Help with SQL Query

Dear group,
I need to create a stored procedure to return some data. The trick is the
data needs to be AGGREGATED with a SUM of commissions against each line for
each broker...
I have a table (TRADE) with the following data:
trade_id (PK), broker_id, tradeType_id, commission_amount, datestamp
1, 1, 1, 150, 13/06/2006
2, 2, 1, 100, 13/06/2006
3, 1, 1, 75, 14/06/2006
4, 1, 2, 165, 14/06/2006
5, 3, 1, 33.50, 14/06/2006
I want to display (for a DataTable to be used in a Crystal Report) a grid
where the headers will be:
Broker ID, Daily Total (where tradeType_id = 1), Daily Total (tradeType_id =
2), Sum Daily Total, Monthly Total (where tradeType_id = 1), Monthly Total
(where tradeType_id = 2), Sum Monthly Total.
So that the query, when run on (14/06/2006), will look like:
1, 75, 165, 240, 225, 165, 190
2, null, null, null, 100, null, 100
3, 33.50, null, 33.50, 33.50, null, 33.50
The concept here is that I have a table which contains trades that a broker
has made. Each trade has a commission_amount column and a datestamp. I need
to be able to produce a report which has daily totals for different trade
types, but where the data is AGGREGATED by broker_id. All the SQL I've been
coming up with has been a total mess.
Can anyone assist with the above problem?
Many thanks!
MikeLiddle,
I think the trickiest thing here is the grouping. Is the monthly
total the running total since the first of the month, or just the sum
or trade type 2 records for a broker on a given day?
You can pretty easily group by date, broker id, and trade type.
SELECT broker_id, tradetype_id, datestamp, SUM(commission_amount) AS
sumcom
FROM TRADE
GROUP BY broker_id, tradetype_id, datestamp
but the most straightforward way to get it into the format you want is
to do two subqueries and join them back together. But, what that looks
like will depend on whether you're looking for a running total or not.

There are only four aggregated calculated fields, those are the daily totals
for trade_Type 1 and 2 and the monthly totals for trade_Type 1 and 2. The
sum is just an addition of those two fields and can be calculated easily by
hand.

Cheers, Jon - that's close, but not quite right. I'm looking for a distinct
group, so that if there are only 2 broker_id's, there will be only two rows
and the SUM() data will be aggregated on those rows.
Thanks!sql
