Problem with the connection to Azure SQL Database

Question

Hi, I am making a simple pipeline in Azure Data Factory. The source is an Oracle database hosted on VM (in ADF the connection to this database works properly. I used here a self-hosted Integration Runtime). The sink is an Azure SQL Database. In ADF the connection to Azure SQL Database also works properly (I used here Auto Resolve Integration Runtime.) The validation goes without errors. When I trigger the pipeline, it always fails with the message: "Cannot connect to SQL Database. Please contact SQL server team for further support."

I have enabled the option: "Allow azure services and resources to access this server".

The whole error:

Operation on target Copy data failed: ErrorCode=SqlFailedToConnect,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=Cannot connect to SQL Database. Please contact SQL server team for further support. Server: '----.database.windows.net', Database: '----', User: '----'. Check the linked service configuration is correct, and make sure the SQL Database firewall allows the integration runtime to access.,Source=Microsoft.DataTransfer.ClientLibrary,''Type=System.Data.SqlClient.SqlException,Message=A network-related or instance-specific error occurred while establishing a connection to SQL Server.

Could you tell me what the reason of that is? Thank You in advance.

Answer 2

Hi @Konrad Majcherczyk ,

Thank you for posting query in Microsoft Q&A Platform.

Changing Azure SQL linked service to use same selfhosted IR which you used for onprem and also changing firewall rules to allow selfhosted IR IP to access Azure SQL should solve this issue.

Hope this helps. Please let me know if any further queries.
