--procedure返回記錄集：
----------------------聲明一個Package--------------
CREATE OR REPLACE PACKAGE pkg_test
AS
TYPEmyrctypeIS REF CURSOR;

PROCEDURE get_r(p_id NUMBER,p_rc OUT myrctype); --Package中聲明名為get 的Procedure(只有接口沒內(nèi)容)
END pkg_test;

-----------------聲明Package Body，即上面Package中的內(nèi)容，包括Procedure get---------------------
CREATE OR REPLACE PACKAGE BODY pkg_test
AS
PROCEDURE get_r(p_id NUMBER,p_rc OUT myrctype)
IS
sqlstr VARCHAR2 (500);
BEGIN
IF p_id = 0 THEN
OPEN p_rc FOR
SELECT ID, NAME, sex, address, postcode, birthday
FROM student;
ELSE
sqlstr :=
'select id,name,sex,address,postcode,birthday
from student where id=:w_id'; --w_id是個參數(shù)，
--以下 p_rc是個REF CURSOR游標(biāo)類型，而且是OUT型參數(shù)，即可返回一個記錄集了。USING p_id就是替換上面SQL中:w_id值拉:)
OPEN p_rc FOR sqlstr USING p_id;　
END IF;
END get;
END pkg_test;

--function返回記錄集的例子，原理和上面相同，而是用function的return值來返回記錄集。

CREATE OR REPLACE
package pkg_test as

type myrctype is ref cursor;
function get_r(intID number) return myrctype;
end pkg_test;
/
CREATE OR REPLACE
package body pkg_test as
--函數(shù)體
function get_r(intID number) return myrctype is
rc myrctype; --定義ref cursor變量
sqlstr varchar2(500);
begin
if intID=0 then

--靜態(tài)測試，直接用select語句直接返回結(jié)果
open rc for select id,name,sex,address,postcode,birthday from student;
else
--動態(tài)sql賦值，用:w_id來申明該變量從外部獲得
sqlstr := 'select id,name,sex,address,postcode,birthday from student where id=:w_id';
--動態(tài)測試，用sqlstr字符串返回結(jié)果，用using關(guān)鍵詞傳遞參數(shù)
open rc for sqlstr using intid;
