在Zend中执行SQL查询时出现问题？

Question

我正在执行的SQL查询中的Zend这样的事情，它是工作：

$front = Zend_Controller_Front::getInstance(); 
$bootstrap = $front->getParam('bootstrap'); 
$resource = $bootstrap->getPluginResource('db'); 
$dbAdapter = $resource->getDbAdapter(); 
$statement = $dbAdapter->query("SELECT * from tablename"); 
$results = $statement->fetchAll(); 

当时我的application.ini是这样的：

resources.db.adapter = "Mysqli" 
resources.db.params.host = "localhost" 
resources.db.params.username = "username" 
resources.db.params.password = "password" 
resources.db.params.dbname = "dbname" 

问题：

现在我将我的application.ini更改为：

resources.multidb.local.adapter = "Mysqli" 
resources.multidb.local.host = "localhost" 
resources.multidb.local.username = "username" 
resources.multidb.local.password = "passwod" 
resources.multidb.local.dbname = "dbname" 
resources.multidb.local.default = true 

现在上面的Zend代码生成以下错误：

Fatal error: Call to a member function getDbAdapter() on a non-object in Mapper.php on line 297 

如何解决根据新的application.ini设置我的代码？

感谢

Answer 1

要检索默认的数据库适配器使用下面的代码：

$bootstrap = Zend_Controller_Front::getInstance()->getParam('bootstrap'); 
$resource = $bootstrap->getPluginResource('multidb'); 
$db = $resource->getDb(); 

Answer 2

下面的代码是为我工作与multidb配置的application.ini

$bootstrap = Zend_Controller_Front::getInstance()->getParam('bootstrap'); 
$resource = $bootstrap->getPluginResource('multidb'); 
$db = $resource->getDb(); 
$statement = $db->query("SELECT * from tablename"); 
$results = $statement->fetchAll();
