Using JoinRowSet lingo, our JOIN operation was performed using a match column of DEPTID.

在使用JoinRowSet lingo时，JOIN操作是通过匹配列deptid来执行的。

youdao

As you can see, I have specified a match column of DEPTID for both the employees and departments objects.

您可以看到，对于employees和departments对象，我都指定了匹配列DEPTID。

youdao

Similarly, we do not see a row containing the DEPTID named TRA since no employee in the employee table had a DEPTID of TRA.

类似地，我们也没有看到包含名为TRA的DEPTID的行，因为在employee表中没有DEPTID为TRA的雇员。
