quoteInto（）和Zend_Db的生成错误

Question

我已经写了一段代码，看是否记录已在数据库中，该代码是这样的：

$sql = $dbRead->quoteInto('SELECT email FROM betaEmail WHERE validate = ?'.$_POST['validate']); 

和连接，我使用Zend_Db_Adapter_Pdo_Mysql。产生以下错误，我应该如何解决它？任何解决方案

Warning: Missing argument 2 for Zend_Db_Adapter_Abstract::quoteInto(), called in 
/Applications/MAMP/htdocs/myform/user_registration.php on line 16 and defined in 
/Users/payam/php_library/ZendFramework-1.11.8/library/Zend/Db/Adapter/Abstract.php 
on line 927
