额，不知道标题是否合理，情况是这样的，我想实现一个类似滑动订单的查询，就是查看每分钟一共收到了多少请求。该表比较大

select count(*) from gwserverperfdatas;

'15636855'

我想只查询其中一部分

CREATE View tmpGw as select * from gwserverperfdatas where OccurTime>=utc_date();

select time(a.OccurTime) as endtime,

time (b.OccurTime) as beginTime,

max(c.RecvReqCount)-min(c.RecvReqCount)

from tmpGw a

inner join tmpGw b

on date_add(a.OccurTime, INTERVAL 1 MINUTE) = b.OccurTime

inner join tmpGw c

on c.OccurTime between a.OccurTime and b.OccurTime

group by a.OccurTime,b.OccurTime

不过不管是使用临时表还是使用视图都会提示如下错误：

13:08:24 select time(a.OccurTime) as endtime, time (b.OccurTime) as beginTime, max(c.RecvReqCount)-min(c.RecvReqCount) from tmpGw a inner join tmpGw b on date_add(a.OccurTime, INTERVAL 1 MINUTE) = b.OccurTime inner join tmpGw c on c.OccurTime between a.OccurTime and b.OccurTime group by a.OccurTime,b.OccurTime LIMIT 0, 1000 Error Code: 1137. Can't reopen table: 'a' 0.000 sec

网络上搜了一下提示是说在一个查询中视图和临时表只能被引用一次，如果我不用临时表的话直接再最后加一个where，或者每一个from都加一个子查询语句都没跑完成过。

另外如果我想查询那一分钟请求数最大如何实现呢？将这个查询作为子查询吗？

另外在orm中实现滑动订单容易吗？

补充一些信息：

子查询只限于当天

select count(*) from gwserverperfdatas where gwserverperfdatas.OccurTime >= utc_date()

'661926'

describe gwserverperfdatas;

@冰灵果 提供了一个很简单的方案，看了让人眼前一亮，不过以上只是求每笔数据一分钟内的数量，想请问有没有简单的办法计算每三个月的订单数量，即

select time(a.OccurTime) as endtime,

time (b.OccurTime) as beginTime,

max(c.RecvReqCount)-min(c.RecvReqCount)

from tmpGw a

inner join tmpGw b

on date_add(a.OccurTime, INTERVAL 3 MONTH) = b.OccurTime

inner join tmpGw c

on c.OccurTime between a.OccurTime and b.OccurTime

group by a.OccurTime,b.OccurTime

请问在Hibernate这种ORM中是否能实现呢？只能走SQL语句吗？
