错误还蛮多哦，其实LZ自己根据报错信息都可以调出来呢
SQL code
CREATE TABLE test(id number, value varchar2(200));

create or replace package a_package_name
as  
  PROCEDURE get_procedure_name
  (
  v_arg1 number,
  v_arg2 VARCHAR2/*(200)*/,
  refCur_return out SYS_REFCURSOR ,
  v_total_Count out varchar2
  );
END;
/
create or replace package body a_package_name
as  
procedure get_procedure_name
(
  v_arg1 number,
  v_arg2 varchar2,
  refCur_return out SYS_REFCURSOR,
  v_total_Count out varchar2
)
is
numArg1 number := '';
strArg2 varchar2(200) := '';
strSql varchar2(200) := '';
strQuery varchar2(200) := '';
strCondition varchar2(200) := ' where 1=1 ';

Begin
  if v_arg1 is not null and length(v_arg1)>0 then   
  numArg1 := v_arg1;
  strCondition := ' '|| strCondition ||' and id = '|| numArg1 ||' ';
  end if;
  if v_arg2 is n
