Hey,
If you use group then except aggreate functions(count,sum..)
other items in your select list should be in your group list also.

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?

Hi, I have the following SQL:
SELECT ltb.v_id,
count(ltb.v_id) AS num_of_times_borrowed,
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;
