sql - 我有数千行的 NULL 结果。当它们不存在时，如何将它们排除在填充之外？

Question

我有一个代码可以查看我的销售员工。他最近受聘为已灭绝的客户创造增长。因此，在我们在 dbase 中拥有的 1,000 多个客户中，他只会影响 100 个。因此，在他的值所在的位置生成了很多行NULL。我希望报告排除这些客户行，以便更有效地了解我的管理层。我将如何做到这一点？

    select  T1.CardCode 'BP Code',
        T1.CardName 'BP Name',
        COUNT(CASE WHEN T1.SlpCode<>'37' THEN T0.DocNum END) '# of Orders',
        SUM(CASE WHEN T1.SlpCode<>'37' THEN T0.DocTotal END) 'Total Orders Amt',
        SUM(CASE WHEN T1.SlpCode<>'37' THEN T0.DOCTOTAL END)/
        COUNT(CASE WHEN T1.SlpCode<>'37' THEN T0.DocNum END) 'Avg Order Size',
        COUNT(CASE WHEN T1.SlpCode='37' THEN T0.DocNum END) '# of Orders',
        SUM(CASE WHEN T1.SlpCode='37' THEN T0.DocTotal END) 'Total Orders Amt',
        SUM(CASE WHEN T1.SlpCode='37' THEN T0.DOCTOTAL END)/
        COUNT(CASE WHEN T1.SlpCode='37' THEN T0.DocNum END) 'Avg Order Size'

from    ORDR T0 INNER JOIN OCRD T1 ON T0.CardCode=T1.CardCode

where   T0.DocStatus = 'C'
        AND T0.CANCELED <> 'Y'
        AND T0.DocDate >= '2015-05-26'

GROUP BY    T1.CardCode,
            T1.CardName

Order By    t1.CardName

Answer 1

尝试包括

AND T1.SlpCode is NOT NULL

Answer 2

select tnot.*, tyes.*

              OCRD.CardName 'BP Name',
              COUNT(ORDR.DocNum) '# of Orders',
              SUM(ORDR.DocTotal) 'Total Orders Amt'
         FROM OCRD
         LEFT JOIN ORDR

     ) tnot

              OCRD.CardName 'BP Name',
              COUNT(ORDR.DocNum) '# of Orders',

         FROM OCRD
         JOIN ORDR

     ) tyes
