每当尝试查询一个空间列时，DB 2加入一个转换，该转换将内部的、结构化类型的表示转换为应用程序能理解的表示。
Whenever you try to query a spatial column, DB2 injects a transformation from the internal, structured type representation to a representation that can be understood by the application.
同样地，我的一个用于将数据转换为列的灵活的程序重复了一个现有实用程序rs的功能，这个实用程序同样可以在BSD系统上找到，只不过rs更灵活，设计得更好。
Likewise, my very clever program for turning data into columns duplicates an existing utility, rs, likewise found on BSD systems except that rs is much more flexible and better designed.
