PL/SQL:错误“PLS-00306:调用中的参数数量或类型错误"为数字表触发

问题描述

我正在尝试使用确切的过程签名调用 API，但不知何故，我认为数字表无法正确识别.

I'm trying to call an API using the exact procedure signature, but somehow the table of numbers I don't think is recognize correctly.

API 定义:

TYPE NUMLIST IS TABLE OF NUMBER INDEX BY VARCHAR2(50);

PROCEDURE GETSERVICES_API
(
   I_DIMOBJID IN NUMBER, I_OBJECTID IN NUMBER, I_FILTER IN NUMBER, 
   O_ERRORCODE OUT NUMBER, O_ERRORTEXT OUT VARCHAR2, O_SERVICELIST OUT NUMLIST
);

我对 API 的调用:

My call of API:

DECLARE

   TYPE NUMLIST IS TABLE OF NUMBER INDEX BY VARCHAR2(50);
   lt_SERVICELIST              NUMLIST;

   ls_errortext             varchar2(100);
   ln_errorcode             number;

BEGIN


    PKGCOMSUPPORT_SERVICE.GETSERVICES_API(I_DIMOBJID => 6,
                                          I_OBJECTID => 5263,
                                          I_FILTER => 3,
                                          O_ERRORCODE => ln_errorcode,
                                          O_ERRORTEXT => ls_errortext,
                                          O_SERVICELIST => lt_SERVICELIST);

END;

当我运行 API 调用时，我得到:PLS-00306:调用GETSERVICE_API"时参数类型的数量错误

When I run my call of API I got: PLS-00306: wrong number of types of arguments in call to 'GETSERVICE_API

知道为什么吗?谢谢

推荐答案

您面临 PLS-00306 错误的原因是 NUMLIST 集合类型不兼容，已定义在匿名 PL/SQL 块中定义的包规范和 NUMLIST 集合类型中.尽管这两种集合类型的定义相同，但它们并不兼容.在您的匿名 PL/SQL 块中，您必须声明一个 PKGCOMSUPPORT_SERVICE.NUMLIST 数据类型的变量，然后将其传递给 GETSERVICES_API 过程.

The reason why you are facing the PLS-00306 error is incompatibility of NUMLIST collection type, defined in the package specification and NUMLIST collection type defined in the anonymous PL/SQL block. Even though definitions of those two collection types are the same, they are not compatible. In your anonymous PL/SQL block you have to declare and then pass into the GETSERVICES_API procedure a variable of PKGCOMSUPPORT_SERVICE.NUMLIST data type.

create or replace package PKG as
  type t_numlist is table of number index by varchar2(50);
  procedure SomeProc(p_var in pkg.t_numlist);
end;
/

create or replace package body PKG as
  procedure someproc(p_var in pkg.t_numlist) is
  begin
    null;
  end;
end;
/

declare
  type t_numlist is table of number index by varchar2(50);
  l_var t_numlist;
begin
  pkg.someproc(l_var);
end;

ORA-06550: line 5, column 3:
PLS-00306: wrong number or types of arguments in call to 'SOMEPROC'

declare
  --type t_numlist is table of number index by varchar2(50);
  l_var pkg.t_numlist;
begin
  pkg.someproc(l_var);
end;

anonymous block completed
