Question

I am trying to replicate this query using zend framework:

SELECT 
    activitytype.description, 
    activity.datecompleted

FROM
    clientactivity
INNER JOIN activity
    ON activity.activityID = clientactivity.activityid
INNER JOIN activitytype
    ON activitytype.activitytypeid = activity.activitytypeid

WHERE
    clientactivity.clientid = 100

This is what I have so far:

$select = $dbTable->select(Zend_Db_Table::SELECT_WITH_FROM_PART);

$select->setIntegrityCheck(false);
$select->where('clientactivity.clientid = ?', $clientID);

$select->join('activity', 'activity.activityid = clientactivity.activityid');
$select->join('activitytype', 'activitytype.activitytypeid = activity.activitytypeid');

$select->columns(array('activitytype.description', 'activity.datecompleted'));

I seem to be having problems with the columns option, it doens’t seem to be limiting the columns and I am ending up with
clientactivity.* etc in the column list in the query.

What am I doing wrong?

Thanks,
Martin

Answer 1

Try instead of the $select->columns();

$select->from('activitytype.description', 'activity.datecompleted');

UPDATE:

This example makes us of a generic database handler:

$db = Zend_Db::factory('Pdo_Mysql', array(
            'host'     => '127.0.0.1',
            'username' => 'yourusername',
            'password' => 'somepassword',
            'dbname'   => 'yourdbname'
        ));

 $select = $db->select(Zend_Db_Table::SELECT_WITH_FROM_PART);
 $select->from('tableName','fieldName')
         ->join('joinTable', 'joinTable.keyId = tableName.keyId',array())
         ->where('tableName.userId = ?', $userId);

 $resultSet = $db->fetchAll($select);

The key piece is the blank array at the end of the join statements that specifies no records to be returned from the joined table.
