Help with accessing data from a webform please...

Ok,
I have a web app that calls several very complex (at least to me) sql
queries like this for example:
SELECT t1.MemberId, t1.PeriodID,
SUM(CASE WHEN t2.amountTypeId = 7 THEN t2.amount WHEN
t2.amountTypeId = 23 THEN -t2.amount END) AS Purchase,
SUM(CASE WHEN t2.amountTypeId = 8 THEN t2.amount WHEN
t2.amountTypeId = 24 THEN -t2.amount END) AS Matrix,
SUM(CASE WHEN t2.amountTypeId = 20 THEN t2.amount WHEN
t2.amountTypeId = 21 THEN -t2.amount END) AS QualiFly,
SUM(CASE WHEN t2.amountTypeId = 9 THEN t2.amount
WHEN t2.amountTypeId = 25 THEN -t2.amount END) AS Dist,
SUM(CASE WHEN t2.amountTypeId = 10 THEN t2.amount WHEN
t2.amountTypeId = 26 THEN -t2.amount END) AS SM,
SUM(CASE WHEN t2.amountTypeId = 11 THEN t2.amount
WHEN t2.amountTypeId = 27 THEN -t2.amount END) AS BreakAway,
SUM(CASE WHEN t2.amountTypeId = 13 THEN t2.amount WHEN
t2.amountTypeId = 14 THEN -t2.amount END) AS Transfer,
SUM(CASE WHEN t2.amountTypeId = 28 THEN t2.amount WHEN
t2.amountTypeId = 15 THEN -t2.amount END) AS Spent
FROM tblTravelDetail t1 INNER JOIN
tblTravelDetailAmount t2 ON t1.TravelDetailId =
t2.TravelDetailId INNER JOIN
tblTravelDetail t3 ON t2.TravelDetailId =
t3.TravelDetailId INNER JOIN
tblTravelDetailMember t4 ON t3.TravelDetailId =
t4.TravelDetailId INNER JOIN
tblTravelEvent t5 ON t1.TravelEventId =
t5.TravelEventId INNER JOIN
amount_type t6 ON t2.amountTypeId =
t6.amount_type_id
WHERE (t1.MemberId = 12391) AND (t2.amount <> 0)
GROUP BY t1.MemberId, t1.PeriodID...
It is so slow on our very fast servers. Would an XML connection with
the "SQL XML Support in IIS" be an option? How can I get this view to
be faster for users to get over the net?
Thanks for any help,
Trinttrint
Have you defined any indexes on the table?
Have you seen an execution plan of the query?

tables are created by another department, but I have exported all of
them as 'copies' to my local machine for my c# app development. I am
willing to go for it though and then present this, if faster, to my
boss to get the changes in the real instances of SQL Server. I will
research on how to do this now.
Any help on making this faster (or easier) is appreciated.
Thanks,

Help with @@Rowcount

I am writing a vb.net application that calls a stored procedure and need some
help.
I am writting the procedure to check if multiple records exists and the only
way I can figure it out is to use @.@.RowCount, but can't get the right result,
please help.
What I have now is
if exists(select c_driver from cartons where orderid = @.orderid and
@.@.Rowcount = 1)
update...
I tried using the following but got an error in my vb application becuase
the Procedure was returning rows
select c_driver from cartons where orderid = @.orderid
if @.@.Rowcount = 1
update...
Is there any way to use the above query without returning rows to VB?
Is there a way to write an exists to query @.@.Rowcount?What are you querying @.@.ROWCOUNT for? @.@.ROWCOUNT returns the rowcount of
the last operation... I have a feeling you really want:
if (select COUNT(*) from cartons where orderid = @.orderid) = 1
update ...

UPDATE cartons SET

WHERE orderid = @.orderid
IF (@.@.ROWCOUNT = 0)
BEGIN
INSERT INTO cartons (...) VALUES (...)
END
Hope this helps.

what I need to do is determin is if a single driver is assigned to multiple
cartons within an order. for Instance say driver #1 was assigned to Carton
100 and driver #24 was assigned to Carton 101 and carton 102. All 3 of these
cartons are in Order #1000
Order# Carton# Driver#
1000 100 1
1000 101 24
1000 102 24
What I need to get to is this without the select (becuase doing it this way
returns an error in my vb.net application because the select wants to return
rows)
select c_driver from Cartons where orderid = @.orderid
if @.@.RowCount = 1
--Only one driver exists for this order
Update orders set oDriver = (select distinct c_driver from cartons
where orderid = @.orderid)
if @.@.RowCount > 1
-- Multiple Driver exists for this Order

why this won't work for you:
if (select COUNT(*) from cartons where orderid = @.orderid) = 1
BEGIN
Update orders set oDriver = (select distinct c_driver from cartons
where orderid = @.orderid)
END
ELSE
BEGIN
-- do something else...

... Given that, however, I should ask why you're updating your orders table
with the driver from the cartons table? Why denormalize your data like
that?

only update when all cartons in the orders have the same driver#.
I left out the DISTINCT in my example it should be:
select DISTINCT c_driver from Cartons where orderid = @.orderid
If all drivers are the same for the cartons in the Order I should have 1
row, if there a seperate drivers I should have more than 1 row
The way the db is set up is to have one row for an order in the Orders
Table, ? Rows in Cartons table joined together on Orders.orderid =Cartons.Orderid based on the #of cartons shipped with the order. All of the
pricing and driver commissions are based on the total $'s charged from the
Orders table. So I need to update the orders table with the correct driver
information, but only if the driver is the same. Little round about I know.

Rather than storing the data in two places (which has data integrity
implications), have you considered creating a view that will return the data
in the way you need it for reporting?
