 To use the DELETE STORAGE MAP statement to delete a storage map for a
 relation, you must have the Rdb/VMS DELETE privilege to the relation.

 You cannot delete a storage map that refers to a relation that
 contains data.  If you attempt to do so, you will receive an error
 message.  However, you can delete the relation once the necessary
 views and constraints have been deleted and the underlying storage
 map will be deleted with the relation and its data.

 You must execute this statement in a read/write transaction.  If
 there is no active transaction and you issue this statement, Rdb/VMS
 starts a read/write transaction implicitly.

 Other users are allowed to be attached to the database when you issue
 the DELETE STORAGE MAP statement.

 The following example deletes the storage map TEST_MAP:

 RDO>   DELETE STORAGE MAP TEST_MAP.
