Hi all!
I have an Access 2000 database for the Habiat for Humanity where I work.
This is the second database I have written and it gets a bit more complex
each time... I have learned much and read much over the last few months and
have found leads to the answers to several other problems I have encountered
with a Google search of past posts/threads.
SO thank you for the help already rendered even though you didn't know!!
My problem is this I want to pull a query with just the LAST donation from
all donors (as opposed to just the "last donation")
The data is stored in two tables tblCntc and tblDonations
I can pull everything together with query called QryCntcDonation sLast and
set the "total" to Last and get ALMOST what I need.
SQL reads:
SELECT tblCntc.CntcID, tblCntc.Cntc1Fi rstName, tblCntc.Cntc1La stName,
tblCntc.CntcOrg anization, Last(tblDNDonat ions.DNDate) AS LastOfDNDate
FROM tblDNDonations INNER JOIN tblCntc ON tblDNDonations. DNID =
tblCntc.CntcID
GROUP BY tblCntc.CntcID, tblCntc.Cntc1Fi rstName, tblCntc.Cntc1La stName,
tblCntc.CntcOrg anization;
As it is written this works fine - but what I NEED are additional fields
from the tblDonations like amount, purpose, etc. WHEN I add ANYoff these
the LAST element appears to not work and the query begins to return more
than just the LAST donation from donors.
I have read several posts about the dmax or max and have tried several of
the suggestions but they don't seem to work and return either all the
donations or don't work.
ANY help will be appreciated. I have spent several hours over the last few
evenings and have not had any sucess.
Thanks
Andy
FYI: My next step is to add a volunteer scheduling component and will need a
similar query for when volunteers were last scheduled. 3 2016
I think if you have 1 query (Query1) just returning the CntcID and the
LastOfDNDate, and then create a second query with whatever information you
want. That would consist of your 2 table + Query 1 but join the 2 CntcIDs
and the LastOfDNDate to the DNDate. That should only pull information
applicable to the last donation date

FYI: My next step is to add a volunteer scheduling component and will need

as a quick test, I created tblOne
id (pk)
lastName
id lastname
1 cane
2 able
and tblTwo
id (pk) (uk)
seq (pk)
date (uk)
donation
id seq date donation
1 1 1/3/2004 8
1 2 1/4/2004 9
2 1 1/5/2004 10
2 2 1/6/2004 11
since you want the donation for the last date, I assume that every
date in tblTwo is unique ?
then I created qry2
SELECT tblTwo.id, Last(tblTwo.dat e) AS LastOfdate
FROM tblTwo
GROUP BY tblTwo.id;
id lastDate
1 1/4/2004
2 1/6/2004
then I created qry1
SELECT tblOne.lastName , qry2.LastOfdate , tblTwo.donation
FROM (tblOne INNER JOIN qry2 ON tblOne.id = qry2.id) INNER JOIN
tblTwo ON
(qry2.LastOfdat e = tblTwo.date) AND (qry2.id = tblTwo.id);
^^^^ - this is based on my assumption above
lastName lastDate donation
cane 1/4/2004 9
able 1/6/2004 11
is this what you need ?
if my assumption is incorrect, which donation amount would you want
for id 2 ?
id seq date donation
1 1 1/3/2004 8
1 2 1/4/2004 9
2 1 1/5/2004 10
2 2 1/5/2004 11

Phil & Roger,
Thanks for your help.
Phil had the right answer,[twin/dbl join] but something Roger said tipped me
off to my mistake. "I assume that every date in tblTwo is unique"
The donations table has about 900 records. When drilled down with the Last
query it returns about 350 records - one date for each donor -however what
was throwing me off was that many donors have multiple donations on the SAME
day....
Had I realized this 18 months ago I would have created a "donation date"
table with related "donated items" table... [so now I have to wrestle with
changing that data "for the long term good" or "its not that important"]
Thanks again!
Andy

Hi,
I have the sort of standard Donors/Donations DB. The twist I have is
that donations can be time, money (which are easy, because they're
additive), but then a donor can make an in-kind pledge, of say 3 chairs
and a table.
Normally, in subclassing the donation, I would end up with something
like this:
