Help

I've got a list of products
ProdID......Product
-------------------
1...........Mountain bike
2...........road bus
3...........Mountain Car

then I used term extraction to make a table of all the nouns:
TermID.....Term
----------------
1..........mountain
2..........bike
3..........road
4..........bus
5..........car

Now I want to index the two tables together to find out which term came from which product. Result will be like this:
TermID......ProdID
------------------
1...........1
1...........3
2...........1
3...........2
4...........2
5...........3

So what's wrong with this SQL?

SELECT A.TermID, B.ProdID
FROM tblProduct B
CROSS JOIN tblTerm A
WHERE CONTAINS(B.Product, A.Term)

Thanks

Jason

inner join tblTerm t on p.Product like '%' + t.Term + '%'
[/code]

Thanks for your reply. I'm sure I'll use your ideas later.
Sorry to be awkward but I wanted to use 'CONTAINS' predicate because it does Word breaking, stemming and thesaurus replacemsnts.

When I run the SQL

1 SELECT A.TermID, B.ProdID
2 FROM tblProduct B
3 CROSS JOIN tblTerm A
4 WHERE CONTAINS(B.Product, A.Term)

I get Error Line 4 Incorrect Sytax near 'A'
I'm not sure if I'm allowed to use a field as the second parameter. All the examples I see use a variable.

Does anyone have experience with this?

Thanks

Jason
