DROP TABLE(7) PostgreSQL 9.6.6 Documentation DROP TABLE(7)
NAME
DROP_TABLE - remove a table
SYNOPSIS
DROP TABLE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
DESCRIPTION
DROP TABLE removes tables from the database. Only the table owner, the
schema owner, and superuser can drop a table. To empty a table of rows
without destroying the table, use DELETE(7) or TRUNCATE(7).
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), and in turn all objects that depend on those objects (see
Section 5.13, "Dependency Tracking", in the documentation).
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.
