DROP TABLE
Removes 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 removing the table definition, use DELETE
or TRUNCATE
.
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, CASCADE
must be specified. CASCADE
removes a dependent view entirely.
Parameters
IF EXISTS
Do not throw an error if the table does not exist. Cloudberry Database issues a notice in this case.
name
The name (optionally schema-qualified) of the table to remove.
CASCADE
Automatically drop objects that depend on the table (such as views), and in turn all objects that depend on those objects.
RESTRICT
Refuse to drop the table if any objects depend on it. This is the default.
Examples
Remove the table mytable
:
DROP TABLE mytable;
Remove two tables, films
and distributors
:
DROP TABLE films, distributors;
Compatibility
DROP TABLE
conforms to the SQL standard, except that the standard allows only one table to be dropped per command. Also, the IF EXISTS
option is a Cloudberry Database extension.
