If there is a database by the name StudentMarks in MongoDB then you can use use StudentMarks command to switch that database and start working on this database. But let’s assume that there is no database by the name StudentMarks in MongoDB. In this case if you still prefer use StudentMarks command than can be still OK and create the database and switch to it or would this command cause an error? Explain what happens in both scenarios?
