inner join

基本解释

J is an inner join.
J 是一个内部连接。
Since this is an inner join, this view has no rows for records that appear in wells but not in wells_pts (because they have null or invalid coordinates).
因为这是一个内联结，所以这个视图不包含出现在 wells 表中但没有出现在 wells_pts 表中的记录（因为这些记录具有空的或无效的坐标）。
Also at the time of this article?s writing, the JoinRowSetImpl class only implemented the ability to perform an inner JOIN like that showcased in this article.
同样是在本文编写之际，JoinRowSetImpl 类只实现了执行内 JOIN（也就是本文用例子展示的那种连接）的能力。
