Hi,

I want to implement a functionality in a database so that a menu can hold as many drinks and as many food items as possible. I am using a Link table for this functionality.

Please have a look at the link Tables.doc file attached. There is a picture (er diagram) of part of the database.

Your help might help...

Thanks - Zahid

Hi Zahid,

you´re describing a One-to-Many relationship between Menu and Food/Drink.
So you have to insert the primary key from Menu as foreign key into both Food and Drink.

It should look something like this (see attachment).

Hope this helps.
