在oracle下创建一个test的账户，然后按一下步骤执行：
--创建表格 CREATE TABLE STOCK_PRICES( RIC VARCHAR(6) PRIMARY KEY, PRICE NUMBER(7,2), UPDATED DATE );
--插入数据 INSERT INTO stock_prices values(‘1111‘,1.0,SYSDATE); INSERT INTO stock_prices values(‘1112‘,2.0,SYSDATE); INSERT INTO stock_prices values(‘1113‘,3.0,SYSDATE); INSERT INTO stock_prices values(‘1114‘,4.0,SYSDATE);
--建立一个返回游标 CREATE OR REPLACE PACKAGE PKG_PUB_UTILS IS --动态游标 TYPE REFCURSOR IS REF CURSOR;END PKG_PUB_UTILS;
--创建存储过程 CREATE OR REPLACE PROCEDURE P_GET_PRICE ( AN_O_RET_CODE OUT NUMBER, AC_O_RET_MSG OUT VARCHAR2, CUR_RET OUT PKG_PUB_UTILS.REFCURSOR, AN_I_PRICE IN NUMBER ) IS BEGIN AN_O_RET_CODE := 0; AC_O_RET_MSG := ‘操作成功‘; OPEN CUR_RET FOR SELECT * FROM STOCK_PRICES WHERE PRICE<AN_I_PRICE; EXCEPTION WHEN OTHERS THEN AN_O_RET_CODE := -1; AC_O_RET_MSG := ‘错误代码:‘ || SQLCODE || CHR(13) || ‘错误信息:‘ || SQLERRM; END P_GET_PRICE;
--创建函数： F_GET_PRICECREATE OR REPLACE FUNCTION F_GET_PRICE(v_price IN NUMBER) RETURN PKG_PUB_UTILS.REFCURSOR AS stock_cursor PKG_PUB_UTILS.REFCURSOR; BEGIN OPEN stock_cursor FOR SELECT * FROM stock_prices WHERE price < v_price; RETURN stock_cursor; END;
