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
