use

This stored procedure is used to override the current database for a connection.

If the table being queried is in the current database, it is not necessary to specify a fully-qualified name (for example RTDB.dbo.analog) when composing Microsoft SQL against that table. Instead, you only need to specify the short name (for example analog). However, in many cases, as long as there are no collisions between the table names in the loaded databases, you can specify the short name, even when the table is not part of the current database.
