选择分组查询

Question

我有以下查询，它为每个'SENDER_REFERENCE_NB'返回两个项目，一个是MESSAGE_STATUS是'（接收）'，另一个是MESSAGE_STATUS'匹配'。两者都包含CREATE_TM

select MESSAGE_ID, CREATE_TM, MESSAGE_STATUS
from TMS_MESSAGE_AUDIT_LOG
where message_id in (select message_id from tms_message
                     WHERE SENDER_REFERENCE_NB like '150703%')
  and MESSAGE_STATUS in ('(Receive)', 'Matched');

我想要实现的是每个SENDER_REFERENCE_NB，我看到（'Receive'）状态＆amp;与此条目相关联的CREATE_TM和“匹配”状态以及CREATE_TM关联，全部在一行上。

Answer 1

做出一些假设，这是我的答案：

Select L1.MESSAGE_ID, L1.CREATE_TM, L1.MESSAGE_STATUS, 
       L2.MESSAGE_ID, L2.CREATE_TM, L2.MESSAGE_STATUS
from TMS_MESSAGE_AUDIT_LOG AS L1
INNER JOIN TMS_MESSAGE_AUDIT_LOG AS L2
ON L1.MESSAGE_STATUS = '(Receive)'
AND L1.SENDER_REFERENCE_NB like '150703%'
AND L2.SENDER_REFERENCE_NB like '150703%'
AND L2.MESSAGE_STATUS = 'Matched'
