To my dearest experts,

I've searched the KB, but can't locate a basic version of what I'm looking for.  

I have a Transaction table (ActivityHist) that show's bank activity.  What I need is (hopefully) a rather simple solution.  I want to see a list of Transactions (TranNo) on a specific Date (BookDate) broken down by Customer (CustID) with a sum of activity (BaseAmt) of 10000.01 or higher.  

All data fields are in the same table, no joins and such required.

Any and all help would be greatly appreciated.

-Nick

<air code>  Let's start with this..
Declare @dt date = '2013-10-01'

SELECT CustID, TranNo, Sum(BaseAmt) as BaseAmtSum
FROM ActivityHist
GROUP BY CustID, TranNo
HAVING Sum(BaseAmt) > 10000

Open in new window

Q:  Does the transactions make up the sum, where you wish to apply the criteria of 'greater than ten grand'?

btw I wrote an article on SQL Server GROUP BY Solutions that would be a good read.

You will need a JOIN, since you have to determine the total while also listing the details.

Below is as close as I get with the info so far.  I used ABS(BaseAmt) in the SUM() so that credits/debits would not cancel each other out, as either/both are activity on the account.  If that's not correct, naturally remove the ABS() :-) .


DECLARE @BookDate date -- chg data type to to exactly match the data type on the table
DECLARE @trans_total decimal(9, 2) -- chg data type to to exactly match the data type on the table

SET @BookDate = '20131022'
SET @trans_total = 10000.01

SELECT ah.*
FROM dbo.ActivityHist ah
INNER JOIN (
    -- check for any customer that meets/exceeds the desired total of value of all trans
    SELECT CustID
    FROM dbo.ActivityHist
    WHERE
        BookDate = @BookDate
    GROUP BY CustID
    HAVING SUM(ABS(BaseAmt)) >= @trans_total
) AS ah_total ON
    ah_total.CustID = ah.CustID
WHERE
    ah.BookDate = @BookDate
ORDER BY
    ah.CustID, ah.TranNo

This was the first solution provided and it worked perfectly. Thank you!

(Sorry for the late reply... had some massive hardware / server issues that bled into multiple days... this became a low priority).
