Cannot connect with Serverless SQL from Pipeline within same Synapse Workspace, SqlErrorNumber=18456

I am testing Synapse with a very simple setup and I wanted to execute an SQL script from within a Pipeline against a Serverless SQL database within the same synapse workspace.


However, when testing the connection, I get the following error:

Cannot connect to SQL Database. Please contact SQL server team for further support. Server: ',1433', Database: 'master', User: ''. Check the linked service configuration is correct, and make sure the SQL Database firewall allows the integration runtime to access. Login failed for user '...'., SqlErrorNumber=18456,Class=14,State=1, Activity ID: ....

Here are my network settings of the Synapse workspace:


Any ideas what I am doing wrong?

    Thanks for reaching out to Microsoft Q&A.

    Login failure error. If you are using azuread, try with a sql auth credentials and check. Firewall might not be an issue since you have allowed all.

    Thanks all for the suggestions.

    The solution in the end was to create a Linked Service that allows to connect with the Serverless SQL inside the Azure Synapse instance.
