MySQL存儲過程的查詢

我有一個返回最近或最後插入廣告MySQL存儲過程的查詢

的發送的電子郵件以下存儲過程：「現在我的目的，只顯示其已在活動」派：計數大於‘0’如何更大可我更改以下SP做到這一點，因爲現在是返回所有的活動，包括「0」和大於「0」」 ..

代碼是...

DELIMITER $$ 

DROP PROCEDURE IF EXISTS `couponcrusaderdev`.`sp_tblemailcampaignLoadTop4`$$ 

CREATE DEFINER=`anyone`@`000.000.00.00` PROCEDURE `sp_tblemailcampaignLoadTop4`(p_UserID Int(11)) 
    SQL SECURITY INVOKER 
BEGIN 
SELECT EC.*,(Select MailChimpCampaignID from tblcampaignschedule where EC.CampaignID=tblcampaignschedule.CampaignID) as MailChimpCampaignID,(Select count(MailChimpCampaignID) from tblcampaignschedule) as msent,CT.CampaignType, (Select tblcampaignschedule.ScheduleDateTime from tblcampaignschedule 
where EC.CampaignID=tblcampaignschedule.CampaignID order By ScheduleDateTime desc limit 1) as CampaignDateTime,
