PDOStatement对象::执行（）：SQLSTATE [HY093]：无效的参数编号：绑定变量的数量并不至于我可以告诉变量的数量做匹配令牌的数量相匹配的令牌

Question

$sql = 'INSERT INTO `' . $table_name . '` ' 
      . '(`day`, `campaign_name`, `campaign_id`, `views`, `CPM`, `cost`, `currency`, `cost_EUR`) VALUES ' 
      . '(:day, :campaign_name, :campaign_id, :views, :CPM, :cost, :currency, :cost_EUR)'; 

$this->_dbi->execute($sql, array(
      ':day'  => $day, 
      ':campaign_name'  => $campaignName, 
      ':campaign_id' => $campaignID, 
      ':views'   => $views, 
      ':CPM'  => $cpm, 
      ':cost'  => $cost_EUR, 
      ':currency'  => 'EUR', 
      ':cost_EUR' => $cost_EUR 
)); 

的数量。 我只是无法弄清楚这里的错误。

Answer 1

您只需要将数组传递给execute方法。所以，你的更新的代码应该是这样的：

$sql = 'INSERT INTO `' . $table_name . '` ' 
      . '(`day`, `campaign_name`, `campaign_id`, `views`, `CPM`, `cost`, `currency`, `cost_EUR`) VALUES ' 
      . '(:day, :campaign_name, :campaign_id, :views, :CPM, :cost, :currency, :cost_EUR)'; 
$sth = $this->_dbi->prepare($sql);  
$sth->execute(array(
      ':day'  => $day, 
      ':campaign_name'  => $campaignName, 
      ':campaign_id' => $campaignID, 
      ':views'   => $views, 
      ':CPM'  => $cpm, 
      ':cost'  => $cost_EUR, 
      ':currency'  => 'EUR', 
      ':cost_EUR' => $cost_EUR 
));

PDOStatement对象::执行 - 执行一个准备好的声明

使用：公共BOOL PDOStatement对象::执行（[array $ input_parameters]）

下面是从th e文档：

<?php 
/* Execute a prepared statement by passing an array of insert values */ 
$calories = 150; 
$colour = 'red'; 
$sth = $dbh->prepare('SELECT name, colour, calories 
    FROM fruit 
    WHERE calories < :calories AND colour = :colour'); 
$sth->execute(array(':calories' => $calories, ':colour' => $colour));
