Question

是Zend_Db_Select的where（）方法，当包含可选值时，和Zend_Db_Adapte的quoteInto（）方法基本相同，只是转义SQL？

换句话说，这两段引语是否相同且同样安全？

$select->where($this->getAdapter()->quoteInto('id = ?', 3));

$select->where(id = ?, 3);

谢谢！

Zend_Db_Select :: _ where（）使用Zend_Db_Abstract :: quoteInto（）引用您在汇编sql字符串时指定为Zend_Db_Select :: where（）中的第二个参数的值。

从Zend_Db_Select的第983行开始：

/**
 * Internal function for creating the where clause
 *
 * @param string   $condition
 * @param mixed    $value  optional
 * @param string   $type   optional
 * @param boolean  $bool  true = AND, false = OR
 * @return string  clause
 */
protected function _where($condition, $value = null, $type = null, $bool = true)
{
    if (count($this->_parts[self::UNION])) {
        require_once 'Zend/Db/Select/Exception.php';
        throw new Zend_Db_Select_Exception("Invalid use of where clause with " . self::SQL_UNION);
    }

    if ($value !== null) {
        $condition = $this->_adapter->quoteInto($condition, $value, $type);
    }

    $cond = "";
    if ($this->_parts[self::WHERE]) {
        if ($bool === true) {
            $cond = self::SQL_AND . ' ';
        } else {
            $cond = self::SQL_OR . ' ';
        }
    }

    return $cond . "($condition)";
}

据我了解，这已经在哪里指明它将是多余的。

Zend_Db_Select where（）和Zend_Db_Adapter quoteInto（）
