这是我的整个要求以及创建和插入命令。
create table sample
( schedule_id varchar2(256),
schedule_details varchar2(256),
pod_name varchar2(256),
milestone varchar2(256),
metric_column varchar2(256),
metric_value varchar2(4000));
insert into sample values ('23456','details','ABCD','M1','status','DONE');

insert into sample values ('7890','det','ABCD','M3','progress','GREEN');
insert into sample values ('7890','det','ABCD','M3','last_reported','2016-04-20 04:18:56');

我的输出是
SCHEDULE_ID | STATUS_DONE | STATUS_SKIP | STATUS_FAILED | STATUS_TOTAL | PROGRESS_RED | PROGRESS_GREEN | PROGRESS_YELLOW | PROGRESS_TOTAL
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------
123456 | 1 | 1 | 0 | 2 | 1 | 0 | 1 | 2
7890 | 0 | 2 | 0 | 2 | 0 | 1 | 1 | 2
查询需要为每个schedule_id获取不同数量的pod_name。对于每个pod，它需要采用里程碑的metric_column-＆gt;状态和metric_column-＆gt;进度，其中包含最新的metric_column-＆gt; last_reported。因此，STATUS_DONE的值是具有最新里程碑（基于last_reported）的POD_NAME的数量，状态为DONE。
例如对于时间表ID 123456，pod ABCD，需要采用里程碑M3的状态和进度，因为M3与M1和M2相比具有最新的last_report。
我的查询具有不同的pod名称，而没有考虑最新的里程碑。
