DROP TABLE
PostgreSQL User's GuidePrevNextDROP TABLEName DROP TABLE
— Removes existing tables from a database
DROP TABLE table [, ...]
Inputs
table The name of an existing table or view to drop.
Outputs
DROP The message returned if the command completes successfully.
ERROR Relation "table" Does Not Exist! If the specified table or view does not exist in the database.
Description
DROP TABLE removes tables and views from the database.
Only its owner may destroy a table or view. A table
may be emptied of rows, but not destroyed, by using DELETE.
If a table being destroyed has secondary indexes on it,
they will be removed first. The removal of just a
secondary index will not affect the contents of the underlying table.
Notes
Refer to CREATE TABLE and
ALTER TABLE for information on
how to create or modify tables.
Usage
To destroy the films and
distributors tables:
DROP TABLE films, distributors
Compatibility
SQL92
SQL92 specifies some additional capabilities for DROP TABLE:
DROP TABLE table { RESTRICT | CASCADE }
RESTRICT Ensures that only a table with no dependent views or
integrity constraints can be destroyed.
CASCADE Any referencing views or integrity constraints
will also be dropped.
Tip: At present, to remove a referenced view you must drop
it explicitly.
