Excel query using SQL inner join command

I am retrieving inventory information from a Pervasive db using excel query. I need the inventory info from 2 different tables. I want the results on 1 worksheet. The product number is the common field in both tables so I use INNER JOIN to get the price for the product (Price table) and match it to the stock name and quantities (inventory table). However the results give me duplicates (sort of). I get results with each product listed on 2 rows. One row has all of the stock information from the Inventory table as well as the pricing from the Price Tables (just what I want) however there is also a second row with just the results from the inventory table and 0 for price. How do i fix this?
SELECT partnum, description, price1, wholesale, ave_cost, on_hand FROM inventory, pricing
WHERE partnum = pricepartnum

try this:

SELECT inv.partnum, inv.description, pri.price1, pri.wholesale, pri.ave_cost, inv.on_hand
FROM inventory Inv, pricing pri
WHERE inv.partnum = pri.pricepartnum and price1 <> 0

I add alias and one more condition on where.

This solves the problem but does not answer why the results returned 2 rows for every product number with one row containing a price of 0 and the other row containing the correct price

It depends on usage and maintenance of pricing table
May be rows with 0 are used to list all products available in your system. Or it could be some errors in your system that inserted rows with price 0  or some leftover from debugging...

Run this
SELECT *
FROM pricing P WHERE P.Price =0
to see all those rows.
