## ALTER STATISTICS

ALTER STATISTICS — change the definition of an extended statistics object

## Synopsis

    ALTER STATISTICS name OWNER TO { new_owner | CURRENT_USER | SESSION_USER }
    ALTER STATISTICS name RENAME TO new_name
    ALTER STATISTICS name SET SCHEMA new_schema

## Description

`ALTER STATISTICS` changes the parameters of an existing extended statistics object. Any parameters not specifically set in the `ALTER STATISTICS` command retain their prior settings.

You must own the statistics object to use `ALTER STATISTICS`. To change a statistics object's schema, you must also have `CREATE` privilege on the new schema. To alter the owner, you must also be a direct or indirect member of the new owning role, and that role must have `CREATE` privilege on the statistics object's schema. (These restrictions enforce that altering the owner doesn't do anything you couldn't do by dropping and recreating the statistics object. However, a superuser can alter ownership of any statistics object anyway.)

## Parameters

`name`

  The name (optionally schema-qualified) of the statistics object to be altered.

`new_owner`

  The user name of the new owner of the statistics object.

`new_name`

  The new name for the statistics object.

`new_schema`

  The new schema for the statistics object.

## Compatibility

There is no `ALTER STATISTICS` command in the SQL standard.
