Oracle store procedure and Function返回结果集。

Oracle下可以用refer cursor来返回一个结果集给调用者：

1. Oracle store procedure返回结果集：

create or replace procedure sp_test(v_result out sys_refcursor) is
begin
open v_result for
select 'Bryan', 100, 20, 80, 200, 180
from dual;
end;

2. Oracle Function返回一个结果集：

create or replace function fn_test return sys_refcursor
as
TYPE GenericCurTyp IS REF CURSOR;
v_result GenericCurTyp;
begin
open v_result for
select 'Bryan', 100, 20, 80, 200, 180
from dual;
return v_result;
end;

3. Java中如何得到Oracle返回的结果集：

String call= "{ call ? := fn_test()}";

ResultSet rs = null;
CallableStatement stmt = null;

stmt = conn.prepareCall();
stmt.registerOutParameter(1, OracleTypes.CURSOR );
stmt.execute();
rs = (ResultSet)stmt.getObject(1);
