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

SQLRF54852drop_dimension::=

Semantics

SQLRF54853schema

Specify the name of the schema in which the dimension is located. If you omit schema, then Oracle Database assumes the dimension is in your own schema.

SQLRF54854dimension

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

Example

SQLRF54855Dropping a Dimension: Example This example drops the sh.customers_dim dimension:

DROP DIMENSION customers_dim;
