在SQLServer2000中用链接数据库方式向Oracle8.17写记录的Trigger

　　
创建链接数据库方式的步骤在这里不重复说明,很多地方都有资料!

CREATE TRIGGER TransferMTMessage ON [dbo].[T_DWS_MT_Message]
FOR INSERT
AS

    -- 必须设置这个选项目,否则出现 OLE DB 错误跟踪
    --［OLE/DB Provider 'MSDAORA' ITransactionLocal::StartTransaction returned 0x8004d013: ISOLEVEL=4096
    --解决异构服务器的触发器参考:http://support.microsoft.com/default.ASPx?scid=kb;EN-US;280106
    SET XACT_ABORT ON

    Declare @Seq int
    Declare @LinkID varchar(20)
    Declare @Content varchar(140)
    Declare @Mobile varchar(20)

    --Step1: 从Oracle数据库获取一个序列的nextval
    Select @Seq=(Select * from openquery(hnoracle,'Select Seq.nextval From dual'))

    --Step2: 获取新插入的数据
    Select @LinkID=LinkID From INSERTED
    Select @Content=SMS_Content From INSERTED
    Select @Mobile=MT_Mobile From INSERTED

    --Step3:将数据通过链接数据库写进Oracle数据库
    INSERT INTO [hnoracle]..[HAILINE].[MTMESSAGE](MTMSGID,MTMOBILE,CONTENT,LINKID,STATUS,SENDTIME,SPFLAG)
       Values(@Seq, @Mobile, @Content, @LinkID,0,NULL,NULL)

    --Step4:删除本地SQLServer下行信息
    Delete From T_DWS_MT_Message Where ID IN( Select ID From INSERTED)

Return
