Delete Tables (Database Engine)
You can delete (drop) a table from your database in SQL Server 2012 by using SQL Server Management Studio or Transact-SQL.
Think carefully before you delete a table. If existing queries, views, user-defined functions, stored procedures, or programs refer to that table, the deletion will make these objects invalid.

Limitations and Restrictions
You cannot drop a table that is referenced by a FOREIGN KEY constraint. The referencing FOREIGN KEY constraint or the referencing table must first be dropped. If both the referencing table and the table that holds the primary key are being dropped in the same DROP TABLE statement, the referencing table must be listed first.
When a table is dropped, rules or defaults on the table lose their binding, and any constraints or triggers associated with the table are automatically dropped. If you re-create a table, you must rebind the appropriate rules and defaults, re-create any triggers, and add all required constraints.
If you drop a table that contains a varbinary (max) column with the FILESTREAM attribute, any data stored in the file system will not be removed.
DROP TABLE and CREATE TABLE should not be executed on the same table in the same batch. Otherwise an unexpected error may occur.
Any view or stored procedure that references the dropped table must be explicitly deleted or modified to remove the reference to the table.
Requires ALTER permission on the schema to which the table belongs, CONTROL permission on the table, or membership in the db_ddladmin fixed database role.
