我收到一个查询错误,我的问题是:我可以链接连接吗?zf1:链接加入
我的第一次连接是到主表,但我的第二次连接是连接到主表的表。这是查询:
$query = $this->getDbTable()->select()
->from(array('ca' => 'contracts_allotment'),
array('id',
'contracts_rooms_id' => new Zend_Db_Expr("CONCAT(room_type_desc, '-', room_characteristics_desc)")
))
->join(array('cr' => 'contracts_rooms'),
'ca.contract_rooms_id = cr.id',
array())
->join(array('rt' => 'room_types'),
'cr.room_id = rt.id',
array('room_type_desc'))
->join(array('rc' => 'room_characteristics'),
'cr.char_id = rc.id',
array('room_characteristics_desc'))
->where('contract_id = ?', $contractId);
var_dump($this->getDbTable()->fetchAll($query));die;
我越来越:
Select查询语句不能与其他表”
错误来参加由Zend/Db/Table/Select::assemble()
在这里,你有一些内部装配():
// Check each column to ensure it only references the primary table
if ($column) {
if (!isset($from[$table]) || $from[$table]['tableName'] != $primary) {
var_dump($from[$table]['tableName'], $primary);die;
require_once 'Zend/Db/Table/Select/Exception.php';
throw new Zend_Db_Table_Select_Exception('Select query cannot join with another table');
}
}
个
的var_dump()
打印:
串(10) “room_types” 字符串(19) “contracts_allotment”
任何想法?
