sql query在一個查詢中計算多個定義的列數

Question

我一直在尋找這個網站來嘗試和a）更好地理解我的問題和b）找到一些解決方案的幫助，但似乎我看到的一切都是輕微的我的問題，所以我在這裏要問的一些意見不同，請:)

我有以下查詢

SELECT *, 
(date_end < 1392569012) AS expired, 
(date_start > 1392569012) AS pending, 
(date_end > 1392569012 && date_start <= 1392569012) AS active 
FROM tbl_events AS event 
LEFT JOIN tbl_event_events AS ee ON event.event_id = ee.event_id 
WHERE event.event_type = 5 && event.user_id = '".$user->getUserID()."' 
ORDER BY expired,pending,active 

這determins的列表的狀態。

現在我想做的是統計的活躍人數，待和過期上市

這是我更新的查詢，但它只返回1行，但正確的和值？

SELECT *, 
SUM(date_end < 1392569012) AS expiredCount, 
SUM(date_start > 1392569012) AS pendingCount, 
SUM(date_end > 1392569012 && date_start <= 1392569012) AS activeCount,    
(date_end < 1392569012) AS expired, 
(date_start > 1392569012) AS pending, 
(date_end > 1392569012 && date_start <= 1392569012) AS active 
FROM tbl_events AS event 
LEFT JOIN tbl_job_events AS jobvent ON event.event_id = jobvent.event_id 
LEFT JOIN tbl_job_department AS jdept ON event.event_id = jdept.event_id 
LEFT JOIN tbl_departments as dept ON jdept.department_id = dept.department_id 
WHERE event.event_type = 2 && event.user_id = '".$user->getUserID()."' 
ORDER BY expired,pending,active 

有人可以幫助我得到這個工作，請！

感謝您的幫助

因爲主動將1該過濾器和0他人，加總和有源濾波器獲得的行數滿足該過濾器。

SELECT *, (SELECT SUM(date_end > 1392569012 && date_start <= 1392569012) 
FROM tbl_events AS event 
LEFT JOIN tbl_event_events AS ee ON event.event_id = ee.event_id 
WHERE event.event_type = 5 && event.user_id = '".$user->getUserID()."' 
ORDER BY expired,pending,active), 
(date_end < 1392569012) AS expired, 
(date_start > 1392569012) AS pending, 
(date_end > 1392569012 && date_start <= 1392569012) AS active 
FROM tbl_events AS event 
LEFT JOIN tbl_event_events AS ee ON event.event_id = ee.event_id 
WHERE event.event_type = 5 && event.user_id = '".$user->getUserID()."' 
ORDER BY expired,pending,active
