包和程序编译

Question

挣扎了一个多小时......为什么不编译？

身体编译罚款：

create or replace package body "PKG_CUSTOMER" is 

PROCEDURE Create_Customer 
( pr_customer_id customer.Customer_id%type, 
     pr_country customer.country%type, 
     pr_first_name customer.first_name%type, 
     pr_last_name customer.last_name%type, 
     pr_birth_date customer.birth_date%type, 
     pr_customer_type customer.customer_type%type, 
     pr_address customer.address%type) 

    IS 
    BEGIN 
     INSERT INTO customer (Customer_ID,Country,First_Name,Last_Name,Birth_Date,Customer_Type,Address) 
     VALUES(pr_customer_id, pr_country, pr_first_name, pr_last_name, pr_birth_date, pr_customer_type, pr_address); 
    END Create_Customer; 


    PROCEDURE Delete_Customer(pr_customer_id customer.customer_id%type) IS 
    BEGIN 
    DELETE FROM order_line WHERE fk1_order_id IN (SELECT order_id FROM placed_order WHERE fk1_customer_id = pr_customer_id); 
    DELETE FROM placed_order WHERE fk1_customer_id = pr_customer_id; 
    DELETE FROM customer WHERE customer_id = pr_customer_id; 
    END Delete_Customer; 


end "PKG_CUSTOMER";​ 

，但是这些规范将无法编译：

create or replace package PKG_CUSTOMER as 

Procedure CREATE_CUSTOMER; 
Procedure DELETE_CUSTOMER; 

end;​ 

我收到此错误：

Compilation failed,line 3 (21:20:46) 
PLS-00323: subprogram or cursor 'CREATE_CUSTOMER' is declared in a package specification and must be defined in the package bodyCompilation failed,line 4 (21:20:46) 
PLS-00323: subprogram or cursor 'DELETE_CUSTOMER' is declared in a package specification and must be defined in the package body 

我使用Oracle APEX 。

包规范必须提供您要公开的过程的完整规范。包括参数。假设你想两个你在提供给包的外部用户的包中声明的程序

create or replace package PKG_CUSTOMER 
as 
    Procedure CREATE_CUSTOMER( 
     pr_customer_id customer.Customer_id%type, 
     pr_country customer.country%type, 
     pr_first_name customer.first_name%type, 
     pr_last_name customer.last_name%type, 
     pr_birth_date customer.birth_date%type, 
     pr_customer_type customer.customer_type%type, 
     pr_address customer.address%type); 
    Procedure DELETE_CUSTOMER(pr_customer_id customer.customer_id%type); 
end;​ 

如果你的目的是要声明一个CREATE_CUSTOMER和DELETE_CUSTOMER过程，每一个接受0参数，你会需要在包体中实现这些过程。
