每天将数据从一个数据库中的源表传输到另一个数据库中的目标表的最佳方法

Question

What would be the best way to transfer certain number of records daily from source to destination and then remove from source?

DB - SQL server on cloud.

Answer 1

As the databases are in the same server, you can create a job that transfers the data do the other database.

Because the databases are in the same server you can easily access them, just by adding the database before the table in the query, look the test that i did:

CREATE DATABASE [_Source]
CREATE DATABASE [_Destination]

CREATE TABLE [_Source].dbo.FromTable
(
some_data varchar(10)
)

CREATE TABLE [_Destination].dbo.ToTable
(
some_data varchar(10)
)

INSERT INTO [_Source].dbo.FromTable VALUES ('PAULO')

--THE JOB WOULD BE SOMETHING LIKE THIS:

-- INSERT INTO DESTINATION GETTING THE DATA FROM THE SOURCE
INSERT INTO [_Destination].dbo.ToTable
SELECT some_data 
FROM [_Source].dbo.FromTable

-- DELETE FROM SOURCE
DELETE [_Source].dbo.FromTable
