如何在oracle sql开发人员中运行存储过程？

我试图运行这个存储过程

DECLARE
  P_TICKER_SERIAL VARCHAR2(200);
  P_SECTOR_CODE   VARCHAR2(200);
  P_SOURCE_ID     VARCHAR2(200);
  P_COUNTRY_CODE  VARCHAR2(200);
  P_FILTER_TYPE   NUMBER;
  CUR_OUT         SYS_REFCURSOR;
  dbUserTable     DBUSER%rOWTYPE;
BEGIN
  P_TICKER_SERIAL :='14232';
  P_SECTOR_CODE   := '15';
  P_SOURCE_ID     := 'TDWL';
  P_COUNTRY_CODE  := 'SA';
  P_FILTER_TYPE   := 1;

  PKG_name.GET_user(
    P_TICKER_SERIAL => P_TICKER_SERIAL,P_SECTOR_CODE   => P_SECTOR_CODE,P_SOURCE_ID     => P_SOURCE_ID,P_COUNTRY_CODE  => P_COUNTRY_CODE,P_FILTER_TYPE   => P_FILTER_TYPE,CUR_OUT         => CUR_OUT
  );
  open CUR_OUT;
  LOOP
    FETCH CUR_OUT INTO dbUserTable;
    dbms_output.put_line(dbUserTable.email);
  END LOOP;
  CLOSE CUR_OUT;
END;
 /

但它给我这个错误

有谁知道有什么问题？
谢谢。

尝试执行这样的过程，

var c refcursor;
execute pkg_name.get_user('14232','15','TDWL','SA',1,:c);
print c;
