MySQL按行查询和数

我想逐行总结一下。有什么捷径吗

当前查询：

select t1.name as domain, cast(sum(t2.http_out)/1024/1024/1024 as decimal(8,2)) as HTTP_out_GB, cast(sum(t2.ftp_out)/1024/1024/1024 as decimal(8,2)) as FTP_out_GB, cast(sum(t2.smtp_out)/1024/1024/1024 as decimal(8,2)) as SMTP_out_GB, cast(sum(t2.pop3_imap_out)/1024/1024/1024 as decimal(8,2)) as POP_IMAP_out_GB from domains t1 join DomainsTraffic t2 on t1.id = t2.dom_id where t2.date BETWEEN '2014-02-01 00:00:00' AND '2014-02-28 23:59:59' group by domain; 例如：

+--------------------------------+-------------+------------+-------------+-----------------+ | domain | HTTP_out_GB | FTP_out_GB | SMTP_out_GB | POP_IMAP_out_GB | +--------------------------------+-------------+------------+-------------+-----------------+ | abc.com | 0.00 | 0.00 | 0.08 | 0.39 | | def.com | 0.00 | 0.00 | 1.84 | 2.45 | | fgh.com | 0.00 | 0.00 | 0.00 | 0.00 | 所需：

+--------------------------------+-------------+------------+-------------+-----------------+-----------------+ | domain | HTTP_out_GB | FTP_out_GB | SMTP_out_GB | POP_IMAP_out_GB | TOTAL | +--------------------------------+-------------+------------+-------------+-----------------+-----------------+ | abc.com | 0.00 | 0.00 | 0.08 | 0.39 | 0.47 | def.com | 0.00 | 0.00 | 1.84 | 2.45 | 4.29 | fgh.com | 0.00 | 0.00 | 0.00 | 0.00 | 0.00 您是否尝试将HTTP\u out\u GB+FTP\u out\u GB+SMTP\u out\u GB添加为总计

select domain, HTTP_out_GB, FTP_out_GB, SMTP_out_GB, POP_IMAP_out_GB,
(HTTP_out_GBFTP_out_GB + SMTP_out_GB + POP_IMAP_out_GB) as total from(
select t1.name as domain, cast(sum(t2.http_out)/1024/1024/1024 as decimal(8,2)) as HTTP_out_GB, cast(sum(t2.ftp_out)/1024/1024/1024 as decimal(8,2)) as FTP_out_GB, cast(sum(t2.smtp_out)/1024/1024/1024 as decimal(8,2)) as SMTP_out_GB, cast(sum(t2.pop3_imap_out)/1024/1024/1024 as decimal(8,2)) as POP_IMAP_out_GB 
from domains t1 join DomainsTraffic t2 on t1.id = t2.dom_id 
where t2.date BETWEEN '2014-02-01 00:00:00' AND '2014-02-28 23:59:59' 
group by domain) as A
