我在master..spt_values支持的 SQL Server 中使用它，将其用作“月”数字支持（不要问我为什么；可能是旧查询即时写入）：

SELECT 
    months.number as Month, 
    ISNULL(t2.NumVisits, 0) AS NumVisits, 
    ISNULL(t2.NumActivities, 0) AS NumActivities,
    ISNULL(t2.Estimated, 0) AS Estimated,
    ISNULL(t2.Accepted, 0) AS Accepted,
    ISNULL(t2.PercAccepted, 0) AS PercAccepted,
    ISNULL(t2.PercValue, 0) AS PercValue
FROM master..spt_values months
LEFT JOIN 
    (SELECT 
        *,
        CASE WHEN t1.NumVisits <> 0 THEN (CAST(t1.NumActivities AS DECIMAL) / t1.NumVisits) * 100 ELSE 0 END AS PercAccepted,
        CASE WHEN t1.Estimated <> 0 THEN (CAST(t1.Accepted AS DECIMAL) / t1.Estimated) * 100 ELSE 0 END AS PercValue
    FROM
        (SELECT
            MONTH(DateVisit) AS Month, 
            COUNT(*) AS NumVisits,
            SUM(CASE WHEN DateActivity is not null THEN 1 ELSE 0 END) AS NumActivities,
            SUM(Estimate) AS Estimated,
            SUM(CASE WHEN DateActivity is not null THEN Estimate ELSE 0 END) AS Accepted
        FROM [dbo].[Activities]
        WHERE 
            DateVisit IS NOT NULL 
            AND (@Year IS NULL OR YEAR(DateVisit) = @Year) 
            AND (@ClinicID IS NULL OR ClinicID = @ClinicID)
            AND (@MedicalID IS NULL OR MedicalID = @MedicalID)
            AND (@TreatmentTypeID IS NULL OR TreatmentTypeID = @TreatmentTypeID)
        GROUP BY MONTH(DateVisit)) t1
        ) t2
    ON months.number = t2.Month
WHERE 
    Type = 'P' AND number BETWEEN 1 AND 12
    AND (@QuarterID IS NULL 
        OR (@QuarterID = 1 AND months.number <= 3) 
        OR (@QuarterID = 2 AND months.number > 3 AND months.number <= 6) 
        OR (@QuarterID = 3 AND months.number > 6 AND months.number <= 9) 
        OR (@QuarterID = 4 AND months.number > 9 AND months.number <= 12))
ORDER BY months.number

不幸的是，现在我需要在另一个master..spt_values不支持的 SQL Server (Azure) 上迁移数据库：

Reference to database and/or server name in 'master..spt_values' is not supported in this version of SQL Server.

如何在上面的查询中快速替换该表？本地表？有什么例子吗？
