The SYSSTAT schema contains a small number of updatable views that are based on the system catalog tables.
SYSSTAT模式包含少量的基于系统编目表的可更新视图。
One set of read-only views is created under the SYSCAT schema, and a smaller set of updatable views is created under the SYSSTAT schema.
其中一组只读视图在SYSCAT模式下创建,另一组更小的可更新视图则是在SYSSTAT模式下创建的。
These updatable views allow you to update certain statistical information to investigate the performance of a hypothetical database, or to update statistics without using the RUNSTATS utility.
这些可更新的视图允许更新某些统计信息,从而研究假想数据库的性能,或者更新统计信息而不使用RUNSTATS实用程序。
