Question

我正在处理一个重载包，并想知道两件事。

1）有没有办法获得更多关于发生了什么错误的信息，例如它发生的行号，因为Failed to resolve object details接缝有点模糊。

2）这句话似乎有什么问题？

   CREATE OR REPLACE PACKAGE shop_query_pkg IS
     procedure shop_info 
      (p_id IN bb_shopper.idshopper%TYPE,
       p_firstname out bb_shopper.firstname%TYPE);
      procedure shop_info 
      (p_id IN bb_shopper.lastname%TYPE,
       p_firstname out bb_shopper.firstname%TYPE);
    END;
    /
    CREATE OR REPLACE PACKAGE BODY show_query_pkg IS
     procedure shop_info 
      (p_id IN bb_shopper.idshopper%TYPE,
       p_firstname out bb_shopper.firstname%TYPE);
      IS
     BEGIN
       SELECT firstname
        into p_firstname
        FROM bb_shopper
        WHERE idshopper = p_id;
     EXCEPTION
      WHEN NO_DATA_FOUND THEN
       DBMS_OUTPUT.PUT_LINE('ID does not exist');
     END;
     -- second procedure
     procedure shop_info 
      (p_id IN bb_shopper.lastname%TYPE,
       p_firstname out bb_shopper.firstname%TYPE);
      IS
     BEGIN
       SELECT firstname
        into p_firstname
        FROM bb_shopper
        WHERE lastname = p_id;
     EXCEPTION
      WHEN NO_DATA_FOUND THEN
       DBMS_OUTPUT.PUT_LINE('Last name does not exist');
     END;
    END;
    /
    show errors;

错误

PACKAGE shop_query_pkg compiled
PACKAGE BODY show_query_pkg compiled
Warning: execution completed with warning
Failed to resolve object details

Answer 1

您不能在重载过程中使用相同名称和相同数量的相同类型的参数并且包体名称也是错误的还有其他小错误

另外的第一和第二个程序参数p_firstname类型p_firstname out bb_shopper.firstname％TYPE和bb_shopper.firstname％TYPE都是字符类型（EITHER BOTH CHAR或BOTH VARCHAR2等）因此不算作不同的类型

请使用以下

CREATE OR REPLACE PACKAGE shop_query_pkg IS
      procedure shop_info(p_id1        IN bb_shopper.idshopper%TYPE,
                  p_firstname1 out bb_shopper.firstname%TYPE);
      procedure shop_info(p_id2        IN bb_shopper.lastname%TYPE,
                  p_firstname2 out bb_shopper.firstname%TYPE);
END;
/
CREATE OR REPLACE PACKAGE BODY shop_query_pkg IS
    procedure shop_info(p_id1 IN bb_shopper.idshopper%TYPE, 
                                  p_firstname1 out bb_shopper.firstname%TYPE)
               IS
        BEGIN
            SELECT firstname into p_firstname1 FROM bb_shopper WHERE idshopper = p_id1;
        EXCEPTION
        WHEN NO_DATA_FOUND 
        THEN 
            DBMS_OUTPUT.PUT_LINE('ID does not exist');
        END; -- second procedure      
    procedure shop_info(p_id2 IN bb_shopper.lastname%TYPE, 
                                  p_firstname2 out bb_shopper.firstname%TYPE)
               IS
        BEGIN
            SELECT firstname into p_firstname2 FROM bb_shopper WHERE lastname = p_id2;
        EXCEPTION
        WHEN NO_DATA_FOUND 
        THEN 
            DBMS_OUTPUT.PUT_LINE('Last name does not exist');
        END;
END;
/
show errors;

Answer 2

在APPS的不同架构中创建一个包，不要在APPS中创建同义词。

如果程序包在编译时出现错误，如果您尝试使用＆＃39;显示错误＆＃39;来查看错误消息。它将显示消息为“无法解析对象详细信息”＃39;因为APPS模式中没有包或同义词。

Answer 3

检查您尝试编译的包的包规范是否有效。我建议你再次编译包规范，然后编译包体。这解决了我的问题。
