不存在的T-SQL返回记录

Question

我对SQL很陌生，我需要一种方法来返回NULL或0，对于每个外科医生没有记录的年份和季度。只有2个产品系列应该返回（膝盖和肩部），如果外科医生曾经使用过该产品，我只需要缺少年份/季度。例如，如果史密斯，约翰只有膝盖，那么我不需要肩膀的零点。

这是我到目前为止的查询，但我一直未能弄清楚如何包括没有值的年份和季度。

SELECT q.Surgeon_Name , 
     q.Product_Family , 
     First_Date , 
     q.Year , 
     q.Quarter , 
     CAST(ROUND(q.Monthly_Average, 2) AS MONEY) AS 'Monthly Average' 
FROM (SELECT DISTINCT 
        RTRIM(confirmed_to) AS 'Surgeon_Name' , 
        Product_Family , 
        YEAR(rev_ship_date) AS 'Year' , 
        DATENAME(Quarter, CAST(REV_SHIP_DATE AS DATETIME)) AS 'Quarter' , 
        (SUM(amount)/3) AS 'Monthly_Average' 
      FROM  Vsoicl 
        LEFT JOIN Product_Line_Desc ON vsoicl.PART_ID = Product_Line_Desc.Part_ID 
      WHERE  vsoicl.PRODUCT_LINE <> 'MIRR' 
        AND Product_Family IS NOT NULL 
        AND Product_Family <> 'NULL' 
        AND CONFIRMED_TO <> '' 
        AND REV_SHIP_DATE >= '2013-01-01' 
      GROUP BY CONFIRMED_TO , 
        Product_Family , 
        YEAR(rev_ship_date) , 
        DATENAME(Quarter, CAST(REV_SHIP_DATE AS DATETIME)) 
     ) AS q 
     LEFT JOIN (SELECT DISTINCT 
          RTRIM(confirmed_to) AS 'Surgeon_Name' , 
          Product_Family , 
          CAST(MIN(rev_ship_date) AS DATE) AS 'First_Date' 
        FROM Vsoicl 
          LEFT JOIN Product_Line_Desc ON vsoicl.PART_ID = Product_Line_Desc.Part_ID 
        WHERE vsoicl.PRODUCT_LINE <> 'MIRR'

          AND Product_Family <> 'NULL' 
        GROUP BY CONFIRMED_TO , 
          Product_Family 
       ) AS f ON q.surgeon_name = f.Surgeon_Name 
          AND q.Product_Family = f.Product_Family 
ORDER BY Surgeon_Name , 
     Product_Family , 
     Year , 
     Quarter 

任何援助将不胜感激。

昨晚我想到了它。

我读过快快SQL和修订想到会是

所有年的利息/宿舍创建myCalendar表（myYYYY，MYQQ）。只有40行

然后用十字加入为“正片叠底”的外科医生/产品每个YYYYQQ

SELECT 
    just.Surgeon_Name , 
    just.Product_Family , 

    myYYYY , 
    myQQ , 

    First_Date , 
    [Monthly Average] 

FROM (
    (SELECT DISTINCT 
       RTRIM(confirmed_to) AS 'Surgeon_Name' , 
       Product_Family , 
     FROM  Vsoicl 
     WHERE  PRODUCT_LINE <> 'MIRR' 
      AND Product_Family IS NOT NULL 
      AND Product_Family <> 'NULL' 
      AND CONFIRMED_TO <> '' 
      AND REV_SHIP_DATE >= '2013-01-01' 
    ) as just 

, myCalendar 
     ) 

LEFT JOIN 
    (the above sql) as myV 
    ON just.Surgeon_Name = myV.Surgeon_Name 
    and just.Product_Family= myV.Product_Family 
    and myYYYY = Year 
    and myQQ = Quarter
