如何使用此查询

来区分Page_Name

   Select A.UserId,Page_Name,Region_Name, Content_Name,Chart_Src
   from  DWH_DBPages A 
   LEFT OUTER JOIN DWH_DashBoardA B ON A.sysRegionSno=B.sysRegionSno 
   LEFT OUTER JOIN DWH_DashBoardB C ON B.sysContentSno=C.sysContentSno 
   LEFT OUTER JOIN DWH_DashboardC D ON C.sysTypeSno=D.sysTypeSno
   LEFT OUTER JOIN DWH_DashboardD E ON D.sysChartSno=E.sysChartSno
   WHERE A.UserId = 'xxxxxxxxx' AND A.sysMenuSno = 'xxxx'

select distinct( Page_Name) 
from (Select A.UserId,Page_Name,Region_Name, Content_Name,Chart_Src 
     from DWH_DBPages A 
     LEFT OUTER JOIN DWH_DashBoardA B ON A.sysRegionSno=B.sysRegionSno 
     LEFT OUTER JOIN DWH_DashBoardB C ON B.sysContentSno=C.sysContentSno 
     LEFT OUTER JOIN DWH_DashboardC D ON C.sysTypeSno=D.sysTypeSno 
     LEFT OUTER JOIN DWH_DashboardD E ON D.sysChartSno=E.sysChartSno 
     WHERE A.UserId = 'xxxxxxxxx' 
     AND A.sysMenuSno = 'xxxx')aa
