我刚刚遇到了 DBMS_PARALLEL_EXECUTE 的一些奇怪行为(至少对我来说)。查看我的预设(以 SYS 身份执行):
-- Preset
drop user usr1 cascade;
create user usr1 identified by usr1;
create or replace procedure usr1.do_stuff(p1 in number, p2 in number)
is
begin
dbms_output.put_line('I did stuff!');
end;
/
drop user usr2 cascade;
create user usr2 identified by usr2;
grant connect to usr2;
grant create job to usr2;
drop role stuff_doer cascade;
create role stuff_doer;
grant execute on usr1.do_stuff to stuff_doer;
grant stuff_doer to usr2;
所以我创建了 2 个用户,第一个用户有一个程序stuff_doer
角色。后来这个角色被交给了usr2
.
然后我检查它为usr2

请参阅:当我执行时do_stuff
直接执行程序 - 它按预期完成。但是当我使用DBMS_PARALLEL_EXECUTE
I get identifier must be declared
错误。我在授予特权时遗漏了什么吗?
I found here https://docs.oracle.com/database/121/ARPLS/d_parallel_ex.htm#ARPLS67333这句话:The CHUNK_BY_SQL, RUN_TASK, and RESUME_TASK subprograms require a query, and are executed using DBMS_SQL.
我试图明确地dbms_sql.parse
我的陈述但也完成了。
任何帮助将不胜感激,因为我没有得到当前的情况。是的,我可以直接授予权限,但这对我来说仍然很棘手。
