So we create a spatial grid index that will be used at query time.
所以我们创建一个空间网格索引，这个索引将在查询时用到。
As was explained before, the DB2 optimizer is not fully aware of all the details of the spatial grid index.
前面我们解释过，DB 2优化器不完全知道空间网格索引的细节。
To check if a spatial grid index is actually exploited during query time, you should have a look at the access plan.
为检查在查询时是否真正使用了一个空间网格索引，应该查看一下访问计划。
If all conditions are met, including the simple syntax rule, it is still not ensured that a spatial grid index is used to satisfy the query.
如果所有条件都符合，同时也符合简单的语法规则，那么还不能保证可以使用空间网格索引来满足查询。
Suqian City Gymnasium is a reinforced concrete spatial frame structure with a steel spatial grid roof located in a region of high earthquake intensity.
