Zend Framework 2 can't get fields from joined tables - mysql

Question

I can't get fields from the joined table. Here is my situation, I have two tables called "query" and "region" handeled by two controllers QueryCOntroller and RegionController. From the QueryController I tried to join the "query" to "region". to get the name of "query"'s "region"'s name in a view file but I can't get the desired field
public function fetchMine($myid)
{
$sql = new Sql( $this->tableGateway->adapter ) ;
$where = new Where() ;
$where->equalTo('agent_id', $myid) ;
$select = $sql->select() ;
$select -> from ( $this->tableGateway->getTable() )
-> join ( 'region' , 'query.agent_id = region.id')
->columns(array('*'))
-> where( $where ) ;
$resultSet = $this->tableGateway->selectWith($select);
return $resultSet;
}
in my Module.php, getServiceConfig()
'Management\Model\QueryTable' => function($sm) {
$tableGateway = $sm->get('QueryTableGateway');
$table = new QueryTable($tableGateway);
return $table;
},
'QueryTableGateway' => function ($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new Query());
return new TableGateway('query', $dbAdapter, null, $resultSetPrototype);
},

Answer 1

try:
public function fetchMine($myid)
{
$select = new Select ();
$select->from ( $this->tableGateway->getTable() );
$select->join ( 'region' , 'query.agent_id = region.id' , Select::SQL_STAR , Select::JOIN_LEFT )
$select->where( array( 'agent_id'=>$myid ) );
$resultSet = $this->tableGateway->selectWith($select);
return $resultSet;
}
then you must extends Query from Region for getting all attributes of query and region,
Query.php:
use Management\Model\Region;
class Query extends Region
{
//...
}

Answer 2

The Query class must have attribute has the same name of region name in region table
if you want to use another name just use sql alias
if you want to add more attributes from region table you must add them all in Query class
