drop_table: remove a table
NAMEDROP TABLE - remove a table
DROP TABLE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
DROP TABLE always removes any indexes, rules, triggers, and constraints that exist for the target table. However, to drop a table that is referenced by a view or a foreign-key constraint of another table, CASCADE must be specified. (CASCADE will remove a dependent view entirely, but in the foreign-key case it will only remove the foreign-key constraint, not the other table entirely.)
- IF EXISTS
- Do not throw an error if the table does not exist. A notice is issued in this case.
- The name (optionally schema-qualified) of the table to drop.
- Automatically drop objects that depend on the table (such as views).
- Refuse to drop the table if any objects depend on it. This is the default.
To destroy two tables, films and distributors:
DROP TABLE films, distributors;
