的mysqli和multi_query不工作

Question

<?php 

$mysqli=mysqli_connect("localhost","root","","politicalforum"); 

$query="SELECT query_title FROM administrator"; 
    $query.="SELECT thread_id FROM threads"; 

if($mysqli->multi_query($query)) 
{ 
    do 
    { 

     if($result=$mysqli->store_result()) 
     { 
      while($row=$result->fetch_row()) 
      { 
       printf("%s\n",$row[0]); 
      } 
      $result->free(); 
     } 

     if($mysqli->more_results()) 
     { 
      print("-------------------------------"); 
     } 
    }while($mysql->next_result()); 
} 


$mysqli->close();

它不工作..它不進入第一個，如果條件標識，如果它是一個multiquery .. 我有其他的問題，..why是multi_query()是有用..，

UPDATE：

嚴格的標準：mysqli的:: next_result（）[mysqli.next-結果]：有 沒有下一個結果集。請叫 mysqli_more_results（）/ mysqli的:: more_results（）來檢查是否調用 此功能/方法C：\ XAMPP \ htdocs中\ PoliticalForum2 \ test.php的上 線42

解決：

<?php 

$mysqli=mysqli_connect("localhost","root","","politicalforum"); 

$query="SELECT query_title FROM administrator;"; 
    $query.="SELECT thread_id FROM threads;"; 

if($mysqli->multi_query($query)) 
{ 
    do 
    { 

     if($result=$mysqli->store_result()) 
     { 
      while($row=$result->fetch_row()) 
      { 
       printf("%s<br/>",$row[0]); 
      } 
      $result->free(); 
     } 

     if($mysqli->more_results()) 
     { 
      print("-------------------------------<br/>"); 
     } 
     else 
     { 
      echo '<br/>'; 
     } 
    }while($mysqli->more_results() && $mysqli->next_result()); 
} 


$mysqli->close();

Answer 1

您在第一次查詢的結尾需要一個分號。

$query="SELECT query_title FROM administrator;"; 
$query.="SELECT thread_id FROM threads"; 

mysqli::multi_query

Answer 2

爲什麼你得到這樣的警告的原因，完全是因爲你用做... while循環運行命令塊之後計算該條件。因此，當沒有更多結果時，循環的內容會再運行一次，產生該警告。

使用一段時間（$ mysql-> next_result（））... DO循環應該解決這個問題。 （在一般注意事項：使用後測試循環像你這樣是在數據庫編程相當少見）

如果代碼是詩，我想是莎士比亞！

我得到了同樣的答案。

請在下面找到我的功能。

public function executeStoredProcedureMulti($strQuery) 
{ 
    $yml = sfYaml::load(sfConfig::get('sf_config_dir').'/databases.yml'); 
    $params = $yml['all']['doctrine']['param']; 
    $dsnName = $params['dsn']; 
    $arrDsn = explode(";",$dsnName); 
    $hostName = explode("=",$arrDsn[0])[1]; 
    $schemaName = explode("=",$arrDsn[1])[1]; 
    $this->dbconn = mysqli_connect($hostName, $params['username'], $params['password'], $schemaName); 

    //return if connection was created successfully 
    if($this->dbconn) 
    { 
     mysqli_set_charset($this->dbconn,"utf8"); 
     //return true; 
    } 
    else 
    { 
     $this->nErrorNumber = mysqli_connect_errno(); 
     $this->strErrorDesc = mysqli_connect_error(); 
     return false; 
    } 


    //check if connection exists 
    if($this->dbconn) 
    { 

     /* close connection */ 
     //execute the query 
     if($this->dbconn->multi_query($strQuery)) 
     { 
      //create table array in dataset object 
      $dataSet = array(); 
      do { 
       //store first result set 
       if ($result = $this->dbconn->store_result()) 
       { 
        //create data table passing it the column data 
        $dataTable = new CDataTable($result->fetch_fields()); 

        //parse through each row 
        while ($row = $result->fetch_row()) 
        { 
         $dataTable->AddRow($row); 
        } 
        $result->free(); 
        $dataSet[] = $dataTable; 
       } 
       if (!$this->dbconn->more_results()) { 
        break; 
       } 
      } while ($this->dbconn->next_result()); 
      $this->dbconn->close(); 
      //return the complete dataset 
      return $dataSet; 
     } 
     else//save the error to member variables 
     { 
      $this->nErrorNumber = $this->dbconn->errno; 
      $this->strErrorDesc = $this->dbconn->error; 
     } 
    } 
    return false; 
} 

這是工作需要創建一個類CTableData。請製作一個，它會很好地工作 。

你能解決這個問題是這樣的：

if ($res) { 

    do { 
     $mycon->next_result(); //// instead of putting it in a while, put it here 

     if ($result = $mycon->store_result()) { 

      while ($row = $result->fetch_row()) { 

       foreach ($row as $cell) 

        $flag = $cell; 
      } 

      ///$result->close(); 
     } 
     $sale=$sale+1; 

    } while ($sale > 2); 
}
