你是想返回动态记录集吧。测试版本:oracle 8.16企业版 参考: http://download-west.oracle.com/otndoc/oracle9i/901_doc/appdev.901/a89856/06_ora.htm#1614 http://download-west.oracle.com/otndoc/oracle9i/901_doc/appdev.901/a89856/11_dynam.htm#7875 相关问题: http://www.csdn.net/expert/Topic/306/306300.shtm http://www.csdn.net/expert/Topic/336/336154.shtm ...测试过程: 1、建立测试表 CREATE TABLE student ( id NUMBER, name VARCHAR2(30), sex VARCHAR2(10), address VARCHAR2(100), postcode VARCHAR2(10), birthday DATE, photo LONG RAW ) /2、建立带ref cursor定义的包和包体及函数: CREATE OR REPLACE package pkg_test as /* 定义ref cursor类型 不加return类型,为弱类型,允许动态sql查询, 否则为强类型,无法使用动态sql查询; */ type myrctype is ref cursor; --函数申明 function get(intID number) return myrctype; end pkg_test; /CREATE OR REPLACE package body pkg_test as --函数体 function get(intID number) return myrctype is rc myrctype; --定义ref cursor变量 sqlstr varchar2(500); begin if intID=0 then --静态测试,直接用select语句直接返回结果 open rc for select id,name,sex,address,postcode,birthday from student; else --动态sql赋值,用:w_id来申明该变量从外部获得 sqlstr := 'select id,name,sex,address,postcode,birthday from student where id=:w_id'; --动态测试,用sqlstr字符串返回结果,用using关键词传递参数 open rc for sqlstr using intid; end if; return rc; end get;end pkg_test; /3、用pl/sql块进行测试: declare w_rc pkg_test.myrctype; --定义ref cursor型变量 --定义临时变量,用于显示结果 w_id student.id%type; w_name student.name%type; w_sex student.sex%type; w_address student.address%type; w_postcode student.postcode%type; w_birthday student.birthday%type;begin --调用函数,获得记录集 w_rc := pkg_test.get(1); --fetch结果并显示 fetch w_rc into w_id,w_name,w_sex,w_address,w_postcode,w_birthday; dbms_output.put_line(w_name); end;4、测试结果: 通过。 声明:上述代码原创作者 KingSunSha (弱水三千)
你是要返回数据集吗?用存储过程也能返回。如下: 1、生成一TEST表 create table test( a number,b number); insert into test values(111,111); insert into test values(11,11); insert into test values(1,1); insert into test values(2,2); insert into test values(22,22); insert into test values(3,3); insert into test values(33,33); select * from test; 2、生成一个包 CREATE OR REPLACE PACKAGE TypeDefine AS TYPE Cursor_Test IS REF CURSOR RETURN Test%ROWTYPE; END; / 3、生成一个存储过程; CREATE OR REPLACE PROCEDURE sp_test (ia test.A%type,resultData out TypeDefine.Cursor_Test) AS BEGIN OPEN resultData FOR SELECT a,b from test; where a=ia; END; / 4、在ORACLE中执行测试: VARIABLE v REFCURSOR; EXECUTE sp_test(:v); PRINT :v;

...测试过程:
1、建立测试表
CREATE TABLE student
(
id NUMBER,
name VARCHAR2(30),
sex VARCHAR2(10),
address VARCHAR2(100),
postcode VARCHAR2(10),
birthday DATE,
photo LONG RAW
)
/2、建立带ref cursor定义的包和包体及函数:
CREATE OR REPLACE
package pkg_test as
/* 定义ref cursor类型
不加return类型,为弱类型,允许动态sql查询,
否则为强类型,无法使用动态sql查询;
*/
type myrctype is ref cursor; --函数申明
function get(intID number) return myrctype;
end pkg_test;
/CREATE OR REPLACE
package body pkg_test as
--函数体
function get(intID number) return myrctype is
rc myrctype; --定义ref cursor变量
sqlstr varchar2(500);
begin
if intID=0 then
--静态测试,直接用select语句直接返回结果
open rc for select id,name,sex,address,postcode,birthday from student;
else
--动态sql赋值,用:w_id来申明该变量从外部获得
sqlstr := 'select id,name,sex,address,postcode,birthday from student where id=:w_id';
--动态测试,用sqlstr字符串返回结果,用using关键词传递参数
open rc for sqlstr using intid;
end if; return rc;
end get;end pkg_test;
/3、用pl/sql块进行测试:
declare
w_rc pkg_test.myrctype; --定义ref cursor型变量 --定义临时变量,用于显示结果
w_id student.id%type;
w_name student.name%type;
w_sex student.sex%type;
w_address student.address%type;
w_postcode student.postcode%type;
w_birthday student.birthday%type;begin
--调用函数,获得记录集
w_rc := pkg_test.get(1); --fetch结果并显示
fetch w_rc into w_id,w_name,w_sex,w_address,w_postcode,w_birthday;
dbms_output.put_line(w_name);
end;4、测试结果:
通过。

1、生成一TEST表
create table test( a number,b number);
insert into test values(111,111);
insert into test values(11,11);
insert into test values(1,1);
insert into test values(2,2);
insert into test values(22,22);
insert into test values(3,3);
insert into test values(33,33);
select * from test;
2、生成一个包
CREATE OR REPLACE PACKAGE TypeDefine
AS
TYPE Cursor_Test IS REF CURSOR RETURN Test%ROWTYPE;
END;
/
3、生成一个存储过程;
CREATE OR REPLACE PROCEDURE sp_test
(ia test.A%type,resultData out TypeDefine.Cursor_Test)
AS
BEGIN
OPEN resultData FOR
SELECT a,b
from test;
where a=ia;
END;
/
4、在ORACLE中执行测试:
VARIABLE v REFCURSOR;
EXECUTE sp_test(:v);
PRINT :v;
