A similar technique is used when applying the unique filter to the outer query, with dot notation used to indicate the field by which results are to be filtered.

在对外部查询应用惟一筛选器时可使用类似的技术，点符号将用于说明筛选结果所依据的字段。

youdao

By using the for clause in the after-aggregation detail filter on a non-projected data item, the underlying query automatically projects and groups the item as the outer most column of the list.

通过在一个未投射的数据项上的after - aggregation细节过滤器中使用for子句，底层查询会自动将该项目投射并分组为列表的最外层列。

youdao

Now, accumulate both the inner and outer to generate the query at MSJOIN (6), that is, FILTER (10) and TBSCAN (9) (same as TBSCAN (7)).

现在，把inner和outer累积起来生成MSJOIN(6)上的查询，即FILTER(10)和TBSCAN(9)(与TBSCAN(7)相同)。
