的Joomla 2.5與LEFT刪除查詢JOIN

Question

我試着去實現與LEFT刪除代碼加入的Joomla 2.5：

$cid = JRequest::getVar('cid', array(), 'post', 'array'); 

$query = $db->getQuery(true); 

$query->delete($db->quoteName('table1').' AS t1'); 

$query->leftJoin($db->quoteName('table2'). 
' AS t2 ON t2.table_1_id = t1.id '); 

$query->where(array('t1.id IN ('. implode(',', $cid).')')); 

$db->setQuery($query); 

try { 
    $db->query(); 
} catch (Exception $e) { 
    echo $e->getMessage(); 
} 

我得到的是：

DELETE FROM `table1` AS t1 
LEFT JOIN `table2` AS t2 ON t2.table_1_id = t1.id 
WHERE t1.id IN (48) 

這個SQL查詢是不正確。我需要的是：

DELETE t1.*,t2.* FROM `table1` AS t1 
LEFT JOIN `table2` AS t2 ON t2.table_1_id = t1.id 
WHERE t1.id IN (48) 

所以，我應該怎麼改變的Joomla查詢以獲得正確的SQL查詢？有任何想法嗎？

我一直在Joomla工作很長時間了。根據我的Joomla知識，你無法完成你想要做的事$query->delete()。由於您的查詢有點棘手，因此可以使用下面的方法執行。

$db = JFactory::getDBO(); 
$query = "DELETE t1.*,t2.* FROM `table1` AS t1 
LEFT JOIN `table2` AS t2 ON t2.table_1_id = t1.id 
WHERE t1.id IN (48)"; // you can replace the line with array('t1.id IN ('. implode(',', $cid).')') 
$db->setQuery($query); 
$db->query();
