Creating a Linked Server in Azure SQL Managed Instance to Azure SQL Database


-> Create a linked server to Azure SQL Database jbsqldbserver in Azure SQL Managed Instance jbmi-sql01.

-> Azure SQL Managed instance and Azure SQL Database are on different Resource group.

-> Azure SQL Database will have “Deny public network access” set to Yes.

-> Before creating a linked server in Azure SQL Managed Instance. I tried connecting to Azure SQL database using SQL Server management studio and got below error,

Cannot connect to

Reason: An instance-specific error occurred while establishing a connection to SQL Server. Connection was denied since Deny Public Network Access is set to Yes ( To connect to this server, use the Private Endpoint from inside your virtual network ( (.Net SqlClient Data Provider)

For help, click:

Server Name:
Error Number: 47073
Severity: 14
State: 1
Line Number: 65536

-> It seems like the private endpoint is not configured correctly. I followed below procedure to get it created properly,

-> Opened the required Azure SQL Database from Azure portal and clicked on “Firewalls and virtual networks”, Clicked on “Create Private Endpoint”.

-> Complete the “Basics” tab as below,

-> Complete the “Resource” tab,

-> Complete the “Configuration” tab. Select the Vnet related to Azure SQL Managed instance,

-> It is to be noted that you cannot select the subnet used by Azure SQL managed instance, you will receive below error when you do that.

The selected subnet ‘MI’ has a delegation and cannot be used with a private endpoint.

-> Select a different subnet for MI and proceed further,

-> Complete the “Tags” tab and create the private endpoint,

-> Now I am able to connect to the Azure SQL Database,

-> Try creating Linked server now,

-> Right click created linked server and click on “test connection” and it connects just fine.
