    Hello @Anonymous ,

    Thanks for the question and using MS Q&A platform.

    Unfortunately, you cannot directly connect on-premise database to Azure Synapse notebooks.

    The best way to work with this is to pull the data into Azure Data Lake store, and then run your notebook on the storage account and then write it back to your on-prem servers. Synapse Pipelines should allow this, as well as Azure Data Factory.

    If your data store is located inside an on-premises network, an Azure virtual network, or Amazon Virtual Private Cloud, you need to configure a self-hosted integration runtime to connect to it.


    For more details, refer to Copy data from a SQL Server database to Azure Blob storage by using the Copy Data tool and Tutorial: How to access on-premises SQL Server from Data Factory Managed VNet using Private Endpoint.

    Hope this will help. Please let us know if any further queries.

    You can use Python Code to connect to any external database including on-premises SQL Server (like any connection you do with Python Code in application)

    For full example on using Python Code to connect Azure DATABASE you can check this thread:

    You just need to change the connection parameter to fit your server. For example in the jdbcHostname parameter you need to use the address to your server
