您要查找的是不是：
- Instead of, or along with, a key or natural join, you can specify a join using an explicit join condition. 您可以单独使用显式连接条件而不用键连接或自然连接,也可以与键连接或自然连接一起使用。
- A generated join condition is a join condition that is automatically created when you specify KEY JOIN or NATURAL JOIN. 生成的连接条件是您指定KEY JOIN或NATURAL JOIN时自动创建的连接条件。
- For example, you can join the employee and department tables using a natural join because they have a column name in common, the dept_id column. 例如,您可以使用自然连接来连接employee表和department表,因为这两个表具有一个共同的列名称:dept_id列。
- For this to work in a natural join of base tables, there must be at least one pair of columns with the same name, with one column from each table. 因此,要使用基表的自然连接,必须至少有一对具有相同名称的列,每个表一列。
- When you specify a NATURAL JOIN and put a join condition in an ON phrase, the result is the conjunction of the two join conditions. 在您指定了NATURAL JOIN并将连接条件放置于ON短语后,结果是两个连接条件的联合。
