  • If you provide test tables in the form of CREATE TABLE statements and sample data in the form of INSERT INTO statements I would be happy to provide some working code to help you solve the issue.

    Without that I can refer you to this article:

  • If it's really URGENT, then you better to present your issue in a way it could be quickly addressed. Please have a read tips from the link at the bottom of my signature.

    DDL, sample data insert script and clear example of output (which you have already) will be very helpful.

    Otherwise you need to wait for someone less lazy to do it for you. I can assure you that it will be definitely done, but it will take a bit longer than "URGENT" 🙂

  • IF object_id('tempdb..#testEnvironment') IS NOT NULL

    BEGIN

    DROP TABLE #testEnvironment;

    END;

    SELECT CAST(dtDate AS DATETIME) AS dtDate, sDocIdPrefix, CNT

    INTO #testEnvironment

    FROM (SELECT '2013-02-11', 653, 3683 UNION ALL

    SELECT '2013-02-11', 649, 1334 UNION ALL

    SELECT '2013-02-12', 647, 1422 UNION ALL

    SELECT '2013-02-12', 649, 6602 UNION ALL

    SELECT '2013-02-12', 653, 4781

    )a(dtDate,sDocIdPrefix,CNT);

    Sample data is: -

    dtDate sDocIdPrefix CNT

    ----------------------- ------------ -----------

    2013-02-11 00:00:00.000 653 3683

    2013-02-11 00:00:00.000 649 1334

    2013-02-12 00:00:00.000 647 1422

    2013-02-12 00:00:00.000 649 6602

    2013-02-12 00:00:00.000 653 4781

    Using the sample data above, then I think that this is what you're after: -

    DECLARE @sql NVARCHAR(MAX);

    SELECT @sql = 'SELECT dtDate,' + sqlCode + CHAR(13) + CHAR(10) + 'FROM #testEnvironment'+CHAR(13)+CHAR(10)+'GROUP BY dtDate;'

    FROM (SELECT STUFF((SELECT ',' + CHAR(13)+CHAR(10)+

    'MAX(CASE WHEN sDocIdPrefix = ' + CAST(sDocIdPrefix AS VARCHAR(20)) + ' THEN CNT ELSE 0 END) AS '+

    QUOTENAME(CAST(sDocIdPrefix AS VARCHAR(20)))

    FROM (SELECT DISTINCT sDocIdPrefix

    FROM #testEnvironment

    )a

    ORDER BY sDocIdPrefix DESC

    FOR XML PATH(''),TYPE

    ).value('.','VARCHAR(MAX)'),1,1,'')

    )dynSql(sqlCode)

    EXECUTE sp_executesql @sql;

    Produces: -

    dtDate 653 649 647

    ----------------------- ----------- ----------- -----------

    2013-02-11 00:00:00.000 3683 1334 0

    2013-02-12 00:00:00.000 4781 6602 1422

    Look at how I laid out the sample data, it makes it considerably easier for people to help when it looks like that
