SQL Server data synchronization

 In the development process of SQL server database, sometimes the development library may need to synchronize the data of the formal library or the test library, so how does the SQL server synchronize the data? Synchronization, the script method is introduced here.

 

Make sure that the library you are using has established a link server to link to the corresponding official library, as shown in the figure

 

 

 

How to access the data in the official repository? The method uses [linked server name] + point + database name + point + dbo + point + table name

 

SELECT *
FROM [10.21.2.25].budget.dbo.tb_item_bind_info

 

Then if you synchronize the official database data next, it is very simple as follows

 

TRUNCATE TABLE budget.dbo.tb_item_bind_info
go

INSERT INTO budget.dbo.tb_item_bind_info
        ( bind_id ,
          item_id ,
          mflag,
          remark ,
          CREATION_DATE ,
          CREATED_BY ,
          LAST_UPDATED_BY ,
          LAST_UPDATE_DATE
        )
SELECT bind_id ,
          item_id ,
          mflag,
          remark ,
          CREATION_DATE ,
          CREATED_BY ,
          LAST_UPDATED_BY ,
          LAST_UPDATE_DATE
FROM [10.21.2.25].budget.dbo.tb_item_bind_info
go

 

The regular table in the SQL server will set a self-growing column. If it is synchronized as above, the synchronization will also be self-growing. This column may be different from the online data. If necessary, it must be the same as the online data. You need to turn on set IDENTITY_INSERT table name ON and at the same time , you need to add the auto-increment column to the insert

 

example

TRUNCATE TABLE budget.dbo.tb_item_bind_info
go

set IDENTITY_INSERT budget.dbo.tb_item_bind_info  ON
go

INSERT INTO budget.dbo.tb_item_bind_info
        ( id,
          bind_id ,
          item_id ,
          mflag,
          remark ,
          CREATION_DATE ,
          CREATED_BY ,
          LAST_UPDATED_BY ,
          LAST_UPDATE_DATE
        )
SELECT id,bind_id ,
          item_id ,
          mflag,
          remark ,
          CREATION_DATE ,
          CREATED_BY ,
          LAST_UPDATED_BY ,
          LAST_UPDATE_DATE
FROM [10.21.2.25].budget.dbo.tb_item_bind_info
go
