DROP STATISTICS

Removes extended statistics.

Synopsis

DROP STATISTICS [ IF EXISTS ] <name> [, ...] [ CASCADE | RESTRICT ]

Description

DROP STATISTICS removes statistics object(s) from the database. Only the statistics object’s owner, the schema owner, or a superuser can drop a statistics object.

Parameters

IF EXISTS : Do not throw an error if the statistics object does not exist. LightDB-A Database issues a notice in this case.

name : The name (optionally schema-qualified) of the statistics object to drop.

CASCADE RESTRICT : These key words have no effect, since there are no dependencies on statistics.

Examples

Destroy two statistics objects in different schemas, without failing if they do not exist:

DROP STATISTICS IF EXISTS
    accounting.users_uid_creation,
    public.grants_user_role;
