NAME¶
DROP_STATISTICS - remove 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. A notice is issued in this case.
name
The name (optionally schema-qualified) of the statistics
object to drop.
CASCADE
RESTRICT
These key words do not have any effect, since there are
no dependencies on statistics.
EXAMPLES¶
To destroy two statistics objects in different schemas, without failing if they don't exist:
DROP STATISTICS IF EXISTS
accounting.users_uid_creation,
public.grants_user_role;
COMPATIBILITY¶
There is no DROP STATISTICS command in the SQL standard.
