验证下不就知道了。
如果你的过程和函数都没有语法错误就是对的。
包：包含表头和BODY信息。
将你的函数和过程头部信息放到包中定义。调用就可以直接调用包里面的定义。
比如：
包：你的包名a.spc
CREATE OR REPLACE PACKAGE a
IS
PROCEDURE CREATE_AE_OUT_FILE (p_gr_hdr_id IN varchar) ;
END;
body:
CREATE OR REPLACE PACKAGE BODY a
IS
PROCEDURE CREATE_AE_OUT_FILE(p_gr_hdr_id IN varchar)
IS
v_gr_hdr_id cosgx.cos_gr_hdr.gr_hdr_id%type;
vfile varchar2(200);
BEGIN
--你的实现逻辑
END;
END;
函数也是一样的。都需要在包里面定义
用SQLPLUS就可以自动生成的

包用于在逻辑上组合过程和函数，它由包规范和包体两部分组成
1.创建包
--创建一个包sp_package
create package sp_package is
--声明该包有一个过程和函数，（没有实现）
procedure update_sal(name varchar2,newsal number);
function annual_nicome(name varchar2) return number;
end;
--创建包体（用于实现已经声明的函数和过程）
create package body sp_package is
procedure update_sal(name varchar2,newsal number)
is
BEGIN
UPDATE emp
SET sal = newsal
WHERE ename = name;
END;
function annual_income(name varchar2)
return number is
annual_salary number;
BEGIN
SELECT sal * 12 + Nvl(comm,0)
INTO annual_salary
FROM emp
WHERE ename = name;
RETURN annual_salary;
END;
end;
--调用包中的内容
exec sp_package.update_sal('name',number);
调用方法：包名.F_insert_user。
个人认为这个包意义不大，不能提高数据库性能，反而增加了编程时的代码量。
