这是一个缺陷吗?
在 Visio 中,我只能更改关系的一侧。
如果我想要“1-M”关系,我必须选择“识别”,但这会自动使FK变成PK,这对我来说似乎不太合适。
有同样问题的人说这是一个缺陷,所以 visio 中没有办法解决它吗?
In Visio I can only alter one side of the relationship.
If I want a "1-M" relationship, I have to choose "Identifying", but this automatically makes the FK becomes PK, which doesn't seem right to me.
Someone with the same problem said it was a flaw, so there is no way around it in visio?

确保在子表的列列表中为外键列选中“必需”。如果您这样做,您应该看到关系描述为:-II--O<-,我想这就是您想要的。
Make sure "Required" is checked for the foreign key column(s) in the column list in the child table. If you do that you should see the relationship depicted as: -II--O<-, which I guess is what you want.
