我想在配置单元表中使用case-when，like和正则表达式编写一个查询。我用过 regexp 以及 rlike ，但我没有得到想要的结果。我目前的尝试如下

select distinct ending from
(select date, ending, name, count(distinct id) 
from (select CONCAT_WS("/",year,month,day,hour) as date, id, name,
case when type = 'TRAN' then 'tran'
when events regexp '%[:]no_reply[:]%[^o][^n][:]incomplete[:]%' and type rlike '%HUP' then 'con'
when events not regexp '%[:]no_reply[:]%[^o][^n][:]incomplete[:]%' and type rlike '%HUP'  then 'aban'
else 'other'
end as ending
from data_struct1) tmp
group by date, ending, name) tmp2;

还有

select distinct ending from
    (select date, ending, name, count(distinct id) 
    from (select CONCAT_WS("/",year,month,day,hour) as date, id, name,
    case when type = 'TRAN' then 'tran'
    when events rlike '%[:]no_reply[:]%[^o][^n][:]incomplete[:]%' and type rlike '%HUP' then 'con'
    when events not rlike '%[:]no_reply[:]%[^o][^n][:]incomplete[:]%' and type rlike '%HUP'  then 'aban'
    else 'other'
    end as ending
    from data_struct1) tmp
    group by date, ending, name) tmp2;

两个查询都返回不正确的结果（语法不错，只是结果不正确）。
