java使用jdbc执行Oracle存储过程实例

Oracle 创建存储过程
--建立程序包
CREATE OR REPLACE PACKAGE TESTPACKAGE AS
  TYPE TEST_CURSOR IS REF CURSOR;
end TESTPACKAGE;

--创建返回列表的存储过程
CREATE OR REPLACE PROCEDURE TESTC
(
P_CURSOR out TESTPACKAGE.TEST_CURSOR
)
IS
BEGIN
  OPEN P_CURSOR FOR
    SELECT * FROM epv_dev.eprk_notice_test;
END TESTC;
