oracle的預存程序裡怎樣調用動態變數

create or replace procedure SYSRINGALL_TEST is
all_tmp_name char(30);
all_name char(30);
begin
if all_tmp_name is null then
select 'ring_all_old_'||to_char(sysdate,'yyyymm')||'_tmp' into all_tmp_name from dual;
end if;
if all_name is null then
select 'ring_all_old_'||to_char(sysdate,'yyyymm') into all_name from dual;
end if;
------由ALL進TMP---------
insert into all_tmp_name
select * from all_name;
commit;
end SYSRINGALL_TEST;

==========================

其實就是想動態產生ring_all_old_200606和ring_all_old_200606_tmp

這兩個表名讓下面使用

但老是編譯出錯,如果把下面改成

insert into ring_all_old_200606_tmp

select * from ring_all_old_200606;

就能編譯通過.

請問該怎樣改啊?

create or replace procedure SYSRINGALL_TEST is
all_tmp_name char(30);
all_name char(30);
tmp_str varchar(2000);
begin
if all_tmp_name is null then
select 'ring_inkfish_'||to_char(sysdate,'yyyymm')||'_tmp' into all_tmp_name from dual;
end if;
if all_name is null then
select 'ring_inkfish_'||to_char(sysdate,'yyyymm') into all_name from dual;
end if;
tmp_str :='insert into '||all_tmp_name||' select * from '||all_name;
execute immediate tmp_str;
commit;
end SYSRINGALL_TEST;

嘿嘿，不容易啊！！自己搞定啦！希望能對大家有協助！
