nested loop method的意思|示意

The nested loop join method is used to join the remote query result from each warehouse and the XML composite view result.

这里使用了嵌套的循环连接方法来连接来自每个仓库的远程查询结果和xml合成视图结果。

Join plan directives that force optimizer to use the designated join method to join tables in the query, either nested loop join, sort merge join, or dynamic hash join.

连接计划指示，强制优化器使用指定的连接方法来连接查询中的表，要么是嵌套循环连接、分类合并连接，要么是动态哈希连接。

In the previous section you learned about one type of access method, index scan (IXSCAN), and one type of join method, nested loop join (NLJOIN).

在之前的部分您已经了解了一种类型的访问方法，即索引扫描(IXSCAN)，和一种类型的联接方法，即嵌套循环联接(NLJOIN)。

The above example shows that sequential scan and indexes are used to do the data retrieval, and the nested-loop join method is used to join all tables.

以上示例展示了如何使用连续扫描和索引来进行数据检索，以及如何使用嵌套循环连接方法来连接所有表。

Also, the nested loop join method is used to join the source and target tables.

而且，嵌套循环联接方法用于联接源表与目标表。

This method consists of two nested loops: the first loop iterate through all the registered types.

这个方法由两个嵌套的循环组成：第一个循环遍历所有注册的类型。
