This is not to be confused with “USE Database”
I work in a company that has many servers, and analysts are always asking if there is a way to force the use of a particular server because we often have queries open which access multiple servers, and SSMS gets confused. Currently, the only way to unconfuse SSMS is to close and re-open things, and no one likes having to do that in the middle of productivity.
Indeed there is a way.
