Cross selling (one for pros)

Question

Hi,
For me, one task I have left on my site is cross-selling
products on my detail page. Cross selling, for those who dont know,
is basically offering additional products that go well with the
products they already sought up in the detail page. For instance,
if they chose a flashlight, i might also want to offer them some
batteries of the right kind.
Anyways, the detail page works fine where the right product
apears by looking at the the variable productID in the URL.
Underneath I want to make an additional recordset (I guess this is
the best way) with 6 items that fit well with this product. How do
I do this? Do I need to make additional variables? How do I link
the right cross sell items to the product above which is already
linked from the master page?
What I am basically asking is some pointers to get me in the
right direction or even some more detailed ideas.
Thanks.

That looks like you are on the right track. The relationship
looks fine, but in SQL you cannot reference the second instance of
the products table directly - you need to create an alias. An alias
in SQL is simply a virtual instance of the table.
You have a few options here and I don't recall if the DW
recordset GUI allows you to create an alias. But you should be able
to write the freehand sql directly. The SQL will look something
like:
SELECT Products.Product ID, Products_1.Product ID
FROM (Products INNER JOIN Crosssell ON Products.Product ID =
Crosssell.ProductID) INNER JOIN Products AS Products_1 ON
crosssell.crossSellProductID = Products_1.Product ID
Here we've created an alias of the Products table called
Products_1. (sidenote: your table names should be singular, not
plural. So, Products should be changed to Product)
Another option is to create a query in Access that links the
tables. Access will automatically create the alias for you if you
select a table more than once in a query. Then just reference the
Access query in your ASP page the same as you would a table.
Well, something is defenitly going right...and some stuff is
definetly still not okay :).
I think that we were successfull in creating a virtual
instance of something, when i test this sql I indeed get the two
test results that i entered in the crossell table. only, the
dreamweaver recordset now shows me two workable values:
recordset2.productID and then again recordset2.productID :). So, I
guess the productId's of both the detail page item is showing as is
the productID of the cross sell product, but necesarry stuff like
the price variable, name variable etc from the table products are
still missing which i do need.
what am i doing wrong?
