I need to know how to return just the top 5 DUs (Based on sum of cases lost)
for each Code desc. Below is my current SQL that returns back all records for
all CodeDesc

Please help? Thanks!

use the TOP VALUES predicate.

Try this --
SELECT Q.DU, Q.CasesLost, (SELECT COUNT(*) FROM [(0005a1)InternalDrilldown
- HPCStockAvail] Q1
WHERE Q1.[DU] = Q.[DU]
AND Q1.[CasesLost] >= Q.[CasesLost]) AS Rank
FROM [(0005a1)InternalDrilldown - HPCStockAvail] AS Q
WHERE ((((SELECT COUNT(*) FROM [(0005a1)InternalDrilldown - HPCStockAvail] Q1
WHERE Q1.[DU] = Q.[DU]
AND Q1.[CasesLost] >= Q.[CasesLost]))<=5))
ORDER BY Q.DU, Q.CasesLost DESC;

What does the Q represent? Do I substitute it for the table name?

I pasted the whole string (as is) into my current SQL, right before the
"FROM" and I got the error message: "The SELECT statement includes a reserved
word or an argument name that is misspelled or missing, or the punctuation is
incorrect"

Sorry, i'm new at SQL

Thanks. I've tried that before, but all it does is return the top 5 values
for the whole record set. I need it to be the top 5 (or less) values of each
subcategory in the record set.

Never mind. Please disregard the post above - I just needed my coffee before
attempting to dissect any SQL strings!

The reason why the error message popped up is because Q1 was never defined -
the "AS" was missing. Once i popped that in, it runs fine...although
extremely slowly.

Thanks for your help!

To increase speed, you can try:


SELECT Q.du, Q.casesLost
FROM [(0005a1)InternalDrilldown - HPCStockAvail] AS Q
INNER JOIN [(0005a1)InternalDrilldown - HPCStockAvail] AS Q1
ON Q.du = Q1.du AND Q.casesLost <= Q1.casesLost
GROUP BY Q.du, Q.casesLost
HAVING COUNT(*) <= 5





You can even improve the speed further if you can make a temp table of your
query [(0005a1)InternalDrilldown - HPCStockAvail], and index fields du and
casesLost (you cannot add indexes to a query, that is why you need a temp
table).






You can even speed up furthermore the whole thing by using a temporary table
and an intermediate query, and some extra work:


have a table temp, empty, with 3 fields: an autonumber, au, the primary key,
plus the two fields du, and casesLost. Append the data to temp from your
query with:

INSERT INTO temp(du, casesLost)
SELECT du, casesLost FROM [(0005a1)InternalDrilldown - HPCStockAvail]
ORDER BY du, casesLost


The autonumber will automatically be filled.

then:

SELECT du, MIN(au) AS myMin
FROM temp
GROUP BY du

as saved query qmin,


return the autonumber value which starts each sequence, so

finally


SELECT a.du, a.casesLost, a.au-b.myMin + 1 AS rank
FROM temp AS a INNER JOIN qmin AS b
ON a.du = b.du AND a.au <= 5=b.myMin



should return the desired values.


Note that you have to repeat the sequence: empty table temp, append data,
run the last query

each time some data changed. Maybe better doing that with a VBA subroutine
rather than calling these steps, manually.
