本文介绍了位图索引的一些限制条件，包括不能为全局分区索引指定BITMAP、不能在没有映射表的索引组织表上创建位图二级索引、不能同时指定UNIQUE和BITMAP以及不能为域索引指定BITMAP。
Bitmap indexes are subject to the following restrictions:
■ You cannot specify BITMAP when creating a global partitioned index.
■ You cannot create a bitmap secondary index on an index-organized table unless
the index-organized table has a mapping table associated with it.
■ You cannot specify both UNIQUE and BITMAP.
■ You cannot specify BITMAP for a domain index.[@more@]
