sql server programming:

i want to a query.

SELECT MAX(fNum) FROM tTable WHERE fDate IN (SELECT MAX(fDate) FROM
tTable WHERE fDate IN (SELECT fDate
FROM tTable WHERE fDate IN (SELECT fDate FROM tTable WHERE
(fRegion="Califo") AND (fProduct="G274") AND (fColor="Brown") AND
(fDate<=#5/13/2006#))))

unfortunately, the upper query is not working in my hope.
i want to following query.

there are records in (fRegion="Califo") AND (fProduct="G274") AND
(fColor="Brown") AND (fDate<=#5/13/2006#).
there are records in maximum fDate in the records.
and then last
there is record of a maximum fNum in the records.

Hi,
Can you give the ddl and insert scripts for sample data and the result you
expect for the given sample data? That way we can understand the problem

As Omnibuzz said, more information is needed.

While your query seems to be written for Access, since this is a SQL
Server group I took the liberty of changing it to SQL Server syntax. I
rewrote the query to eliminate some of the levels, but it should
return the same results as the example:

SELECT MAX(fNum)
FROM tTable
WHERE fDate =
(SELECT MAX(fDate)
FROM tTable
WHERE fRegion = 'Califo'
AND fProduct = '1G274'
AND fColor = 'Brown'
AND fDate <= '13 May 2006')

It doesn't do anything new, but it is perhaps another way to
understand what the original is doing.
