?combine detailed and count in One Query?
Is it possible to combine a detailed query with its related count and sum without using any #temp tables at all?
ex. select customerID, customerName,
(select count(orderID) from tblOrder where orderDate > '01/01/2003'
and orderStatus = 'active') as countActive,
(select count(orderID) from tblOrder where orderDate > '01/01/2003'
and orderStatus = 'inactive') as countInActive
from rfCustomers
something like that? I was heard SQL2k has some new feature like this, or a UDF may be required? Currently, I have to use #temp table to get it.
thanks

Simple group by will do this.
create table tblOrder (orderId int, Orderstatus varchar(10), orderdate datetime,customerId int)
create table rfcustomer (customerId int, customername varchar(100))
insert into tblorder select 1,'active','8/1/2003',1
insert into tblorder select 2,'inactive','8/1/2003',1
insert into tblorder select 3,'active','8/1/2003',2
insert into tblorder select 4,'inactive','8/1/2003',2
insert into tblorder select 5,'inactive','8/1/2003',1
insert into tblorder select 6,'active','8/2/2003',1
insert into tblorder select 7,'inactive','8/3/2003',1
insert into tblorder select 8,'active','8/1/3003',2
insert into tblorder select 9,'inactive','8/3/2003',2
insert into tblorder select 15,'inactive','8/4/2003',1
insert into tblorder select 52,'inactive','8/1/2003',1
insert into rfcustomer select 1,'MAK'
insert into rfcustomer select 2,'Claire'
select rfcustomer.customerId,
rfcustomer.CustomerName,
count(tblorder.OrderId) as Count,
tblOrder.OrderStatus
from rfcustomer , (select * from tblorder where tblorder.orderdate > '1/1/03') as tblorder
where rfcustomer.customerID = tblorder.CustomerId
group by rfcustomer.customerId,
rfcustomer.CustomerName,
tblOrder.OrderStatus

Mak:
Based on your solution, I modified to put the group by with the (select customerID, count(*) as counting....) instead of at the end of the query.
this way, I could just add a virtual total table as I wish and finally to link them toghther.
thanks
