SQL & PL/SQL

Dear everybody

I'm new to oracle. I'm using Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 in window vista.

recently, i try to run this code :

select u.name, o.obj#, o.name,
decode(o.type#, 2, 'TABLE', 4, 'VIEW')
from sys.user$ u, sys.obj$ o
where o.owner# = u.user#
and o.linkname is null
and o.type# in (2, 4)
and (o.owner# = uid
or
obj# in (select obj#
from sys.objauth$
where grantee# in (select kzsrorol from x$kzsro)
or grantee#=uid
)
);

and encounter error :


Error starting at line 1 in command:
select u.name, o.obj#, o.name,
decode(o.type#, 2, 'TABLE', 4, 'VIEW')
from sys.user$ u, sys.obj$ o
where o.owner# = u.user#
and o.linkname is null
and o.type# in (2, 4)
and (o.owner# = uid
or
obj# in (select obj#
from sys.objauth$
where grantee# in (select kzsrorol from x$kzsro)
or grantee#=uid
)
)
