mysql - SQL:对结果列表运行嵌套查询

Question

因此，查询 A 获取查询 B 的结果(包含 4 个数字的列表)并对其进行查询。我该如何使用语法呢？ SQL 似乎只喜欢当我只有 1 个值用作输入时。有什么建议吗？

select servers.hostname,
SUM(enm_amos_commands.successcount) AS successCommandCount, 
SUM(enm_amos_commands.failurecount) AS failedCommandCount,
ROUND(AVG(enm_amos_commands.successcount+enm_amos_commands.failureCount),0) AS avg_per_minute, 
MAX(enm_amos_commands.successcount+enm_amos_commands.failureCount) AS max_per_minute 

from enm_amos_commands, servers
where servers.id IN 
(
SELECT 
    servers.id
FROM
    servers
WHERE
    servers.hostname LIKE '%111-scp%' or servers.hostname LIKE '%111-amos%'
    and servers.siteid = 6)

Answer 1

只需使用加入。我猜你打算:

select s.hostname,
       SUM(eac.successcount) AS successCommandCount, 
       SUM(eac.failurecount) AS failedCommandCount,
       ROUND(AVG(eac.successcount + eac.failureCount), 0) AS avg_per_minute, 
       MAX(eac.successcount + eac.failureCount) AS max_per_minute 
from enm_amos_commands eac join
     servers s
     on eac.server_id = s.id
where (s.hostname like '%111-scp%' or s.hostname LIKE '%111-amos%') and
      s.siteid = 6
group by s.hostname;
