DROP TABLE
SQL - Language Statements
DROP TABLE
remove a table
DROP TABLE
DROP TABLE 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.
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
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.
