I know it is possible to perform followings with ZF 2
$select->join(//$select is zend db sql select
                            array(
                                'cs' => 'table1'), 
                                'ts.id=cs.cs_id', 
                                array(),$select::JOIN_TYPE);
according to the manual (http://framework.zend.com/manual/2.2/en/modules/zend.db.sql.html)JOIN_TYPE can be any of follows, and they are producing what they mean
JOIN_INNER 
JOIN_OUTER 
JOIN_LEFT   
JOIN_RIGHT 
but I simply want to add normal join $select->join produce an Inner join. Dose any one know any way
