hai,
I have two tables Orders and Customers which are related by Cust_id.here i just want to know the total no of orders placed by each customer.
I used the query
select cust_name,cust_state,
(select count(*)
from orders
where orders.cust_id=customers.cust_id) as orders
from customers
order by cust_name;
the result is 'missing expression ' at subquery.
is there anything wrong with this query
please help me
