在实际的项目开发中我们需要通过VB(或其他语言工具)调用Oracle程序包内的存储过程返回结果集.这里以短信运营平台中的一个调用为例来说明这个过程,希望对你有所帮助.

　　一.使用SQL*Plus创建以下项目:

　　--1.建表("OW_SMP"为方案名称,下同)

　　CREATE TABLE "OW_SMP"."SM_Send_SM_List"(

　　SerialNo INT PRIMARY KEY, --序列号

　　ServiceID VARCHAR(50), --服务ID（业务类型）

　　SMContent VARCHAR(1000), --短信内容

　　SendTarget VARCHAR(20), --发送目标

　　Priority SMALLINT, --发送优先级

　　RCompleteTimeBegin DATE, --要求完成日期（开始）

　　RCompleteTimeEnd DATE, --要求完成日期（结束）

　　RCompleteHourBegin SMALLINT, --要求完成时间（开始）

　　RCompleteHourEnd SMALLINT, --要求完成时间（结束）

　　RequestTime DATE, --发送请求时间

　　RoadBy SMALLINT, --发送通道（0：GSM模块，1：短信网关）

　　SendTargetDesc VARCHAR(100), --发送目标描述

　　FeeValue FLOAT, --本条短信信息费用（单位：分）

　　Pad1 VARCHAR(50),

　　Pad2 VARCHAR(100),

　　Pad3 VARCHAR(200),

　　Pad4 VARCHAR(500),

　　Pad5 VARCHAR(1000)

　　);

　　--2.建立自增序列

　　Create sequence "OW_SMP"."SENDSNO";

　　CREATE OR REPLACE TRIGGER "OW_SMP"."BFINERT_SM_SEND" BEFORE

　　INSERT ON "SM_SEND_SM_LIST"

　　FOR EACH ROW begin

　　select SendSNo.nextval into :new.serialno from dual;

　　end;

　　--3.插入数据

　　Insert SM_Send_SM_List (SMCOntent) values('Happy New Year To Jakcy!');

　　Insert SM_Send_SM_List (SMCOntent) values('Happy New Year To Wxl!');

　　--4.建立程序包和包体

　　CREATE OR REPLACE PACKAGE "OW_SMP"."OW_SMP_PACKAGE"

　　is

　　index by binary_integer;
