Mysql 连接两个查询

我有两个问题

`SELECT 
total,from_sale,from_sent,on_sent
FROM deliverability.delivery_count_repo
where add_time >= CURDATE()`

及

我试着加入这个

但是出了点问题。每个派生表都必须有自己的别名错误

才能将一个结果集连接到另一个结果集，通常最好使用UNION ALL

但是，我怀疑您对SQL的工作原理感到困惑。它处理矩形数据。每个结果集都是这样一个矩形。它有一定数量的列，每个列显示特定类型的信息。而且，每个结果集都有一定数量的行。结果集的每一行都具有与其他每一行相同类型的列

问题中的第一个结果集有四列，第二个结果集有三列。尝试将这些结果塞进一个结果集中没有什么意义。

试试这个 假设“idCommon”是两个表之间的公共id：

`SELECT 
total,from_sale,from_sent,on_sent
FROM deliverability.delivery_count_repo
INNER JOIN (
`SELECT 
  idCommon,
order_customFields.order_customFields_delivery_method method,
  sum(case `order`.order_status when 'paid' then 1 else 0 end) paid,
  sum(case `order`.order_status when 'later' then 1 else 0 end) later
FROM order_customFields 
  INNER JOIN `order` ON order_customFields.order_id = `order`.order_id
WHERE
  order_customFields.order_customFields_order_date >= date_sub(date_sub(curdate(), interval day(curdate()) - 1 day), interval 1 month) and
      order_customFields.order_customFields_order_date < date_sub(curdate(), interval day(curdate()) - 1 day) 
AND order_customFields.order_customFields_delivery_method is not null
GROUP BY    
   order_customFields.order_customFields_delivery_method `

) as t ON t.idCommon=delivery_count_repo.idCommon -- you must cross id's Common

where add_time >= CURDATE()`

您真正想做什么？@Michaelalexandero第一次查询的结果是5行，第二次查询的结果是3行。我想在一个查询中最终得到8行使用联接要求两个查询具有相同的列计数。第一个查询有4列，第二个查询有3列。这是行不通的。

`SELECT 
total,from_sale,from_sent,on_sent
FROM deliverability.delivery_count_repo
INNER JOIN (
`SELECT 
  idCommon,
order_customFields.order_customFields_delivery_method method,
  sum(case `order`.order_status when 'paid' then 1 else 0 end) paid,
  sum(case `order`.order_status when 'later' then 1 else 0 end) later
FROM order_customFields 
  INNER JOIN `order` ON order_customFields.order_id = `order`.order_id
WHERE
  order_customFields.order_customFields_order_date >= date_sub(date_sub(curdate(), interval day(curdate()) - 1 day), interval 1 month) and
      order_customFields.order_customFields_order_date < date_sub(curdate(), interval day(curdate()) - 1 day) 
AND order_customFields.order_customFields_delivery_method is not null
GROUP BY    
   order_customFields.order_customFields_delivery_method `

) as t ON t.idCommon=delivery_count_repo.idCommon -- you must cross id's Common

where add_time >= CURDATE()`
