Question

是否可以从连接查询中选择全部，我想回显出属于用户的数据包表中的所有数据，而不是连接每一列？

这是我的SQL查询：

SELECT ip_address, SUM(upload_bytes) as upload_bytes, SUM(download_bytes) as 
download_bytes, 
        sum(upload_bytes + download_bytes) as totalbytes, package_id, 
username 
        FROM 
        (
           (SELECT ipaccounting.src_address as ip_address, 
SUM(ipaccounting.bytes) AS upload_bytes, 0 as download_bytes, 
            users.username, datapackages.package_id 
            FROM ipaccounting
            join users on users.ipaddress = ipaccounting.src_address
            join datapackages on datapackages.package_id = users.datapackage
            WHERE dst_address NOT BETWEEN INET_NTOA('192.168.0.1') AND 
INET_NTOA('192.168.255.254')  
            GROUP BY src_address)
        UNION ALL 
           (SELECT ipaccounting.dst_address as ip_address, 0 AS 
upload_bytes, SUM(ipaccounting.bytes) as download_bytes, 
            users.username, datapackages.package_id
            FROM ipaccounting 
            join users on users.ipaddress = ipaccounting.dst_address
            join datapackages on datapackages.package_id = users.datapackage
            WHERE src_address NOT BETWEEN INET_NTOA('192.168.0.1') AND 
INET_NTOA('192.168.255.254')  
            GROUP BY dst_address)
        ) a 
        GROUP BY ip_address 
        ORDER BY INET_ATON(ip_address)

试试这个

SELECT ip_address, 
SUM(IF(ipaccounting.src_address != NULL, ipaccounting.bytes, 0)) as upload_bytes, 
SUM(IF(ipaccounting.dst_address != NULL, ipaccounting.bytes, 0)) as download_bytes, 
sum(ipaccounting.bytes) as totalbytes, 
package_id, username 
FROM ipaccounting
join users on users.ipaddress = ipaccounting.src_address OR users.ipaddress = ipaccounting.dst_address
join datapackages on datapackages.package_id = users.datapackage
WHERE ipaccounting.dst_address NOT BETWEEN INET_NTOA('192.168.0.1') AND INET_NTOA('192.168.255.254') 
AND ipaccounting.src_address NOT BETWEEN INET_NTOA('192.168.0.1') AND INET_NTOA('192.168.255.254') 
GROUP BY src_address,dst_address ORDER BY INET_ATON(src_address),INET_ATON(dst_address)

要获得更准确的查询，请发布表格结构和示例数据。

Answer 2

我很久以前问这个问题时，已经不记得这是否是正确的答案，但是如果我能正确记住，我在寻找的答案与此类似：

SELECT 
    devices.*, 
    device_info.* 
FROM devices
LEFT JOIN device_info ON devices.id = device_info.device_id

在连接查询SQL上选择全部
