DROP DIMENSION

Purpose

Use the DROP DIMENSION statement to remove the named dimension.

This statement does not invalidate materialized views that use relationships specified in dimensions. However, requests that have been rewritten by query rewrite may be invalidated, and subsequent operations on such views may execute more slowly.

Prerequisites

The dimension must be in your own schema or you must have the DROP ANY DIMENSION system privilege to use this statement.

Syntax

drop_dimension::=

Semantics

dimension

Specify the name of the dimension you want to drop. The dimension must already exist.

Example
