第一次用临时表的感受：

WITH 
WOTotal AS
(
 SELECT sysuser.REALNAME,count(1) AS TotalCount FROM WO_OperaionWorkOrderBills owobill WITH(nolock)
 LEFT JOIN SYS_USER sysuser WITH(NOLOCK) ON sysuser.USERID=owobill.OWOReceiver 
 WHERE sysuser.REALNAME IS NOT NULL  and OWOState!='OWO_Completed'
 GROUP BY sysuser.REALNAME
),
WOAdd AS
(
SELECT sysuser.REALNAME,count(1) AS AddCount  FROM WO_OperaionWorkOrderBills owobill WITH(nolock)
 LEFT JOIN SYS_USER sysuser WITH(NOLOCK) ON sysuser.USERID=owobill.OWOReceiver 
 WHERE sysuser.REALNAME IS NOT NULL and OWOState='OWO_Add'
 GROUP BY sysuser.REALNAME
),
WODispatched AS
(
SELECT sysuser.REALNAME,count(1) AS DispatchedCount  FROM WO_OperaionWorkOrderBills owobill WITH(nolock)
 LEFT JOIN SYS_USER sysuser WITH(NOLOCK) ON sysuser.USERID=owobill.OWOReceiver 
 WHERE sysuser.REALNAME IS NOT NULL and OWOState='OWO_Dispatched'
 GROUP BY sysuser.REALNAME
)
SELECT TOP 10 '1' as time_sec, WOTotal.RealName as metric ,TotalCount as value,isnull(AddCount,0) AS 新建,isnull(DispatchedCount,0) 派单
 FROM WOTotal 
 LEFT JOIN WOAdd ON WOTotal.RealName=WOAdd.RealName
 LEFT JOIN WODispatched ON WOTotal.RealName=WODispatched.RealName 

ORDER BY TotalCount desc
