- Create a database in MS SQL server
- In Mendix, under the project tab in the file explorer open your settings.
- Open one of the configurations
-Set database type to MS SQL Server
- Set the correct name and authorisation, standard URL is localhost:1433 I believe
Now you can start your app and it should work. If there is a pop-up click on synchronize database.
Or is there a more specific problem?
I'll add a new answer so I can show it on a screenshot.
Run SQL server configuration manager.
Under network configuration see protocols for MSSQLSERVER.
Check that TC/IP is enabled. IF not right click and enable it.
Here the snapshot for your reference
