Hello all,
Maybe my db strucure is poorly designed, but ...
I have a PriceLists table that contains BOTH
PriceLists Name
And
Articles Prices
I have also an Articles table.
I'd like to query the database to search displayable PriceLists name and the
corresponding prices
Here what I'm trying to do :
SELECT
N.Name, P.Price
FROM
PriceLists N,
PriceLists P
WHERE
N.Owners LIKE 'TV' ''this is specific to my app
AND
N.ParentPriceListID = '' '' to get price list name
AND
N.ID *= P.ParentPriceListID
AND
P.ParentArticleID = '123ABC'
I'd need the cursor to display 0.00 if no record found for one of the price
lists, i.e :
SOME ARTICLE NAME HERE
2005 price: 0 (not yet stored)
2004 price: 200
2003 Price: 159
But I can't make this work.
Thanks in advance for your help.
Eric
