mysql_db_sql_Sum集合中两个表不能内连接，提高查询效率

需要根据时间进行查询这段时间洗了多少次车
SELECT wx.UserName AS ‘用户名称‘,
 wx.Telephone AS ‘手机号‘, 
IFNULL(TotalCarCount,0) AS ‘共洗车次数‘,
IFNULL(BigCarCount,0) AS ‘大车洗车次数‘,
IFNULL(SmallCarCount,0) AS ‘小车洗车次数‘,
IFNULL(count(WashOrderID),0) AS ‘充值总次数‘,
IFNULL(SUM(case cd.CardType when 13 then 1 else 0 end),0) AS ‘充值次数‘,
IFNULL(SUM(case cd.CardType when 12 then 1 else 0 end),0) AS ‘购卡次数‘,
IFNULL(FORMAT(SUM(cd.WashOrderActualMoney),2),0) AS ‘实际消费金额‘,
IFNULL(SUM(WashOrderIntegral*sc.ConfigValue),0) AS ‘积分使用量‘,
IFNULL(FORMAT(SUM(cd.WashOrderDeductible),2),0) AS ‘优惠券使用金额‘
FROM t_wxuserinfos AS wx 
LEFT JOIN (SELECT * FROM t_cardrechargedetails WHERE WashOrderSign = ‘e252a4a9-536a-4eb3-ae40-a7b9df95176b‘) cd ON wx.UserID=cd.UserID 
LEFT JOIN t_carwashinformation ci ON wx.UserID=ci.UserID 
LEFT JOIN (SELECT ConfigValue FROM t_sysconfig WHERE ConfigName=‘integralMoneyRatio‘) AS sc ON 1=1  
LEFT JOIN (SELECT UserID,COUNT(oc.OrderID) AS TotalCarCount,SUM(case oc.CarTypeID when 1 then 1 else 0 end) AS BigCarCount,
SUM(case oc.CarTypeID when 2 then 1 else 0 end) AS SmallCarCount FROM t_orderconsumption AS oc  GROUP BY UserID) AS b
ON wx.UserID = b.UserID 
GROUP BY wx.UserID

加粗为关键的
SELECT cd.WashOrderTime FROM t_cardrechargedetails cd
