に奇妙な問題がありmysql_fetch_array( $result , MYSQL_BOTH )
ます。これが問題の再現方法です。
- を使用するクエリ文字列を実行します
LEFT JOIN
。GROUP BY
select *,
(A1.total - A2.borrow_total) as remain_total
from ( select Min(sample_created_date) as created_date,
sample_model,
sample_ncc,
count(*) as total ,
sample_sort
from tb_sample
where 1=1
AND sample_kho IN ( 'hanoi','tm_hanoi' )
group by sample_model, sample_sort, sample_ncc
) A1 left join
( select sample_model as sample_model1,
count(*) as borrow_total,
sample_ncc
from tb_sample B1 left join tb_sample_ticket B2
on B1.sample_borrow_status = B2.ticket_id
where 1=1
and ticket_bo_phan_duyet = 'finish'
and ticket_status_duyet = '1'
AND sample_kho IN ( 'hanoi','tm_hanoi' )
group by sample_model, sample_ncc
) A2 on A1.sample_model = A2.sample_model1
AND A1.sample_ncc = A2.sample_ncc left join tb_product_sort A3
on A1.sample_sort = A3.sort_code
where 1=1
order by created_date DESC
LIMIT 0, 30
実装
mysql_fetch_array( $result , MYSQL_BOTH )
:$rw = mysql_fetch_array( $result , MYSQL_BOTH );
の表示値
$rw
:echo $rw['sample_cc'];
しかし、何もありません。次に、試してみprint_r( $rw )
ます。結果については以下を参照してください。
Array
(
[0] => 2013-06-13 04:10:39
[created_date] => 2013-06-13 04:10:39
[1] => 3G
[sample_model] => 3G
**[2] => Gmobile
[sample_ncc] =>**
[3] => 1
[total] => 1
[4] => SIM
[sample_sort] => SIM
);
私はそれを参照して$Rw[2] = 3G
ください$rw['sample_ncc'] is null
。
これは奇妙な問題です。私がそれを解決するのを手伝ってください。
