categories 
ON contact_to_categories.contactid = contacts.id 
 AND (
contact_to_categories.catid = '2'
)

将此更改为

INNER JOIN contact_professional_details 
ON contact_professional_details.contact_id = contacts.id

INNER JOIN contact_to_categories 
ON contact_to_categories.contactid = contacts.id 
 AND contact_to_categories.catid = '2'

编辑:您发布的查询一团糟，您确实多次加入了同一个表，并且确实使用了链式 OR 条件而不是 IN 子句。因此，下面是您修改后的查询。
