I need some help please,
i am having two simple tables:
# select * from sales;
client_id | product
-----------+---------
1 | toolbox
1 | nails
2 | nuts
# select * from clients;
id | name
----+-------
1 | peter
2 | john
3 | marc
now i want to show all client name and the count of the sales in one
table like this:
# select name, count(sales.client_id) from clients, sales where
sales.client_id = clients.id group by name;
name | count
-------+-------
john | 1
peter | 2
works fine, but where is marc??? it should look like
name | count
-------+-------
john | 1
peter | 2
marc | 0
who can i make it work??? i think i know why my select statement
doesnt work, because of the where clause marc will never join this
table because the condition will never be true... but how can i do
it??
i guess its very very simple, but i just cant manage it.
thanks in advance
janning
