Barbara's questions

我需要创建一个 varray，它的大小必须是过程的参数，例如

create or replace procedure x (cant number)
as
type arreglo is varray(cant) of number;
elarreglo arreglo :=arreglo();
begin
        elarreglo(1):=(9);
        ....
        ....
end;

我尝试这样做，但它显示此错误：

LINE/COL ERROR
-------- -----------------------------------------------------------------
3/24     PLS-00103: Encountered the symbol "CANT" when expecting one of
         the following:
         <a number>
         The symbol "<a number> was inserted before "CANT" to continue.

我做错了什么？可以做我正在尝试的事情吗？
