Question

我无法让查询工作。此查询中使用了4个表。我想要一份看起来像这样的报告......

Name Success Failure jdn 5 1 wer 0 3

我想生成过去24小时的数据。这是我尝试过但没有用的示例查询。

select r.name as jid,
 i.id as theid,
 (select sum(counter) as scount 
  from WebServicesIfSummarySuccess 
  where id=theid 
    and dtime between date_sub(now(),interval 24 hour) and now() 
    and sum(counter) >0 and sum(counter) is not null 
  group by id
 ) as success,
 (select sum(counter) as fcount 
  from WebServicesIfSummaryFailure 
  where id=theid 
    and dtime between date_sub(now(),interval 24 hour) and now() 
    and sum(counter) >0 and sum(counter) is not null 
  group by id
 ) as failure
 from router r, interface i 
 where r.rid = i.rid  
 and r.name like '%wi%' ;

以下是表格布局。
