Simple subquery in Access
select
customer.name,
customer.address,
(select sum(order.orderamount) from order where order.customerid = customer.id) as amount
from customer
but you can do it wihout subquery:
select
customer.name,
customer.address,
sum(order.orderamount)
from order
join customer on order.customerid = customer.id
group by customer.name, customer.address

I have got a Subquery issue that I am sure has a really really simple solution but I can't figure out what it is!
Here's what I'm trying to do, I have two tables, let's say, customer and orders. The customer table obviously stores a list of individual customers and the orders table stores a list of orders placed by clients. I am trying to create a query that will return each customer's details as well as the total order amount placed by that customer. Try as I might I can't seem to be able to get this query to work as it says:
"You have written a subquery that can return more than one field without using the EXISTS reserved word in the main query's from clause."
I am trying to go with soemthing like this, please could anyone advise on what is wrong?
select customer.name, customer.address, (select sum(order.orderamount) from order, customer where order.customerid = customer.id) from customer
THanks!
