Question

我正在使用预准备语句来插入数据。我得到'Invalid parameter number: number of bound variables does not match number of tokens.'我试图抛弃准备好的声明，但我无法发现不匹配。有没有办法弄清楚不匹配。

  $i = 0 ; $j = 0  ; $k = 0 ; $l = 0 ;  $str = "" ; $region_str = '' ; 
  $occasion_str = '' ; $flavor_str = '' ; 


       foreach($result->WINES->WINE as $w) 
                {
                if($i == 0) 
                $str = "(:wineid$i,:acctid$i,:brand$i,:varietal$i,:descr$i,:prop$i,:color$i,:case$i,:url$i)" ;
                else
                $str .= ", (:wineid$i,:acctid$i,:brand$i,:varietal$i,:descr$i,:prop$i,:color$i,:case$i,:url$i)" ;   

                foreach($w->REGIONS->REGION as $region) 
                                               {
                                                   if($j == 0)
                                                    $region_str = "(:rwineid$i,:region$j)" ;
