missing expression in oracle dynamic sql -

am trying print hierarchy information through store procedure. when execute simple statement able retrieve records. when running in loop using cursor, throwing missing expression.

declare  --var1 varchar2(200):='''810011148'''; resutl1 varchar2(2000); v__rowid_party_child_fk  varchar2(2000); v__rowid_party_parent_fk   varchar2(2000); v_connectby_iscycle  number; stm1 varchar2(2000); var1 varchar2(200) ;    cursor c1 select distinct s_rowid_party_child_fk  var1 c_rel_party_xref  rownum <10;   begin  c2 in c1  loop    stm1 :=  'select * (   select level, s_rowid_party_child_fk , s_rowid_party_parent_fk  ,connect_by_iscycle iscycle   c_rel_party_xref   start  s_rowid_party_child_fk ='|| var1||'    connect nocycle  prior   s_rowid_party_parent_fk=s_rowid_party_child_fk )a  a.iscycle=1';   -- execute immediate stm1 ;  execute immediate stm1 resutl1, v__rowid_party_child_fk,v__rowid_party_parent_fk , v_connectby_iscycle ; dbms_output.put_line(resutl1 || ','|| v__rowid_party_child_fk || ','|| v__rowid_party_parent_fk || ','||  v_connectby_iscycle); end loop; end; 

thanks

should be:

cursor c1 select distinct s_rowid_party_child_fk c_rel_party_xref  rownum <10; 

and

begin   c2 in c1   loop     select *        resutl1, v__rowid_party_child_fk,v__rowid_party_parent_fk , v_connectby_iscycle       (           select level, s_rowid_party_child_fk , s_rowid_party_parent_fk  ,connect_by_iscycle iscycle             c_rel_party_xref            start  s_rowid_party_child_fk = c2.s_rowid_party_child_fk           connect nocycle  prior   s_rowid_party_parent_fk=s_rowid_party_child_fk             )        a.iscycle=1     ;     dbms_output.put_line(resutl1 || ','|| v__rowid_party_child_fk || ','|| v__rowid_party_parent_fk || ','||  v_connectby_iscycle)   end loop; end;
