Bruno, i don't understand how this would help my
situation, but i think the problem is that i poorly
communicated the original problem. ;-)
however, i am very close to what i want... but not
quite there.
i use this query...
SELECT t_inspect_result.inspect_result,
t_inspect.inspect_id
FROM t_inspect_result, t_inspect, t_inspect_area,
t_serial_number,
t_link_contract_number_job_number, t_job_number,
t_product
WHERE t_inspect.inspect_area_id =
t_inspect_area.inspect_area_id
AND t_inspect.serial_number_id =
t_serial_number.serial_number_id
AND t_serial_number.link_contract_number_job_number_id
=
t_link_contract_number_job_number.link_contract_number_job_number_id
AND t_link_contract_number_job_number.job_number_id =
t_job_number.job_number_id
AND t_product.product_id =
t_job_number.product_id
AND t_inspect.inspect_id =
t_inspect_result.inspect_id
AND t_inspect.serial_number_id = '184'
GROUP BY t_inspect_result.inspect_timestamp,
t_inspect_result.inspect_result, t_inspect.inspect_id
ORDER BY t_inspect_result.inspect_timestamp desc
to get these results...
Row / inspect_result / inspect_id
1 / t / 107
2 / t / 106
3 / f / 100
4 / t / 100
i can't figure out how to group by
t_inspect.inspect_id and limit the query to one result
per inspect_id.
iow, i want to see...
Row / inspect_result / inspect_id
1 / t / 107
2 / t / 106
3 / f / 100
when i apply a limit 1, it returns a single result,
not a single result per inspect_id. i tried (), but
to no avail.
any guidance is, as always, much appreciated.
