Use Min function in subquery

Question

List the names names (first and last) of customers who have ordered the item with the lowest prouct price
Select CustFirstName, CustLastName
From Customer
Where (O.ProdNo= L.ProdNo*ProdNo) from SELECT MIN(ProdPrice) AS LowestPrice FROM Product;
When I run this it says SQL command not properly ended
I have four tables Orders, OrderLine, Product, Customer but I can't join product table with Orders table because product table hasn't got a foreign key
Is the where statement wrong?
Thanks

Please consider the following when you post a question.
1. New features keep coming in every oracle version so please provide Your Oracle DB Version to get the best possible answer.
You can use the following query and do a copy past of the output.
select * from v$version2. This forum has a very good Search Feature. Please use that before posting your question. Because for most of the questions
that are asked the answer is already there.
3. We dont know your DB structure or How your Data is. So you need to let us know. The best way would be to give some sample data like this.
I have the following table called sales
with sales
as
      select 1 sales_id, 1 prod_id, 1001 inv_num, 120 qty from dual
      union all
      select 2 sales_id, 1 prod_id, 1002 inv_num, 25 qty from dual
select *
  from sales4. Rather than telling what you want in words its more easier when you give your expected output.
For example in the above sales table, I want to know the total quantity and number of invoice for each product.
The output should look like this
Prod_id   sum_qty   count_inv
1         145       25. When ever you get an error message post the entire error message. With the Error Number, The message and the Line number.
6. Next thing is a very important thing to remember. Please post only well formatted code. Unformatted code is very hard to read.
Your code format gets lost when you post it in the Oracle Forum. So in order to preserve it you need to
use the {noformat}{noformat} tags.
The usage of the tag is like this.
{noformat}<place your code here>
{noformat}
