You need to GROUP BY those fields NOT in the aggregate function. Like:
SELECT f.id,f.name,sum(p.price)
FROM fruit f
left join purchase p on f.id = p.fruit
where p.price is not null
group by f.id,f.name;
1, 'Apples', 2
2, 'Grapes', 6.5
4, 'Kiwis', 4

One more guess:
Try explicitly aliasing the fields of interest and using those aliases
exclusively throughout the rest of the expression.
SELECT
p.pk_ProductID as pid,
p.Description as dsc,
SUM(i.Quantity) as totl
FROM invoice_invoicelines_Product p
JOIN invoice_InvoiceLines i ON pid = i.fk_Prod

Yeah I tried that - actually the SUM I need is on the
I'm not at a terminal but have you tried grouping by p.pk_ProductID instead
of i.fk...? It is the actual value you are selecting as well as being on
the primary table in the query.
