帮忙 PROCEDURE 的应用问题

solaris_yschang

有两个表 sys_navigation 和 sys_power
在这两表上我建立了这样一个存储过程

( userid in number,
  ugtype in number,
  tmove out   sys_navigation.tmove%TYPE,
  xh       out   sys_navigation.xh%TYPE,
  windowname out sys_navigation.windowname%TYPE,
  tname            out  sys_navigation.tname%TYPE,
  bmpname       out sys_navigation.bmpname%TYPE,
  selectedbmpname  out  sys_navigation.selectedbmpname%TYPE,
  selected                 out   sys_navigation.selected%TYPE,
  mopen         out  sys_navigation.mopen%TYPE,
  opened       out sys_navigation.opened%TYPE,
  children       out  sys_navigation.children%TYPE,
  siblings        out  sys_navigation.siblings%TYPE,
  tlevel           out  sys_navigation.tlevel%TYPE,
  powertype  out   sys_power.powertype%TYPE
  )
as
begin
   select sys_navigation.tmove,
    sys_navigation.xh,
    sys_navigation.windowname,
    sys_navigation.tname,
    sys_navigation.bmpname,
    sys_navigation.selectedbmpname,
    sys_navigation.selected,
    sys_navigation.mopen,
    sys_navigation.opened,
    sys_navigation.children,
    sys_navigation.siblings,
    sys_navigation.tlevel,
    sys_power.powertype
into
tmove,
xh,
windowname,
tname,
bmpname,
selectedbmpname,
selected,
mopen,
opened,
children,
siblings,
tlevel,
powertype
from sys_navigation,sys_power
where ( sys_power.navigationxh = sys_navigation.xh)  and ((sys_power.userorgroupid = userid) and (sys_power.ugtype = ugtype))
    and ( sys_power.powertype <> 0) and (sys_navigation.syscode in (select sys_runconfig.currentsyscode from sys_runconfig));
end;

在PB中建立以该存储过程为数据源的数据窗口，按理论来说该数据窗口应该只要提供 2 个 in 参数就可以了，但在建数据窗口时候必须把所有参数（包括ｏｕｔ)，请教高手，如何只要提供这两个 in 参数就可以？
