Mysql 完全连接两个查询

此查询返回了385个字符串

SELECT order_number
FROM `order` 
inner join order_delivery_data on `order`.order_id = order_delivery_data.order_id
where order_status = 'delivered' AND order_statusUpdatedAt >= DATE_SUB(CURRENT_DATE, INTERVAL 7 DAY)
and order_delivery_data_name in ('London')

这返回了74个字符串

SELECT order_number
FROM `order` 
inner join order_delivery_data on `order`.order_id = order_delivery_data.order_id
where order_status = 'delivered' AND order_statusUpdatedAt BETWEEN  DATE_SUB(CURRENT_DATE, INTERVAL 10 DAY) 
AND  DATE_SUB(CURRENT_DATE, INTERVAL 7  DAY)
and order_delivery_data_name in ('London')

如何连接它，因为有两列

您需要使用完全连接，即使用mysql时使用UNION ALL：

 try this:
 SELECT t1.order_number as order_t1, t2.order_number as order_t2 FROM
        (       SELECT order_number,`order`.order_id 
                FROM `order` 
                inner join order_delivery_data on `order`.order_id = order_delivery_data.order_id
                where order_status = 'delivered' AND order_statusUpdatedAt BETWEEN  DATE_SUB(CURRENT_DATE, INTERVAL 10 DAY) 
                AND  DATE_SUB(CURRENT_DATE, INTERVAL 7  DAY)
                and order_delivery_data_name in ('London')

        ) as t1
        LEFT JOIN
        (SELECT order_number,`order`.order_id 
                FROM `order` 
                inner join order_delivery_data on `order`.order_id = order_delivery_data.order_id
                where order_status = 'delivered' AND order_statusUpdatedAt BETWEEN  DATE_SUB(CURRENT_DATE, INTERVAL 10 DAY) 
                AND  DATE_SUB(CURRENT_DATE, INTERVAL 7  DAY)
                and order_delivery_data_name in ('London')
        ) as t2
        ON t1.order_id  = t2.order_id
    UNION ALL
        SELECT t1.order_number as order_t1, t2.order_number as order_t2 FROM
        (       SELECT order_number,`order`.order_id 
                FROM `order` 
                inner join order_delivery_data on `order`.order_id = order_delivery_data.order_id
                where order_status = 'delivered' AND order_statusUpdatedAt BETWEEN  DATE_SUB(CURRENT_DATE, INTERVAL 10 DAY) 
                AND  DATE_SUB(CURRENT_DATE, INTERVAL 7  DAY)
                and order_delivery_data_name in ('London')

        ) as t1
        RIGHT JOIN
        (SELECT order_number,`order`.order_id 
                FROM `order` 
                inner join order_delivery_data on `order`.order_id = order_delivery_data.order_id
                where order_status = 'delivered' AND order_statusUpdatedAt BETWEEN  DATE_SUB(CURRENT_DATE, INTERVAL 10 DAY) 
                AND  DATE_SUB(CURRENT_DATE, INTERVAL 7  DAY)
                and order_delivery_data_name in ('London')
        ) as t2
        ON t1.order_id  = t2.order_id;

第一个\u query UNION所有第二个\u query UNION

UNION返回一列459个字符串，我需要两列385和74个字符串。两个查询的时间范围相同，我更改了它。但现在它在第一列显示385值，在第二列显示零。可能是因为t1.order\u id=t2.order\u id上的

？两列中没有相同的order_id，正是出于这个原因，这就是我建议使用union的原因。通过模拟完全外部联接来编辑我的答案。将使用两个查询中的数据重新返回一列。我需要两个列，每个列都有数据，每个请求使用不同的别名：（第一个查询）作为“第一个7天”UNION ALL（第二个查询）作为“下一个3天”
