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
