我有以下查询，我想子查询 id 与外部查询匹配，并选择与父查询返回的同一行的值。在这里，它在子查询中返回更多结果，我使用限制 1，但是这样我得到了错误的结果。
select
calldate,
linkedid,
src,
case
when group_concat(disposition, ",") like '%ANSWERED%' then (
select dst
from cdr cd
where
disposition = 'Answered'
and cd.linkedid = cdr.linkedid
and cdr.dst = cd.dst
limit 1
)
else dst
end as status,
did,cnum,
case
when group_concat(disposition, ",") like '%ANSWERED%' then 'ANS'
else 'NO Ans'
end as status
from cdr
where
dst in (
select extension
from users
where name like '%ASMARA%' or name like '%aramsa%'
)
and calldate between '2019-10-31' and '2019-11-01'
group by linkedid
以下是样本数据
| linkedid | uniqueid | calldate | src | dst | recordingfile | billsec | duration |
