Question

如何实现“插入忽略”？使用kohana orm添加多条记录时，如果使用下面的代码，数据库中可能已经存在少量记录，则会拒绝添加所有100条记录。

$query = DB::insert('tablename', array('column1', 'column2','column3'));

 foreach ($data as $d) {
    $query->values($d);
 }
 try {
    $result = $query->execute();
 } catch ( Database_Exception $e ) {   
    echo $e->getMessage();
 }

更新这是我如何做到这一点，我必须插入多个记录，

$Xtransactions = "INSERT IGNORE INTO `tablename` (`tid`, `tdate`, `appid`, 
                                              `userid`, `user_ip`) VALUES";

foreach ($objSas->trecord as $trow) {                      
  $Xtransactions .= "(".$trow->tid.",'". 
  date('Y-m-d H:i:s', strtotime($trow->tdate))."',".
  $trow->userid.",".
  $trow->Xnumber.",'".
  $trow->ip."'),";
}
    $Xtransactions  = substr($Xtransactions , 0, -1);                         
 try {                      
      DB::query(Database::INSERT, $Xtransactions )->execute();
 } catch ( Database_Exception $e ) {   
      echo $e->getMessage();
 }

Answer 1

使用查询构建器，这是不可能的，尝试编写原始查询。

DB::query(Database::INSERT, 'INSERT IGNORE INTO table VALUES (...)')->execute();

Answer 2

我通常在静态助手类中收集此类修改，例如

<?php defined('SYSPATH') or die('No direct script access.');

class Helper_DB_Query{
/**
 * @param Database_Query_Builder_Insert $insert query thant need to be converted
 * @return Database_Query converted query
 */
    public static function insert_to_insert_ignore( Database_Query_Builder_Insert $insert ){

        $insert = (string) $insert;

        $query = preg_replace("/^INSERT(.*)$/", "INSERT IGNORE $1", $insert);

        return DB::query(Database::INSERT, $query);

    }



}
