sql server 2008 数据实时同步到postgres

1.下载安装postgres odbc driver

https://www.postgresql.org/ftp/odbc/versions/msi/

2.创建odbc 服务器

创建sqlserver 链接服务器
 

USE [Card3500]
exec sp_addlinkedserver 
 @server='postgres11',       --ODBC里面data source name
 @srvproduct='postgres',    --自己随便
 @provider='MSDASQL',    --固定这个
 @datasrc=NULL,
 @location=NULL,
 @provstr='DRIVER={PostgreSQL ANSI};SERVER=127.0.0.1;DATABASE=postgres;UID=postgres;PORT=5432;',   
 @catalog = NULL
 GO
 
 
 USE [Card3500]
---创建连接postgres数据库的账号及密码
exec sp_addlinkedsrvlogin
@rmtsrvname='postgres11',----ODBC里面data source name
@useself='false',
@rmtuser='postgres',---postgres账号
@rmtpassword='';--postgres账号其密码
GO

 

--测试是否可以访问mysql数据库中的表

select * from openquery(postgres11,'SELECT * FROM tb; ')

 

-----建立允许远程访问连接操作

USE [Card3500]
GO
EXEC Card3500.dbo.sp_serveroption @server=N'postgres11',@optname=N'rpc out',@optvalue=N'TRUE'
GO
EXEC Card3500.dbo.sp_serveroption @server=N'postgres11',@optname=N'remote proc transaction promotion',@optvalue=N'false'
GO

 

  
--建立LOOPBACK 服务器链接 （回路）

USE [Card3500]
GO
EXEC sp_addlinkedserver @server=N'loopback1',@srvproduct=N' ',@provider=N'SQLNCLI',
@datasrc=@@SERVERNAME
go

 

--设置服务器链接选项，阻止SQL Server 由于远过程调用而将本地事务提升为分布事务（重点）

USE [Card3500]
GO
EXEC Card3500.dbo.sp_serveroption @server=N'loopback1',@optname=N'rpc out',@optvalue=N'TRUE'
GO
EXEC Card3500.dbo.sp_serveroption @server=N'loopback1',@optname=N'remote proc transaction promotion',@optvalue=N'false'
GO

 

---编写触发器和存储过程
--insert

USE [Card3500]
GO
CREATE TRIGGER TR_INSERT_pg_TB ON  Card3500.DBO.TB
FOR INSERT
AS
DECLARE @ID INT,@QTY INT
SELECT @ID=ID,@QTY=QTY FROM INSERTED;
BEGIN
    EXEC loopback1.Card3500.dbo.sp_insert_pg_tb @id,@qty;
END
go


USE [Card3500]
GO
CREATE PROCEDURE SP_INSERT_pg_tb
@ID INT,
@QTY INT
AS
BEGIN
    SET NOCOUNT ON
    INSERT OPENQUERY(postgres11,'select * from tb')(id,qty) values (@id,@qty);
    SET NOCOUNT OFF
END
GO

 

 
---update

USE [Card3500]
GO
CREATE TRIGGER TR_UPDATE_pg_TB ON Card3500.DBO.TB
FOR UPDATE
AS
DECLARE @ID INT,@QTY INT
SELECT @ID=ID,@QTY=QTY FROM INSERTED;
BEGIN
    EXEC loopback1.Card3500.dbo.sp_update_pg_tb @id,@qty;
END
GO

USE [Card3500]
GO
CREATE PROCEDURE SP_UPDATE_pg_tb
@ID INT,
@QTY INT
AS
BEGIN
    SET NOCOUNT ON
    UPDATE OPENQUERY(postgres11,'select * from tb') SET qty=@qty WHERE id=@id
    SET NOCOUNT OFF
END
go

 

 
--delete

USE [Card3500]
GO
CREATE TRIGGER TR_DELETE_pg_TB ON Card3500.DBO.TB
FOR DELETE
AS
DECLARE @ID INT
SELECT @ID=ID FROM DELETED;
BEGIN
    EXEC loopback1.Card3500.dbo.sp_DELETE_pg_tb @id;
END
go

USE [Card3500]
GO 
CREATE PROCEDURE SP_DELETE_pg_tb
@ID INT
AS
BEGIN
    SET NOCOUNT ON
    DELETE OPENQUERY(postgres11,'select * from tb') WHERE id=@id
    SET NOCOUNT OFF
END
go
