--创建过程,参数为sys_refcursor,为out型
create or replace procedure aabbsys_refcursor(o out sys_refcursor) is
begin
open o for select * from basplumain;
end;
---
--测试过程,使用aabbsys_refcursor传出的值
create or replace procedure aabb_test_sys_refcursor(return out int)is
type t_basplumain is table of basplumain%rowtype;
t_plu t_basplumain;
v sys_refcursor;
begin
aabbsys_refcursor(v);
fetch v bulk collect into t_plu;
for i in 1..t_plu.count loop
dbms_output.put_line(t_plu(i).pluname);
end loop;
end;

--sqlplus测试脚本
--set serveroutput on
declare
v_return int default 0;

type type_refcur is ref cursor;
cur_refcur type_refcur; ---自定义的ref cursor
cur_sysref sys_refcursor; --- 使用系统预定义的sys_refcursor v_sql varchar(4000) :动态拼接一个查询sql: ;
开启游标: open cur_xxx for v_sql 时, cur_sysref 即 sys_refcursor可以, 而cur_refcur 即 ref cursor 不可以;
