Contents Aster SQL and Function Reference

Aster Data proprietary and confidential DROP TABLE

However, it is not necessary to remove role memberships involving the role; DROP ROLE automatically revokes any memberships of the target role in other roles, and of other users and roles in the target role. The other users and roles are not dropped nor otherwise affected.

Compatibility

The SQL standard defines DROP ROLE , but it allows only one role to be dropped at a time, and it specifies different privilege requirements than Aster Database uses.

DROP SCHEMA

Synopsis

Parameters

IF EXISTS Do not throw an error if the schema does not exist. A notice is issued in this case.

name The name of a schema.

CASCADE Automatically drop objects (tables, functions, etc.) that are contained in the schema.

RESTRICT Refuse to drop the schema if it contains any objects. This is the default.
