Hi,
this is my first post in this forum and it feels good to be in this forum.
Here is my problem,
I've a database for a shop which has a product table and few other tables which are sub-entities of the product.
I mean this:
telescope IS-A product
book IS-A product
DVD IS-A product
now i have a primary key in product table(proid) and i have this key in each of the other sub-entities as their primary key. since i've modeled them this way, the product table contains only the common attributes and the other tables contain specific attributes for each product.

the bumpy road begins here with data insertion. how should i insert the data for a telescope for example?
inserting the data in product table is no pain, but how should i give the telescope table, the proid in the product table?
help me please,

SM

excellent first post, and congrats for modelling the supertype/subtype structure properly

you'll want the LAST_INSERT_ID function
