I need to show data for the top 3 zipcodes for EACH of the top 5
counties. I feel totally blocked on how to make this work properly.
Here is my code - anything you can suggest will be greatly appreciated:
SET ROWCOUNT 5
DECLARE @tblTopMarkets TABLE (StateCD CHAR(2), CountyCD CHAR(3))
INSERT INTO @tblTopMarkets
select
S.StateCD,
S.CountyCD
FROM DAPSummary_By_C ounty S
WHERE S.SaleMnYear > '01/01/2004'
GROUP BY S.StateCD, S.CountyCD Order By Sum(S.Nbr_MTG) DESC
-- the above works fine but next select produces only 3 rows;
-- I need 3 times 5 rows (how to effect a "loop")
SELECT TOP 3 -- zips in a county
D.StateCD,
D.CountyCD,
D.Zip,
"Nbr_Mtg" = Sum(Nbr_MTG)
FROM @tblTopMarkets T
LEFT JOIN GovtFHADetails D
ON T.StateCD = D.StateCD AND T.CountyCD = D.CountyCD
WHERE D.SaleMnYear > '01/01/2004'
GROUP BY D.StateCD, D.CountyCD, D.Zip
Order By Sum(Nbr_MTG) DESC 4 1357

This is a whole nicer to do in SQL 2005, where you have ranking functions,
so you can rank the rows in the query.
But now we are on SQL 2000. Being a bit tired tonight, I didn't come up
with anything better than:
SET ROWCOUNT 0 -- don't forget to reset!
CREATE TABLE #temp (ident int IDENTITY,
stateCD ...
countyCD ...
zip ...
Nbr_mtg ...)
INSERT #temp (stateCD, coutnyCD, zip, nbr_mtg)
SELECT D.StateCD, D.CountyCD, D.Zip, Sum(Nbr_MTG)
FROM @tblTopMarkets T
LEFT JOIN GovtFHADetails D
ON T.StateCD = D.StateCD AND T.CountyCD = D.CountyCD
WHERE D.SaleMnYear > '01/01/2004'
GROUP BY D.StateCD, D.CountyCD, D.Zip
GROUP BY D.StateCD, D.CountyCD, D.Zip, Sum(Nbr_MTG) DESC
SELECT a.stateCD, a.countyCD, a.zip, a.nbr_mtg
FROM #temp a
JOIN (SELECT stateCD, countyCD, zip, ident = min(ident)
FROM #temp
GROUP BY stateCD, countyCD, zip= AS b
ON a.stateCD = b.stateCD
AND a.countyCD = b.countyCD
AND a.zip = b.zip
AND a.ident < b.ident +3
ORDER BY a.stateCD, a.countyCD, a.zip, a.nbr_mtg

Thanks very much for your suggestion. I couldn't get it to work as it
was but I tried to take the idea and apply it. Came up with a new
version (same objective) but I am still stuck. I cannot get it to peel
off the top 3 rows in each county. I get 393 rows in the final
resultset where I really want only 15 rows (5 counties times top 3
zipcodes in each county). I am beginning to think I need a cursor.
Here's my SQL:
SET ROWCOUNT 5
DECLARE @tblTemp TABLE (
ident int IDENTITY,
StateCD CHAR(2),
CountyCD CHAR(3),
Zip CHAR(5),
Nbr_Mtg INT)
DECLARE @tblTopMarkets TABLE (StateCD CHAR(2), CountyCD CHAR(3))
INSERT INTO @tblTopMarkets
SELECT S.StateCD,
S.CountyCD
FROM DAPSummary_By_C ounty S
WHERE S.SaleMnYear > '01/01/2004'
GROUP BY S.StateCD, S.CountyCD Order By Sum(S.Nbr_MTG) DESC
SET ROWCOUNT 0
INSERT INTO @tblTemp (StateCD, CountyCD, Zip, Nbr_Mtg)
SELECT D.StateCD,
D.CountyCD,
D.Zip,
"Nbr_Mtg" = Sum(Nbr_MTG)
FROM @tblTopMarkets T
LEFT JOIN GovtFHADetails D
ON T.StateCD = D.StateCD AND T.CountyCD = D.CountyCD
WHERE D.SaleMnYear > '01/01/2004' AND D.NonPro IS NOT NULL
GROUP BY D.StateCD, D.CountyCD, D.Zip
Order By Sum(Nbr_MTG) DESC
DECLARE @tblByCounty TABLE (
ident int IDENTITY,
StateCD CHAR(2),
CountyCD CHAR(3),
Zip CHAR(5),
Nbr_Mtg INT,
NationalRank INT)
INSERT INTO @tblByCounty (StateCD, CountyCD, Zip, Nbr_Mtg,
NationalRank)
SELECT A.StateCD, A.CountyCD, A.Zip, A.Nbr_Mtg, A.ident AS NationalRank
FROM @tblTemp A -- this set ranks by biggest zipcodes WITHIN
each county
ORDER BY A.StateCD, A.CountyCD, A.Nbr_MTG DESC, A.Zip
SELECT A.StateCD, A.CountyCD, A.Zip, A.Nbr_Mtg, A.ident, A.NationalRank
FROM @tblByCounty A -- this set ranks by biggest zipcodes WITHIN
each county

X.Nbr_Mtg, X.NationalRank
FROM @tblByCounty X

ON A.StateCD = B.StateCD

I need to link to our database at work and update our customer shipping information (16,000 customers).
I have a list of zipcodes (570) I only want to pull customers with or without the zipcodes on the list. I've tried using IN and building a (temp) table but nothing seems to be working.
I would like to find out how to do this using query, or a SIMPLE way!! Being linked to the live database, always makes me nervous!

There is probably an incredibly simple solution for this problem, but
I can't seem to figure it out. Hopefully one of you gurus can help.
I'm was messing around with PHP today and I wrote a tiny app that asks
for your name and zipcode. If your zipcode is less than 5 characters,
it asks you too enter a zip code with the proper amount of characters.
Here's the code:
