根据上面在错误代码解决这个代码CREATE OR REPLACE PACKAGE video IS PROCEDURE new_member (p_lname in member.last_name%TYPE, p_fname in member.first_name%TYPE Default null, p_address in member.address%TYPE default null, p_city in member.city%TYPE default null, p_phone in member.phone%type default null); function new_rental (p_member_id in rental.member_id%TYPE, p_title_id in rental.title_id%TYPE) return DATE; function new_rental (p_member_id in rental.member_id%TYPE, p_title_id in rental.title_id%TYPE) return DATE; function return_movie (p_title_id in rental.title_id%TYPE, p_copy_id in rental.copy_id%TYPE, p_status in title_copy.status%TYPE ); END video;

在这个代码中，有一个小错误。在 return_movie 函数的参数列表最后，多了一个不必要的分号。需要将它删除，修改后的代码如下：

CREATE OR REPLACE PACKAGE video IS     
    PROCEDURE new_member     
    (p_lname in member.last_name%TYPE,      
     p_fname in member.first_name%TYPE Default null,      
     p_address in member.address%TYPE default null,      
     p_city in member.city%TYPE default null,      
     p_phone in member.phone%type default null);      
     
    FUNCTION new_rental         
    (p_member_id in rental.member_id%TYPE,          
     p_title_id in rental.title_id%TYPE)          
     RETURN DATE;     
     
    FUNCTION new_rental         
    (p_member_id in rental.member_id%TYPE,          
     p_title_id in rental.title_id%TYPE)          
     RETURN DATE;     
     
    FUNCTION return_movie         
    (p_title_id in rental.title_id%TYPE,          
     p_copy_id in rental.copy_id%TYPE,          
     p_status in title_copy.status%TYPE          
    );  
     
END video;
