MySQL的计数ID基于不同的列值

嘿，我想要计算所有的ids（这是别名ACTUAL_ENTRIES），这些与连接表中的列rt.x_type无关。我使用zend框架。这是我的整个ORM查询。MySQL的计数ID基于不同的列值

$columns = array(
    'EV.id as EVENT_ID', 
    'EV.name as EVENT_NAME', 
    'DATE_FORMAT(CONVERT_TZ(FROM_UNIXTIME(EV.start_time), "UTC", LO.time_zone), "%m/%e/%Y %a %r") as EVENT_START_DATE', 
    'LO.time_zone as TIME_ZONE', 
    'coalesce(EV.expected_entry, "") as EXPECTED_ENTRIES', 
    $db->quoteInto('count(if(RT.x_type NOT IN ("CREDIT","EXTERNAL"),EN.id,0)) AS ACTUAL_ENTRIES'), 
    $db->quoteInto('sum(IF(EN.type != ?, 1, 0)) AS ACTUAL_ATHLETES', Entry::ENTRY_TYPE_TEAM), 
    $db->quoteInto('sum(IF(EN.type = ?, 1, 0)) AS ACTUAL_TEAMS', Entry::ENTRY_TYPE_TEAM), 
    'coalesce(T.name,"") as TIMER_NAME', 
    'coalesce(T.phone, "") as TIMER_PHONE', 
    'coalesce(T.sales_region, "") as SALES_REGION' 
); 

$rows = $this->_readonlydb->select() 
    ->from(array('EV' => 'event'),'') 
    ->join(array('LO' => 'location'),'EV.location_id = LO.id','') 
    ->joinLeft(array('RT' => 'reg_transaction'), 
        "RT.event_id = EV.id AND 
        (RT.is_test = 0 OR RT.is_test IS NULL) AND 
        RT.x_response_code = " . RegTransaction::RESPONSE_CODE_SUCCESS . "", '') 
    ->joinLeft(array('EN' => 'entry'), 'EN.trans_id = RT.id', '') 
    ->joinLeft(array('T' => 'organization'), 'T.id = EV.timer_id', '') 
    ->where('EV.is_test_event = ?', 0) 
    ->where("EN.status NOT IN (?)", array(Entry::ENTRY_STATUS_WITHDRAWN, Entry::ENTRY_STATUS_NEW)) 
    ->where('YEARWEEK(FROM_UNIXTIME(EV.start_time), 3) = ?', date("YW")) 
    ->group('EV.id') 
    ->columns($columns) 
    ->query() 
    ->fetchAll() 
;

重要组成部分，是

$db->quoteInto('count(if(RT.x_type NOT IN ("CREDIT","EXTERNAL"),EN.id,0)) AS ACTUAL_ENTRIES'),

这不工作。可以有人建议我的东西

你开发了一个SQL查询吗？如果是这样，请给它。 –

You can use zf2 expression. 
    new \Zend\Db\Sql\Expression('count(if(RT.x_type NOT IN ("CREDIT","EXTERNAL"),EN.id,0)) AS ACTUAL_ENTRIES') 
It works for me in zf2
