DROP STATISTICS

SQL - Language Statements

DROP STATISTICS

remove extended statistics

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.
