DROP TABLE — remove a table
DROP TABLE [ IF EXISTS ] name
[, ...] [ CASCADE | RESTRICT ]
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 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 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.)
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.
