How to update SQL Server table from ADF?

问题

I need to update the Azure SQL Server table if another SQL Server table is updated.

For example: I have one Azure SQL table dbo.Azuretable, and I also have a SQL Server table dbo.sqlservertable. Both these tables are part of two different SQL Server instances, but the table schema is exactly the same.

What happens is dbo.sqlservertable updates on a daily basis. Let's say every day one row inserts in dbo.sqlservertable, I want the same row to be inserted into dbo.Azuretable as soon as dbo.sqlservertable gets updated. I want to do it in Azure if possible, or I am open to any other method as well.

What I have done so far:

I created one copy activity which replicates the changes to dbo.Azuretable whatever happened in dbo.sqlservertable. But I need to manually trigger it because I don't know when my dbo.sqlservertable gets updated. I want to automate this process.

First, you require to find inserted rows. Use except functions.

首先,您需要找到插入的行。使用 except 函数。

select * from dbo.sqlservertable
except
select * from dbo.Azuretable

然后添加到 "dbo.Azuretable"

然后添加到 "dbo.Azuretable"

WITH new_records AS (
select * from dbo.sqlservertable
except
select * from dbo.Azuretable
)

INSERT INTO dbo.Azuretable
SELECT * FROM new_records

You can use data factory or synapse pipeline for it. Pipeline->Activities->General-> Script meets your demand. After that you'll see a lightning icon named "add trigger," click and choose "new/edit." Bring your mouse to choose a trigger and click. Now, click "new." There are all schedule settings. I hope this solution helps you.

您可以使用数据工厂或 Synapse 管道来完成这项任务。管道->活动->常规-> 脚本 符合您的需求。之后,您将看到一个名为 "add trigger" 的闪电图标,点击并选择 "new/edit"。将鼠标移到触发器上并点击。现在,点击 "new"。这里有所有的调度设置。希望这个解决方案对您有帮助。

以下是翻译好的部分:

  1. 使用 Azure SQL 数据库中的数据同步功能,从 SQL Server 同步数据到 Azure SQL 数据库。
    https://learn.microsoft.com/en-us/azure/azure-sql/database/sql-data-sync-data-sql-server-sql-database?view=azuresql

  2. 您可以在 SQL Server 2017 中的表上创建触发器,在插入、更新、删除时触发,并通过触发器调用存储过程,将数据通过 PolyBase 导出到 Blob 存储。利用 ADF 管道中的 Blob 触发器来将数据从 SQL Server 同步到 Azure SQL 数据库。
    https://learn.microsoft.com/en-us/sql/relational-databases/polybase/polybase-versioned-feature-summary?view=sql-server-ver16

或者,您还可以触发一个 SQL Server 作业,其中可以包含用于生成 Blob 存储中文件的 PowerShell 逻辑,或者触发 ADF REST API 来触发管道。
示例参考:
https://datasharkx.wordpress.com/2022/10/01/event-trigger-data-sync-from-sql-server-to-synapse-via-azure-data-factory-synapse-pipeline/

英文:

There are multiple ways to sync the data :

  1. use data sync in azure sql database to sync from sql server to Azure SQL database
    https://learn.microsoft.com/en-us/azure/azure-sql/database/sql-data-sync-data-sql-server-sql-database?view=azuresql

  2. You can create a trigger on the table in SQL server 2017 on insert,update,delete

and via trigger, call a stored procedure which would export data into blob via polybase.
leverage blob trigger in adf pipeline to sync data from sql server to Azure SQL database

https://learn.microsoft.com/en-us/sql/relational-databases/polybase/polybase-versioned-feature-summary?view=sql-server-ver16

Else you can also trigger a SQL server job wherein you can have a powershell logic to generate a file in blob or trigger ADF REST API for pipeline trigger
