MySqli查詢在phpmyadmin中有效，在php腳本中無效

Question

我有一個問題。

我嘗試做簡單的查詢：

        $this->db->query("  INSERT INTO prognosis(stamp,day_ep,day_ep_sum,day_time,day_time_sum,week_ep,week_ep_sum,week_time,week_time_sum,month_ep,month_ep_sum,month_time,month_ep_sum,year_ep,year_ep_sum,year_time,year_time_sum)
                        VALUES('$stamp',$today_ep,$today_ep_sum,$today_time,$today_time_sum,$week_ep,$week_ep_sum,$week_time,$week_time_sum,$month_ep,$month_ep_sum,$month_time,$month_time_sum,$year_ep,$year_ep_sum,$year_time,$year_time_sum)
                    ");

...並且表仍然為空，因此我使用echo將帶有值的完整查詢打印到html文件（元字符集= utf-8）：

INSERT INTO prognosis ( stamp, day_ep, day_ep_sum, day_time, day_time_sum, week_ep, week_ep_sum, week_time, week_time_sum, month_ep, month_ep_sum, month_time, month_time_sum, year_ep, year_ep_sum, year_time, year_time_sum ) VALUES ( '2016-01-09', 7, 5544, 318, 210948, 53, 5547, 2240, 211040, 289, 5744, 12844, 219835, 3366, 8822, 151232, 358223 )

ctrl + C，ctrl + V到phpmyadmin，並且表接受該查詢（為什么？）

        [Key] => 
        [Default] => 
        [Extra] => 
    )

）

我注意到了一件有趣的事情：當我試圖找到這種行為的原因時，我試圖執行較短的查詢：

        $this->db->query("  INSERT INTO prognosis(stamp,year_ep,year_ep_sum,year_time,year_time_sum)
                        VALUES('$stamp',$year_ep,$year_ep_sum,$year_time,$year_time_sum)

並且它工作正常，但我必須執行完整版本的查詢。

請檢查phpmyadmin中的Collaction字段，如果已選擇，則設置為空白。
