存储过程如何返回数据集啊

[lf43]

请问ORACLE存储过程如何返回数据集（select * from talbe数据全面返回），我要它在DELPHI里用DBGRID显示怎么做？谢谢

create or replace package pkg_test
as
type cur_test is ref cursor; -- 定義一個cursor的type
end pkg_test;
/
create or replace procedure p_test
(
v_cur out pkg_test.cur_test
)
as
v_sql varchar2(100); --
begin
v_sql := 'select a1,a2 from test';
OPEN v_cur FOR v_sql; --
exception
when others then
DBMS_OUTPUT.PUT_LINE('Error ---------------' || sqlcode || ' : ' || sqlerrm );
end p_test;
/
然后在delphi里面:
query.sql.clear;
query.sql.add('select * from pkg_test.p_test()');
query.open;
將datagrid的數據源和該query關聯即可。

SQL> select * from aa;

ID NAME
---------- --------

CREATE OR REPLACE PACKAGE pkg_test
AS
TYPE myrctype IS REF CURSOR;
END pkg_test;
/

create or replace PROCEDURE get(p_rc OUT pkg_test.myrctype)
IS
sqlstr VARCHAR2 (50);
BEGIN
sqlstr:='select * from aa';
OPEN p_rc FOR sqlstr;
END get;
/
在delphi中:
with ADOStoredProc1 do
begin
Close;
procedurename:='get';
Parameters.CreateParameter('p_id',ftstring,Pdinput,20,'1');
parameters[0].Name:='p_id';
Parameters[0].Value:='3';
execproc;
Open;
end;
