 select pui.UserName '@USERNAME',  --必须把节点的属性放在第一位
     pui.UserID 'USERID',
     pui.UserName 'EMAIL',
     pui.RoleDes 'ROLE/@ROLEDES',
     pui.RoleID 'ROLE/ROLEID',
     pui.RoleName 'ROLE/ROLENAME',
     pui.OperationType 'ROLE/OPERATION'
     from dbo.vwPortalUserIncrement pui where pui.UserID in
  (select distinct top (@pageSize) pu.UserID from dbo.tblAccountsPortalUserIncrements pu
   where pu.Status = '00' or pu.Status = '03'
   order by pu.UserID asc
  )
  FOR XML PATH('USER'),ROOT('USERROLES');
