Question

我对SQL非常陌生，我需要一种方法来返回 NULL 或0，对于每个外科医生来说，没有记录存在的年和季度。只有2个产品系列应该返回（膝盖和肩膀），如果外科医生曾经使用该系列产品，我只需要缺少年份/季度。例如，如果史密斯，约翰只有膝盖，那么我不需要为肩膀做空。

这是我到目前为止的查询，但我还没有弄清楚如何包含没有价值的年份和季度。

非常感谢任何帮助。

我昨晚才知道。

我在haste中读过sql，修改过的想法是

为所有感兴趣的年/季度创建myCalendar表（myYYYY，myQQ）。这将是一个小桌子，10年只有40行

然后使用交叉连接来＆＃34;乘以＆＃34;每个YYYYQQ的外科医生/产品

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

T-SQL返回不存在的记录
