我有一个查询，我得到这样的结果，我得到下面的结果集。但我需要得到如上一个所示

SELECT DISTINCT                     LEFT(DATENAME(m, CONVERT(DATE, CONVERT(VARCHAR(10), fcp.DateKey))), 3) + ' ' + CONVERT(VARCHAR(4), year(convert(DATE, CONVERT(VARCHAR(10), fcp.DateKey)))) DatePeriod
        ,OM.HedisOCMKey AS OutComeMeasureKey
        ,(
            SELECT NumeratorSegmentCnt
            FROM Fact.HedisOCMSegments omse
            WHERE omse.SegmentLabel = 'Good'
                AND omse.HedisOCMKey = OM.HedisOCMKey
            ) AS Good
        ,0 AS Fair
        ,0 AS Poor
        ,0 AS 'NotCategorised'
                FROM fact.HEDISReport fcp WITH (NOLOCK)
    INNER JOIN fact.HedisOCM OM WITH (NOLOCK)
        ON OM.HEDISReportKey = fcp.HEDISReportKey
    INNER JOIN dim.ConditionMetric dc WITH (NOLOCK)
        ON dc.ConditionMetricID = OM.MetricID
    WHERE fcp.DateKey <= @i_ReportingPeriod

我的输出是这样的：

ConditionPrevalenceKey  PopulationConditionCnt  PrevalencePercent   DatePeriod  OutComeMeasureKey   Good    Fair    Poor    NotCategorised  NotTested   GoodPercentage  FairPercentage  PoorPercentage  NotCategorisedPercentage    NotTestedPercentage GoodRange   FairRange   PoorRange   NotCategorisedRange NotTestedRange  DerivedGoodValue    DerivedFairValue    DerivedPoorValue    DerivedNotCategorised   DerivedNotTested    ConditionMetricName


18018   252 0.53    Dec-12  34957   35  0   0   0   217 13.89   0   0   0   86.11   Good    Fair    Poor    NC  NoData  >= 1    0   0   NotCategorized  NotTested   Chlamydia  Screen

那么我怎样才能得到这样的结果集：

year    Legend  percent count   Derived value field


Dec-12  Good    13.89   35  >= 1

Dec-12  Fair    0   0   0

Dec-12  Poor    0   0   0

Dec-12  NC  0   0   0

建议我？？？

我会使用 UNPIVOT。在 stackoverflow 上有很多关于 UNPIVOT 的线程。这是一个例子。这是另一个非常相似的。

这是使用 UNPIVOT 解决您的特定问题的一般开始：

SELECT  [DatePeriod] ,
        [OutComeMeasureKey] ,
        [Legend] ,
        [Percent]
FROM    (SELECT DISTINCT
                LEFT(DATENAME(m, CONVERT(DATE, CONVERT(VARCHAR(10), fcp.DateKey))), 3) + ' ' + CONVERT(VARCHAR(4), YEAR(CONVERT(DATE, CONVERT(VARCHAR(10), fcp.DateKey)))) DatePeriod ,
                OM.HedisOCMKey AS OutComeMeasureKey ,
                (SELECT NumeratorSegmentCnt
                 FROM   Fact.HedisOCMSegments omse
                 WHERE  omse.SegmentLabel = 'Good' AND omse.HedisOCMKey = OM.HedisOCMKey
                ) AS Good ,
                0 AS Fair ,
                0 AS Poor ,
                0 AS 'NotCategorised'
         FROM   fact.HEDISReport fcp WITH (NOLOCK)
                INNER JOIN fact.HedisOCM OM WITH (NOLOCK) ON OM.HEDISReportKey = fcp.HEDISReportKey
                INNER JOIN dim.ConditionMetric dc WITH (NOLOCK) ON dc.ConditionMetricID = OM.MetricID
         WHERE  fcp.DateKey <= @i_ReportingPeriod
        ) AS sourcetable UNPIVOT ( [Percent] FOR Legend IN (Good, Fair, Poor, [NotCategorised]) ) AS unpvt
