如何找到列中的2行之間的時間差

Question

嗨當​​我使用此查詢它給了我2列，每一行都會有一個請求和一個響應。我如何在幾秒鐘內獲取這兩者之間的時間差。

select M.MSG_DESC, M.Msg_Ts from INTLOG.ESB_MSG_L M,INTLOG.ESB_PAYLOAD_L P 
where M.MSG_ID = P.MSG_ID 
And M.Msg_Ts >= Timestamp'2014-02-16 00:00:00' 
And M.Msg_Ts <= Timestamp'2014-02-17 12:00:00' 
And M.Msg_ID IN ('90808','67678','534534') 
ORDER by M.MSG_TS,p.payload_corl_id desc;

select M.MSG_DESC 
    , M.Msg_Ts 
    ,TIMESTAMPDIFF(SECOND, M.MSG_DESC, M.Msg_Ts) 
from INTLOG.ESB_MSG_L M INNER JOIN INTLOG.ESB_PAYLOAD_L P 
ON M.MSG_ID = P.MSG_ID 
WHERE 
    M.Msg_Ts >= Timestamp'2014-02-16 00:00:00' 
And M.Msg_Ts <= Timestamp'2014-02-17 12:00:00' 
And M.Msg_ID IN ('90808','67678','534534') 
ORDER by M.MSG_TS,p.payload_corl_id desc;
