我有一个queue_log表，其中包含单个调用记录的多个记录，并且对于单个调用行数重复了唯一列call_id。
我有以下查询。
select case when verb="did" then data1 end as did,
case when verb='CONNECT' then "Answered" else "Missed" end as status,
queue,verb,
case when verb in ('connect') then agent end as agent
from queue_log
where created between '2019-09-01' and '2019-09-09'
group by call_id
having verb in ('did','connect','enterqueue','completecaller','completeagent','abandon','exitwithtimeout');
让我们再解释一下。 如果我在queue_log中有一个调用，它有一个记录，其中verb=did，第二个verb=connect，然后第三个记录，动词在('completecaller','completeagent')，并且所有行的call_id都相同。
如果任何行中有动词 connect，则此调用将被应答，否则放弃。
以上查询返回所有放弃调用。同时也有接听电话。
以下是示例数据。

您的示例数据问题和预期结果与我不符。我的猜测是，总是有 1 个连接，但可能有多个连接或没有连接。稍微修改您的示例数据
drop table if exists t;
create table t

data4 varchar(20), data5 varchar(20), `partition` varchar(20), created datetime);
