I have a table (tblFees) full of fees.  the fields I am interested in are:

ID               - which is an autonumber
Account    - could be many entries in this file with the same account
FeeDate   - could be many entries associated with an account


I would like a query that returns one record for each Account.  

The ID of the oldest record (based on feedate) in the account
and the Account Number.

I can't figure out a way to get it that way.

Now, if you want all of the data associated with that earliest date, you could do:

Select * FROM yourTable
INNER JOIN (
SELECT Account, Min(FeeDate) as OldestRec
FROM yourTable
GROUP BY Account
) as AcctOld
ON yourTable.Account = AcctOld.Account
AND yourTable.FeeDate = AcctOld.OldestRec
0

If feedate is not unique, you will get multiple records.  I would include the autonumber in the query and sort descending on it and include a Top 1 to limit the number of records to 1.

Select Top 1 yourtable.* FROM yourTable
INNER JOIN (
SELECT  Account, Min(FeeDate) as OldestRec
FROM yourTable
GROUP BY Account
) as AcctOld
ON yourTable.Account = AcctOld.Account
AND yourTable.FeeDate = AcctOld.OldestRec
order By ID desc;

For my simple mind I used the query designer and broke it into two queries.  The first I called 'qryTaxRecs_Fees_getOldestFee_ForBRT_1':

SELECT tblTaxRecs_Fees.BRT, Min(tblTaxRecs_Fees.FeeDate) AS MinOfFeeDate
FROM tblTaxRecs_Fees
GROUP BY tblTaxRecs_Fees.BRT
HAVING (((tblTaxRecs_Fees.BRT)>0));

The second I called 'qryTaxRecs_Fees_GetOldestFeeForBRT_2'

SELECT  tblTaxRecs_Fees.ID, tblTaxRecs_Fees.TaxHdrID, tblTaxRecs_Fees.BRT, tblTaxRecs_Fees.FeePeriod, tblTaxRecs_Fees.FeeID, tblTaxRecs_Fees.OriginalAmt, tblTaxRecs_Fees.CurrBalanceAmt, tblTaxRecs_Fees.FeeDate, tblTaxRecs_Fees.PaymentStatusID, tblTaxRecs_Fees.Active_YN
FROM tblTaxRecs_Fees INNER JOIN qryTaxRecs_Fees_getOldestFee_ForBRT_1 ON (tblTaxRecs_Fees.BRT = qryTaxRecs_Fees_getOldestFee_ForBRT_1.BRT) AND (tblTaxRecs_Fees.FeeDate = qryTaxRecs_Fees_getOldestFee_ForBRT_1.MinOfFeeDate)
WHERE (((tblTaxRecs_Fees.BRT)>0))
ORDER BY tblTaxRecs_Fees.ID;

so far so good but as PatHartman suggested there may be multiple fees with the same date on an account/BRT.  So at this point I had almost what I wanted, excpept multiple lines for any that had the same date on multiple oldest fees.

I tried the Top 1 as suggested but ended up with only a single line in my result, not a single line for each BRT.  I tried revising query 2 usning the Top 1, here is what I tried:

SELECT TOP 1  tblTaxRecs_Fees.ID, tblTaxRecs_Fees.TaxHdrID, tblTaxRecs_Fees.BRT, tblTaxRecs_Fees.FeePeriod, tblTaxRecs_Fees.FeeID, tblTaxRecs_Fees.OriginalAmt, tblTaxRecs_Fees.CurrBalanceAmt, tblTaxRecs_Fees.FeeDate, tblTaxRecs_Fees.PaymentStatusID, tblTaxRecs_Fees.Active_YN
FROM tblTaxRecs_Fees INNER JOIN qryTaxRecs_Fees_getOldestFee_ForBRT_1 ON (tblTaxRecs_Fees.BRT = qryTaxRecs_Fees_getOldestFee_ForBRT_1.BRT) AND (tblTaxRecs_Fees.FeeDate = qryTaxRecs_Fees_getOldestFee_ForBRT_1.MinOfFeeDate)
WHERE (((tblTaxRecs_Fees.BRT)>0))
ORDER BY tblTaxRecs_Fees.ID;


Where did I go wrong
