当扩展 Zend_Db_Table_Abstract 创建一个连接时,它会使 MySQL 崩溃
我想了解为什么它可以完美地工作而没有问题。
$this->db = Zend_Db_Table_Abstract::getDefaultAdapter();
public function getMessages()
{
$select = $this->db->select();
$select
->from('Mail_Text', '*')
->join(
array('Mail' => 'Mail'),
'Mail.id = Mail_Text.parent_id', '*'
);
return $this->db->fetchAll($select);
}
现在,如果我通过扩展 Zend_Db_Table_Abstract 来做到这一点,
class Mail_Model_Text extends Zend_Db_Table_Abstract
{
protected $_name = 'Mail_Text';
public function fetchMessges(){
$select = $this->select();
$select->setIntegrityCheck(false)
->from($this->_name, '*')
->join(
array('Mail' => 'Mail'),
'Mail.id = Mail_Text.parent_id', '*'
);
return $this->fetchAll($select);
}
}
这会导致 MySql 崩溃,我想将代码分开,但我可以连接这些表。所有单一选择和更新查询都工作完美。我在网上进行了研究,似乎无法找到这个难题的解决方案。任何对他的帮助都会非常感谢。
I want to understand why this works perfect with out a problem.
$this->db = Zend_Db_Table_Abstract::getDefaultAdapter();
public function getMessages()
{
$select = $this->db->select();
$select
->from('Mail_Text', '*')
->join(
array('Mail' => 'Mail'),
'Mail.id = Mail_Text.parent_id', '*'
);
return $this->db->fetchAll($select);
}
Now if I do this by extending Zend_Db_Table_Abstract
class Mail_Model_Text extends Zend_Db_Table_Abstract
{
protected $_name = 'Mail_Text';
public function fetchMessges(){
$select = $this->select();
$select->setIntegrityCheck(false)
->from($this->_name, '*')
->join(
array('Mail' => 'Mail'),
'Mail.id = Mail_Text.parent_id', '*'
);
return $this->fetchAll($select);
}
}
This crashes MySql I wanted to keep the code separate but I can join theses tables. All the Single select and updates query's work perfect. I have research all over the net and can't seem to find the solution to this puzzle. Any Help to his would be great Thanks in advance.

您不需要 from() 语句或需要将表别名为相同名称:
class Mail_Model_Text extends Zend_Db_Table_Abstract
{
受保护的$_name = 'Mail_Text';
另外,请确保
您已正确对表建立索引。
You don't need the from() statement or need to alias the table to the same name:
class Mail_Model_Text extends Zend_Db_Table_Abstract
{
protected $_name = 'Mail_Text';
}
Also, ensure that you have correctly indexed your tables.
