Php mysql与条件的一对多关系

我有两个表事件和事件可见性

SELECT Event.*, EventVisibility.* FROM events AS Event 
LEFT JOIN events_visibility AS EventVisibility
ON 
  (Event.id = EventVisibility.event_id) 
WHERE 
 'Event.all' = 1 
 OR 
  (
    'EventVisibility.visible_to_id' = 2 AND 
    'EventVisibility.visible_to' = 159
 )

事件表和列

id - title - all

事件的可见性及其列

id - event_id - visibile_to - visibile_to_id

这里的visibile_是指可以看到此事件的用户。这里可以看到A组、B组、C组，因此一个事件可以在事件\ U可见性中有多个条目

SELECT Event.*, EventVisibility.* FROM events AS Event 
LEFT JOIN events_visibility AS EventVisibility
ON 
  (Event.id = EventVisibility.event_id) 
WHERE 
 'Event.all' = 1 
 OR 
  (
    'EventVisibility.visible_to_id' = 2 AND 
    'EventVisibility.visible_to' = 159
 )

我想根据可见性获取唯一的事件，如果有的话，类似这样的东西 这个查询没有给我正确的结果

你能看一下吗

可能是你在单引号内写的专栏。试试这个

   SELECT Event.*, EventVisibility.* FROM events AS Event 
    LEFT JOIN events_visibility AS EventVisibility
   ON 
   (Event.id = EventVisibility.event_id) 
   WHERE 
   Event.all = 1 
   OR 
   (
    EventVisibility.visible_to_id = 2 AND 
    EventVisibility.visible_to = 159
    )
