The first part of this tutorial presents examples of inner and outer joins.

本教程的第一部分给出了关于内部连接和外部连接的例子。

youdao

BIRT also provides a special data set called a Joint data set that allows combining existing data sets using inner and outer joins.

BIRT还提供了一个叫做联合数据集(Joint Data Set)的特殊数据集以使用内外连接来整合现存的数据集。

youdao

If you want triggers, aggregated functions, outer joins, views, and other SQL features, they are all there (something you won't get from most lightweight relational databases).

如果您想要使用触发器、聚合函数、外部联接、视图以及其他SQL功能，HSQLB都可以满足您的需要(大部分轻量级关系数据库无法做到这一点)。
