NAMEDROP TABLE − remove a table

---

SYNOPSISDROP TABLE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]

---

DESCRIPTIONDROP 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.)

---

PARAMETERSIF 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.

---

EXAMPLESTo destroy two tables, films and distributors: DROP TABLE films, distributors;

---

COMPATIBILITYThis 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.

---

SEE ALSOALTER TABLE [alter_table(7)], CREATE TABLE [create_table(7)] 0
