Mr. Huang,

Seems to me that your GROUP BY line should read:

GROUP BY ltb.v_id, vtb.equip_attr[1], vtb.equip_attr[3],
vtb.equip_attr[4]

Or am I missing the point?

>        vtb.equip_attr[1] AS year,
>        vtb.equip_attr[3] AS model,
>        vtb.equip_attr[4] AS type
> FROM log_tb ltb, vehicle_tb vtb
> WHERE ltb.v_id=vtb.equip_id
> GROUP BY ltb.v_id
> ORDER BY year;
