oracle中創(chuàng)建一個包含過程和函數(shù)的包

請問我用oracle寫了一個包，里面有函數(shù)和存儲過程，我要怎么樣能夠知道我寫的這個包是正確的呢？
驗證下不就知道了。
如果你的過程和函數(shù)都沒有語法錯誤就是對的。
包：包含表頭和BODY信息。
將你的函數(shù)和過程頭部信息放到包中定義。調用就可以直接調用包里面的定義。
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
--你的實現(xiàn)邏輯
END;
END;
函數(shù)也是一樣的。都需要在包里面定義
用SQLPLUS就可以自動生成的

如何建立oracle包，如何調用包的過程或是函數(shù)
包用于在邏輯上組合過程和函數(shù)，它由包規(guī)范和包體兩部分組成
1.創(chuàng)建包
--創(chuàng)建一個包sp_package
create?package?sp_package?is
--聲明該包有一個過程和函數(shù)，（沒有實現(xiàn)）
procedure?update_sal(name?varchar2,newsal?number);
function?annual_nicome(name?varchar2)?return?number;
end;
--創(chuàng)建包體（用于實現(xiàn)已經(jīng)聲明的函數(shù)和過程）
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;
--調用包中的內容
exec?sp_package.update_sal('name',number);
關于oracle的包
調用方法：包名.F_insert_user。
個人認為這個包意義不大，不能提高數(shù)據(jù)庫性能，反而增加了編程時的代碼量。
