存储过程 create or replace package pkg_test as type t_cursor is ref cursor; procedure sp_get_catalogs(p_userid in number, cur_catalogs out t_cursor); end; create or replace package body pkg_test as procedure sp_get_catalogs(p_userid in number, cur_catalogs out t_cursor) is v_sql varchar2(500); begin if p_userid = 0 then open cur_catalogs for select userid, loginid, name from tuser; else v_sql := 'select userid,loginid,name from tuser where userid=:w_userid'; open cur_catalogs for v_sql using p_userid; end if; exception when others then dbms_output.put_line('other exception'); end sp_get_catalogs; end pkg_test;sqlplus调试代码 variable v_cur refcursor; variable v_userid number; set autoprint off; begin :v_userid := -9222229; end; / execute pkg_test.sp_get_catalogs(:v_userid, :v_cur); print v_cur;总结 pl/sql developer 里的command window里面输入(sqlplus调试代码)调试存储过程会出现“refcursor don't supported!“的错误，换到sqlplus里面调试一切正常。参考文档 sql*plus user's guide and reference release 9.2
