Pl /sql过程不允许传递表名/视图名作为参数

Question

我有一个小的pl/sql过程，我试图在12c中运行，代码如下:

create or replace procedure p_ins_tbl(tbl_name in varchar2) as
begin 
execute immediate 'insert into ' ||tbl_name|| 'values(121,''asdfasdf'',6)' ;
end p_ins_tbl;

编译成功，

，当我试图执行:exec p_ins_tbl(countries);

我得到的错误是:

Error starting at line 6 in command:
exec p_ins_tbl(countries)
Error report:
ORA-06550: line 1, column 17:
PLS-00357: Table,View Or Sequence reference 'COUNTRIES' not allowed in this context
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
06550. 00000 -  "line %s, column %s:n%s"
*Cause:    Usually a PL/SQL compilation error.
*Action:

为什么我得到这个?如果有什么问题，请纠正我，谢谢。
