DROP
NAME
DROP TABLE - remove a table
SYNOPSIS
DROP TABLE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
DESCRIPTION
DROP TABLE removes tables from the database. Only its owner may destroy a
table. To empty a table of rows without destroying the table, use DELETE
[delete(5)] or TRUNCATE [truncate(l)].
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.)
PARAMETERS
IF EXISTS
Do not throw an error if the table does not exist. A notice is issued
in this case.
name The name (optionally schema-qualified) of the table to drop.
CASCADE
Automatically drop objects that depend on the table (such as views).
RESTRICT
Refuse to drop the table if any objects depend on it. This is the
default.
EXAMPLES
To destroy two tables, films and distributors:
DROP TABLE films, distributors;
COMPATIBILITY
This command conforms to the SQL standard, except that the standard only
allows one table to be dropped per command, and apart from the IF EXISTS
option, which is a PostgreSQL extension.
