When setting up a Data Source connection to Azure SQL Database in Information Designer, you might get this error message when trying to expand the database:
InformationModelException at Spotfire.Dxp.Data:
Error retrieving metadata: USE statement is not supported to switch between databases. Use a new connection to connect to a different database. (HRESULT: 80131500)
...
If the account you are using has one of the databases set as default, you should be able to expand that database, but not the others.
