When you no longer need a table, you can remove it from the database by dropping it.
(For details, search for "table" in SQL Enterprise Manager Help.)
Or
For example:
DROP TABLE authors
drops the authors table from the pubs sample database. It is recommended that you not drop tables from the pubs sample database. If you do delete a table, you can always reinstall pubs (INSTPUBS.SQL, the pubs script, is located in the SQL Server INSTALL directory).
(For details, see the DROP TABLE statement in the Microsoft SQL Server Transact-SQL Reference.)
Note You cannot drop any of the system tables in the master database or a user database.
SQL Server removes the specified table from the database, together with its contents and all the indexes and permissions associated with it. Rules or defaults bound to the table are no longer bound but are otherwise unaffected.
