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?


回答1:


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.
