The MSSQL database can use temporary tables, which have local and global points, which differ in name and visibility.
The names of the local temporary tables begin with a single #; they are only visible to the current session of the user, and are deleted when the user session ends, that is, the connection is disconnected.
The name of the global temporary table starts with # # and is visible to any user after it is created, and is deleted when all users referencing the table are disconnected from the server.
