问题描述

| 目前，我有查询来输出一天的平均速度和最大速度作为我要优化的查询，像这样 
SELECT V_VEHICLEID,V_LICENSENO,(SELECT ROUND(AVG(WP_SPEED),2) FROM WAYPOINTS WHERE DAY(WP_DATETIME) = 1 AND WP_VEHICLEID = V_VEHICLEID) AS AVG1,2) FROM WAYPOINTS WHERE DAY(WP_DATETIME) = 2 AND

FROM VEHICLES
WHERE V_USER = \'tc\'
已经尝试过此查询，但我希望结果表（以html形式）看起来像上面的查询 
SELECT WP_VEHICLEID AS VEHICLE,V_LICENSENO AS REGNO,DATE(WP_DATETIME) AS SUM_DATE,ROUND(AVG(WP_SPEED),2) AS AVG_SPEED,ROUND(MAX(WP_SPEED),2) AS MAX_SPEED
FROM WAYPOINTS,VEHICLES
WHERE MONTH(WP_DATETIME) = 6
AND WP_ODOMETER  0
AND V_VEHICLEID = WP_VEHICLEID
AND V_USER = \'tc\'
GROUP BY WP_VEHICLEID,DATE(WP_DATETIME)
ORDER BY WP_VEHICLEID,WP_DATETIME
结果表 
========================================================
VEHICLE|     1     |     2     |     3     |     4     |
       -------------------------------------------------
       | AVG | MAX | AVG | MAX | AVG | MAX | AVG | MAX |
========================================================
CAR A  | 10  | 30  |  90 | 160 | .......................
CAR B  | 50  | 90  |  0  | 0   | .......................
CAR C  | 15  | 20  |  10 | 10  | .......................
========================================================
有什么办法吗？
