Question

我正在使用此查询遇到很多问题。它似乎没有正确计算行数，而且它缺少很多。

基本上，我在这里使用了2个表。一个用于leads，另一个用于assignments。每个潜在客户都可以多次分配，因此它可以在assignments表中有多行。 dealerships表仅用于确保它不计算某些经销商的行数。

我想在这里做的只是计算来自每个网站的潜在客户数量，并按日，周，月等细分。

以下是查询中使用的每个表的结构：

--
-- Table structure for table `assignments`

  `id` int(11) NOT NULL auto_increment,

以下是我正在使用的查询：

select 
l.website,
sum(case when date_format(from_unixtime(COALESCE(a.date_assigned, l.date_added)), '%Y-%m-%d') = date_format(now(), '%Y-%m-%d') then 1 else 0 end) AS c_day,
sum(case when date_format(from_unixtime(COALESCE(a.date_assigned, l.date_added)), '%Y-%m-%d') = date_format(now() - interval 1 day, '%Y-%m-%d') then 1 else 0 end) AS c_yesterday,

sum(case when date_format(from_unixtime(COALESCE(a.date_assigned, l.date_added)), '%Y-%m-%d') = date_format(now() - interval 4 day, '%Y-%m-%d') then 1 else 0 end) AS c_4_days,

sum(case when date_format(from_unixtime(COALESCE(a.date_assigned, l.date_added)), '%Y')= date_format(now(), '%Y') then 1 else 0 end) AS c_year  
from `leads` as l
left join `assignments` as a on (a.id_lead = l.id)
left join `dealerships` as d on (d.id = a.id_dealership)
where a.is_reassign='no' and a.id_dealership not in ('65', '77', '89', '138', '175', '177')
group by l.website
order by l.website asc

有一点需要注意的是，有时导致date_added表中缺少leads字段，但导致date_assigned的{{1}}存在反之亦然。

为什么我的查询无法正常运行？任何帮助将不胜感激。
