SQL code:
-- 给个例子给你，自己看着办吧：

-----------------------------------------------------------------------------
create or replace package pkg_emp_info
as
type myrctype is ref cursor;
procedure emp_info_proc(v_empno in number default 0,v_ename in VARCHAR2, v_deptno number default 0,p_rc out myrctype);
end pkg_emp_info;

create or replace package body pkg_emp_info
as
procedure emp_info_proc(v_empno in number default 0,v_ename in VARCHAR2, v_deptno number default 0,p_rc out myrctype)
is
sqlstr VARCHAR2(2000);
begin

sqlstr :=
'SELECT * from emp e where 1=1';

if v_empno<>0 then
sqlstr := sqlstr||' and e.empno='||v_empno;

sqlstr := sqlstr||' and e.ename like ''%||v_ename||%''';
