不是在同一個表中的條款需要時間在oracle中

Question

查詢是如..

select deviceid,devicename,totalbytes,'Others' as protocolgroup from (
    select d.deviceid,d.name as devicename,sum(bytes) as totalbytes from tblmainallowedtraffic_5min b,tbldevice d 
    WHERE ( B.APPID IN ('C070100126-VW717U','C018600068-GEF3O6','C045701665-9B6S1A','C026100710-36NPQE','C016801597-V1Z8IM')) 
    and proto_group not in (select proto_group from (select proto_group,sum(bytes) from 
    TBLMAINALLOWEDTRAFFIC_5MIN B WHERE ( B.APPID IN ('C070100126-VW717U','C018600068-GEF3O6','C045701665-9B6S1A', 
    'C026100710-36NPQE','C016801597-V1Z8IM')) AND "5mintime" >='04-APR-12 12.00.00.000000 AM' AND 
    "5mintime" <='04-APR-12 11.59.59.000000 PM' group by proto_group order by sum(bytes) desc) WHERE ROWNUM <=5) 
    AND B.APPID=D.APPID AND "5mintime" >='04-APR-12 12.00.00.000000 AM' AND "5mintime" <='04-APR-12 11.59.59.000000 PM' 
    GROUP BY D.APPID,D.DEVICEID,D.NAME) 
    order by protocolgroup desc, totalbytes desc 

在解釋計劃它說..

3 - 過濾器（NOT EXISTS（不可行））

如果更改與靜態內部查詢結果中的上述查詢，輸出來更快：

select deviceid,devicename,totalbytes,'Others' as protocolgroup from (
    select d.deviceid,d.name as devicename,sum(bytes) as totalbytes from tblmainallowedtraffic_5min b,tbldevice d 
    WHERE ( B.APPID IN ('C070100126-VW717U','C018600068-GEF3O6','C045701665-9B6S1A','C026100710-36NPQE','C016801597-V1Z8IM')) 
    and proto_group not in ('POP3','HTTP Request Response','Web','GET HTTP DATA MORE THAN 976 KB','SMTP') 
    AND B.APPID=D.APPID AND "5mintime" >='04-APR-12 12.00.00.000000 AM' AND "5mintime" <='04-APR-12 11.59.59.000000 PM' 
    GROUP BY D.APPID,D.DEVICEID,D.NAME) 
    order by protocolgroup desc, totalbytes desc 

所以不存在子句是在同一個表上創建的問題..
你可以給這個想法嗎？

嘗試做一個反連接：

SELECT deviceid, 
    devicename, 
    totalbytes, 
    'Others' AS protocolgroup 
FROM 
    (SELECT d.deviceid, 
    d.name  AS devicename, 
    SUM(bytes) AS totalbytes 
    FROM tblmainallowedtraffic_5min b, 
    tbldevice d 
    LEFT OUTER JOIN 
    (SELECT proto_group 
    FROM 
     (SELECT proto_group, 
     SUM(bytes) 
     FROM TBLMAINALLOWEDTRAFFIC_5MIN B 
     WHERE (B.APPID IN ('C070100126-VW717U','C018600068-GEF3O6','C045701665-9B6S1A', 'C026100710-36NPQE','C016801597-V1Z8IM')) 
     AND "5mintime" >='04-APR-12 12.00.00.000000 AM' 
     AND "5mintime" <='04-APR-12 11.59.59.000000 PM' 
     GROUP BY proto_group 
     ORDER BY SUM(bytes) DESC 
    ) 
    WHERE ROWNUM <=5 
    ) e ON b.proto_group = e.proto_group 
    WHERE (B.APPID  IN ('C070100126-VW717U','C018600068-GEF3O6','C045701665-9B6S1A','C026100710-36NPQE','C016801597-V1Z8IM')) 
    AND e.proto_group is null 
    AND B.APPID  =D.APPID 
    AND "5mintime" >='04-APR-12 12.00.00.000000 AM' 
    AND "5mintime" <='04-APR-12 11.59.59.000000 PM' 
    GROUP BY D.APPID, 
    D.DEVICEID, 
    D.NAME 
) 
ORDER BY protocolgroup DESC, 
    totalbytes DESC
