Row with Non-Zero Value

    #357304

    I have the following table and want to find the row with non-zero value for revenue and quantity for each combination.
    So the result should be three rows as below: Thanks.
    3 a
    2 b
    1 c

    create table #temp
    (
        prodID int
        ,mktID nvarchar(255)
        ,rev decimal
        ,qty decimal
    )

    insert into #temp (prodID, mktID, rev, qty)
    values (1, 'a', 100, 10)
    insert into #temp (prodID, mktID, rev, qty)
    values (2, 'a', 102, 11)
    insert into #temp (prodID, mktID, rev, qty)
    values (3, 'a', 110, 12)
    insert into #temp (prodID, mktID, rev, qty)
    values (1, 'b', 200, 10)
    insert into #temp (prodID, mktID, rev, qty)
    values (2, 'b', 202, 11)
    insert into #temp (prodID, mktID, rev, qty)
    values (3, 'b', 0, 0)
    insert into #temp (prodID, mktID, rev, qty)
    values (1, 'c', 310, 12)
    insert into #temp (prodID, mktID, rev, qty)
    values (2, 'c', 0, 0)
    insert into #temp (prodID, mktID, rev, qty)
    values (3, 'c', 0, 0)

    select * from #temp

    Why would the first result be (3 a), when (1 a) and (2 a) also appear to have non-zero values for revenue and quantity?

    Just seems to me to be a simple group by:
    CREATE TABLE #temp (
        prodID int,
        mktID nvarchar(255),
        rev decimal,
        qty decimal,
        UNIQUE CLUSTERED
            (
            mktID ASC,
            prodID ASC
            )
    );
    INSERT INTO #temp (prodID, mktID, rev, qty)
        VALUES    (1, 'a', 100, 10),
                (2, 'a', 102, 11),
                (3, 'a', 110, 12),
                (1, 'b', 200, 10),
                (2, 'b', 202, 11),
                (3, 'b', 0, 0),
                (1, 'c', 310, 12),
                (2, 'c', 0, 0),
                (3, 'c', 0, 0);

    SELECT
        COUNT(T.prodID) AS [count],
        T.mktID
    FROM #temp AS T
    WHERE    T.qty <> 0
        AND T.rev <> 0
    GROUP BY T.mktID
    ORDER BY COUNT(T.prodID) DESC;

    DROP TABLE #temp;

    I chose to add an appropriate clustered index based solely on this query, so take that for what it's worth.   Just didn't see a need to add a row number when GROUP BY works just fine.

    Maybe I'm reading the OP's (clarified) requirements wrong.

    But I don't think he wants a count of the number of non-zero values.  Rather, he wants the highest prod id with non-zero values.

    So maybe MAX instead of COUNT?

    select MAX(ProdId) ProdId, mktId
    from #temp
    where rev <> 0
    and qty <>0
    group by mktId
    order by 1 desc

    The OP specified the desired results up front.

    Yes, they said: "Highest prod I’d" not count

    Ahhhh, yes...   I do see that post now....  Interesting that the data just happens to also coincide with the COUNT values for the number of prodID's that have non-zero revenue and quantity values.   Not sure the OP is still looking at this thread, so I'll propose a question:  What would the results be if the data included an additional mktID value?
    CREATE TABLE #temp (
      prodID int,
      mktID nvarchar(255),
      rev decimal,
      qty decimal,
      UNIQUE CLUSTERED
       (
       mktID ASC,
       prodID ASC
       )
    );
    INSERT INTO #temp (prodID, mktID, rev, qty)
      VALUES (1, 'a', 100, 10),
        (2, 'a', 102, 11),
        (3, 'a', 110, 12),

        (2, 'c', 0, 0),
        (3, 'c', 0, 0),
                (1, 'd', 0, 0),
        (2, 'd', 202, 21),
        (3, 'd', 210, 22);
        
    SELECT
      COUNT(T.prodID) AS [count],    --prodID,
      T.mktID
    FROM #temp AS T
    WHERE T.qty <> 0
      AND T.rev <> 0
    GROUP BY T.mktID
    ORDER BY COUNT(T.prodID) DESC;

    SELECT
      MAX(T.prodID) AS prodID,
      T.mktID
    FROM #temp AS T
    WHERE T.qty <> 0
      AND T.rev <> 0
    GROUP BY T.mktID
    ORDER BY MAX(T.prodID) DESC;

    DROP TABLE #temp;
    /*

     3  a
     3  d
     2  b
     1  c
    */

    Had to play with the data a bit to make a scenario that differed between the two methods.   Now if we could just interest the original poster in this question...
