It's probably your JOIN on shipped items producing a cross product with
your JOIN on ordered items. What happens if you take the entire
shippeditems JOIN out of your statement? Are your numbers still off?
Since your query is not using data from that table you should be able to
eliminate it
Hi there!
I have some problems with the complex MySQL join operations. In most
cases, LEFT JOIN fulfills my needs but sometimes it doesn't work in the
expected way. I'll give an example:
orders
--
- orderid
- customerid
customers
-
- id
- customername
orderitems
--
- itemid
