I'm more of an hit and try guy and do good only with a data set available.
Still I think making a little change might do the trick.
SELECT DISTINCT
p.productid,
pd.name
FROM menu_product as p
INNER JOIN menu as m ON (m.menuid = p.menuid AND m.name = '')
INNER JOIN produ
I have a MySQL database with a menu table and a product table linked to
the menus *(each product can be linked to more than menu row)* and the
menus are nested.
The query is that when a user clicks on a menu entry then all products
linked to that entry *(there may be none)* will get displayed
