Note also that in this example, there are only object changes in the change summary, no removals or additions.

还要注意的是，该变更摘要中只修改了一个对象，没有删除或者添加对象。

youdao

Another query against the summary table returns no data, but after the REFRESH table statement executes this time, the query runs successfully.

再次查询总结表，又是没有返回数据，但是当执行了REFRESH table语句之后，查询得以成功运行。

The only rule when creating instances of DataObjects is that no DataObject with a change summary may contain another DataObject with a change summary.

创建数据对象实例的唯一规则是，任何带更改摘要的数据对象都不能包含其他带更改摘要的数据对象。
