使用VB调用Oracle程序包内的存储过程返回结果集


  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
     type tSerialNo is table of sm_send_sm_list.SerialNo%type
      index by binary_integer;

      index by binary_integer;

      index by binary_integer;
     type tPriority is table of sm_send_sm_list.Priority%type

      index by binary_integer;
     type tRequestTime is table of sm_send_sm_list.RequestTime%type
      index by binary_integer;
     type tRoadBy is table of sm_send_sm_list.RoadBy%type
      index by binary_integer;
     type tSendTargetDesc is table of sm_send_sm_list.SendTargetDesc%type

      index by binary_integer;
     type tPad5 is table of sm_send_sm_list.Pad5%type
      index by binary_integer;
     type tCount is table of number
      index by binary_integer;
  
      procedure GetSendSM
         (v_NowByMinute in Number,
