我有下面提到的数据。我希望得到开始消息的min和相应的成功消息。如果没有启动或成功消息，则它应显示为null。

我正在尝试将start_timestamp的Min与下一个与id1和jobid相对应的success_timestamp的Min结合起来。如果给定的id1和jobid有一个启动消息列表并且没有成功消息，那么它应该显示NULL并且反之亦然。使用WITH子句尝试使用临时表，也使用自连接方法。下面是我的查询，但WITH子句查询返回表中整体数据的MIN。
使用的查询：
WITH DATA AS
(SELECT MIN(smt.column13) timestamp_for_success_message
FROM success_table1 smt, start_table2 b
WHERE
(SMT.id1 = b.id1)
AND (SMT.jobid = b.jobid)
AND (SMT.timestamp_for_success_message_recieved >= b.timestamp_for_start_message_recieved)
)
SELECT distinct a.timestamp_for_success_message_recieved,
b.timestamp_for_start_message_recieved,
b.id1,
b.jobid
FROM data a,
start_table2 b
order by b.timestamp_start_message_recieved, a.timestamp_for_success_message_recieved, b.jobid, b.id1;
答案 0 :(得分：1)
我能得到的最近的是：你会注意到我的下面的查询显示了一些没有结束的开始...你不解释如何处理这些。此外，我的查询链接不同的开始和结束。你说
“开始消息的最小值和start_secs与成功的最小值配对 消息“
我在下面做了，它链接：“264与4280”，而不是“165与4280”，如你所示。由于262与290配对，这意味着264现在是与MIN成功匹配的MIN，4280。 如果您可以进一步澄清您的要求，我可以调整查询。

试图了解您之后的情况，您似乎想要完全忽略所列时间的SECONDS组件？如果它们匹配，则将结果时间视为重复（即9：21 = 9:31 ..从9:00 = 9:00）。
如果是这样的话，那么这个查询会返回你的样本（除了你的错字＃34; 11：45：15＆＃34;显示为＆＃34; 11：45：25＆＃34; ;）
