我需要第三列重订为100，所以我写了下面这工作完美：

WITH CTE 
AS (
    SELECT CASE 
      WHEN shareClassdata.valueDate IS NULL 
       THEN NULL 
      ELSE performanceData.valueDate 
      END AS valueDate 
     ,CASE 
      WHEN shareClassdata.benchmarkTypeName IS NULL 
       THEN NULL 
      ELSE performanceData.benchmarkTypeName 
      END AS benchmarkTypeName 
     ,CASE 
      WHEN shareClassdata.NAVLocal IS NULL 
       THEN NULL 
      ELSE performanceData.NAVLocal 
      END AS NAVLocal 
    FROM getPerformances(2, 12045, 0, 308, 31) AS performanceData 
    LEFT JOIN (
     SELECT * 
     FROM getPerformances(2, 12045, 0, 308, 31) 
     ) shareClassdata ON shareClassdata.shareClassGroupId = performanceData.shareClassGroupId 
     AND shareClassdata.currencyId = performanceData.currencyId 
     AND shareClassdata.financialStructureGroupId = performanceData.financialStructureGroupId 
     AND shareClassdata.valueDate = performanceData.valueDate 
     AND shareClassdata.benchmarkTypeName = 'Fund' 
    WHERE performanceData.shareClassGroupId = 22050 
     AND performanceData.valueDate <= '2017-06-30 00:00:00.000' 
     AND (
      isnull(performanceData.valueDate, '') <> '' 
      AND (
       performanceData.benchmarkTypeName = 'Benchmark' 
       OR performanceData.benchmarkTypeName = 'Fund' 
       ) 
      ) 
    ) 
SELECT valueDate 
    ,benchmarkTypeName 
    ,(
     sum(a.NAVLocal)/(
      SELECT TOP 1 b.NAVLocal 
      FROM CTE AS b 
      WHERE b.NAVLocal != 0 
       AND a.benchmarkTypeName = b.benchmarkTypeName 
      ORDER BY b.valueDate ASC 
      ) 
     ) * 100 AS NAVLocal 
FROM CTE AS a 
WHERE valueDate IS NOT NULL 
    AND benchmarkTypeName IS NOT NULL 
GROUP BY valueDate 
    ,benchmarkTypeName 
ORDER BY benchmarkTypeName ASC 
    ,valueDate ASC

它给出了以下结果（注意：列NAVLocal只是在那里向你展示旧vs前值）：

但是查询的运行速度非常非常大型数据集很慢。有没有更好的方法来执行这个计算？

关于基础重建数A提醒：
对于每一个系列的标杆，其结果将按升序排序的价值date.The最重要的价值是每个系列的最早的记录。该系列中的每一个NAV值由最古老的NAV分，由100

乘以您可以用公式访问此电子表格 https://docs.google.com/spreadsheets/d/1esChCFPTLa9df3xWuLmT5-JONsS8j8vTZpAjsx7fb9M/edit?usp=sharing

请告诉我们预期的结果，并添加一个标签与您所使用的SQL Server版本。预期的结果将解释“将第三列重新设置为100”的含义。 –

窗口功能可以帮助提高性能，我从第一输出开始，但你应该得到它如何可以与一个窗函数来实现这个想法
