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 can drop a
       table. To empty a table of  rows  without  destroying  the  table,  use
       DELETE [delete(7)] or TRUNCATE [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).

       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.
