我正在执行我的 SQL 查询，有时更新结果真的很奇怪。它正在更新box_status 字段为空（box_status字段为枚举类型值即可A,L,R）。此更新查询循环运行。

update box_master 
    set box_to_show = '0', 
        box_status = 'L' 
where box_id = '{$param_arr['box_id']}' 
and box_status in ( 'A','L')

我被卡住了，这个问题已经过去了 2 天，没有得到任何线索或解决方案。

从评论转移的代码

PHP

$update_sql = ""; 
$update_sql = "update box_master set box_to_show = '0', box_status = 'L' where box_id = '{$param_arr['box_id']}' and box_status in ( 'A','L') "; 

$result = mysql_query ( $update_sql, $link ); 

$update_sql = ""; 

if (mysql_affected_rows ( $link ) > 0) { 
   $param_arr ['remarks'] = " box_stock is 1 or 2 and market id is not 2, so changing box to show to 0 and box_status to L from {$param_arr['box_status']}"; 
}
