JAVA调用ORACLE存储过程

ORACLE代码

--创建一个包
CREATE OR REPLACE PACKAGE ZHL  AS
 TYPE Test_CURSOR IS REF CURSOR;
end ZHL;
--创建存储过程 返回一个游标
CREATE OR REPLACE PROCEDURE ZHL_PACKAGE(c_cur out ZHL.Test_CURSOR) AS
BEGIN
  OPEN c_cur for
    select * from zhl_table;
END;

JAVA代码

import java.sql.DriverManager;
import java.sql.ResultSet;
