Structured Query Language/Drop Table< Structured Query Language
The DROP TABLE command removes the definition and all data of the named table from the database.
DROP TABLE <t1>;
The command handles the table as a whole. It will not fire any trigger. But it considers Foreign Key definitions. If any other table referes to the table to be dropped, the DROP TABLE command will fail. The Foreign Key definition must be dropped first.
As the DROP TABLE command handles the table as a whole, it is very fast.
