Question

如何在单独的列上显示多个mysql查询的输出，下面的代码不起作用并包含3个查询，但是我可以让它在2个查询中工作，见下文

包含3个子查询的mysql查询：

Select (
SELECT (
        SELECT count(s2.centerpoint_stream_stable)
        FROM status_log s2
        WHERE s2.centerpoint_stream_stable = 'Disconnected/ Reconnected to Stream'
        AND s2.date > date_sub(NOW(), INTERVAL 1 minute)  
        ) AS centerpoint_stream_no_disconnects,

count(centerpoint_stream_stable) from status_log where  centerpoint_stream_stable = 'Disconnected/ Reconnected to Stream' and  date > date_sub(now(), interval 6 hour) ) AS a,b,       



s.date, s.website_online, s.icecast_source_online, s.icecast_source_ip,
s.icecast_no_listeners, s.centerpoint_online, s.centerpoint_connection,
s.centerpoint_stream_stable, s.centerpoint_stream_status,  s.horsleypark_online,
s.horsleypark_connection, s.horsleypark_stream_stable, s.horsleypark_stream_status,
s.local_primary_internet_online, s.local_primary_internet_ping,
s.local_primary_instreamer_online, s.local_secondary_internet_online,
s.local_secondary_internet_ping, s.local_secondary_instreamer_online, s.system_ok
FROM status_log s
WHERE id = (select max(id) from status_log)

mysql查询2（工作）：

SELECT (
        SELECT count(s2.centerpoint_stream_stable)
        FROM status_log s2
        WHERE s2.centerpoint_stream_stable = 'Disconnected/ Reconnected to Stream'
        AND s2.date > date_sub(NOW(), INTERVAL 1 minute)  
        ) AS centerpoint_stream_no_disconnects,


s.date, s.website_online, s.icecast_source_online, s.icecast_source_ip,
s.icecast_no_listeners, s.centerpoint_online, s.centerpoint_connection,
s.centerpoint_stream_stable, s.centerpoint_stream_status,  s.horsleypark_online,
s.horsleypark_connection, s.horsleypark_stream_stable, s.horsleypark_stream_status,
s.local_primary_internet_online, s.local_primary_internet_ping,
s.local_primary_instreamer_online, s.local_secondary_internet_online,
s.local_secondary_internet_ping, s.local_secondary_instreamer_online, s.system_ok
FROM status_log s
WHERE id = (select max(id) from status_log)

输出

Answer 1

select * from
    (select count(centerpoint_stream_stable) from status_log where  centerpoint_stream_stable = 'Disconnected/ Reconnected to Stream' and  date > date_sub(now(), interval 6 hour)) as T1
    ,
    (select count(centerpoint_stream_stable) from status_log where  centerpoint_stream_stable = 'Disconnected/ Reconnected to Stream' and  date > date_sub(now(), interval 6 hour) ) as T2
    ,
    (select  s.date, s.website_online, s.icecast_source_online, s.icecast_source_ip,
       s.icecast_no_listeners, s.centerpoint_online, s.centerpoint_connection,
       s.centerpoint_stream_stable, s.centerpoint_stream_status,  s.horsleypark_online,
       s.horsleypark_connection, s.horsleypark_stream_stable, s.horsleypark_stream_status,
