[转贴]oracle存储过程返回记录集

//=============================================
// 定义包、及存储过程
// 请注意游标变量的声明和使用的方法
// 这里的游标是输出(out)参数
//=============================================
create or replace package audit is

-- Public type declarations, cursor variable
type outList is ref cursor;

PROCEDURE sp_audit_GetTaxpayerList(organize in varchar2, taxpayerList out outList);

end audit;

create or replace package body audit is
-- taxpayerList is cursor variable
PROCEDURE sp_audit_GetTaxpayerList(organize in varchar2, taxpayerList out outList)
is
begin
OPEN taxpayerList
FOR
select
strName , strTelephone
from "TB_PERSONINFO" a
WHERE a.organize = organize ;

end;

end audit;

//=============================================
// 下面是java 源码，从oracle存储过程读取记录集
// 注意一定要用oracle的jdbc API ( 可以从oracle网站下载 )
//=============================================
try
{
Connection conn = null;
ResultSet rs = null;

Class.forName("oracle.jdbc.driver.OracleDriver");
conn = DriverManager.getConnection("jdbc:oracle:thin:@192.168.0.1:1521:ora","net7b.com","net7b");

oracle.jdbc.OracleCallableStatement stmt = (oracle.jdbc.OracleCallableStatement)conn.prepareCall("{call
audit.sp_audit_GetTaxpayerList(?, ?)}");
stmt.setString( 1, "23201020100");
stmt.registerOutParameter( 2, oracle.jdbc.OracleTypes.CURSOR );
stmt.execute();
rs = stmt.getCursor( 2 );
for (int i = 0; rs.next();)
{
System.out.println(" ----["+ i +"]name:" + rs.getString(1) + "telephone:" + rs.getString(2));
}
}
catch (Exception ex)
{
ex.printStackTrace();
}

这个是用游标变量作为输入（in）参数的例子一部分。我不必废话，相信大家可以自己试着编写这样
的一个例子了。

PROCEDURE open_cv (generic_cv IN OUT GenericCurTyp,choice NUMBER) IS
BEGIN
IF choice = 1 THEN
OPEN generic_cv FOR SELECT * FROM emp;
ELSIF choice = 2 THEN
OPEN generic_cv FOR SELECT * FROM dept;
ELSIF choice = 3 THEN
OPEN generic_cv FOR SELECT * FROM salgrade;
END IF;
...
END;
