Question

我想将表类型作为参数传递给过程。

create or replace package FOO is
    type FOOTYPE is record (
        FOOTYPE_A varchar2(5) null,
        FOOTYPE_B varchar2(5) null,
        FOOTYPE_C varchar2(5) null
    ); 

    type FOOTYPETABLE is table of FOOTYPE;
...
    procedure sendNew (
        table_a in FOOTYPETABLE
    ) is
        a number;
    begin
       ...
    end sendNew;
...
end FOO;

declare
    type bartabletype is table of FOO.FOOTYPE index by binary_integer;
    bartable bartabletype;
    begin
        bartable(0).FOOTYPE_A := '';
        bartable(0).FOOTYPE_B := '';
        bartable(0).FOOTYPE_C := '';
        bartable(1).FOOTYPE_A := '';
        bartable(1).FOOTYPE_B := '';
        bartable(1).FOOTYPE_C := '';
    FOO.sendNew(bartable);
end;

但甲骨文说：

＆＃34; ora-00306错误的数字或类型的参数＆＃34;。

为什么？

Answer 1

当你期望pl / sql表（嵌套表）时，你试图传入一个关联数组（索引）。例如，执行以下操作：

create or replace package tpkg as
  type t_myrec is record (
      val1 varchar2(1000),
      val2 varchar2(1000)
  );
  type t_myrec_tab is table of t_myrec;

  procedure recv_ary(i_ary in t_myrec_tab);
end;

create or replace package body tpkg as
    procedure recv_ary(i_ary in t_myrec_tab) is
    begin
      -- do something here
      dbms_output.put_line('Array has ' || i_ary.count || ' elements');
    end;
end;

并使用它：

declare
  some_ary tpkg.t_myrec_tab;
begin
  select object_name, object_type
  bulk collect into some_ary
  from user_objects
  where rownum <= 100;

  tpkg.recv_ary(some_ary);
end;

注意我将“some_ary”声明为“tpkg.t_myrec_tab”类型。换句话说，我特意引用了包类型，所以我知道它正确的集合类型。

Answer 2

这可能是因为FOOTYPETABLE被声明为过程sendNew（）参数类型，它与您尝试传递给它的table of FOO.FOOTYPETABLE不同。

Answer 3

bartable变量必须是FOO.FOOTYPETABLE类型，而不是bartabletype

PL SQL表参数
