尝试使用 join 聚合数据并得到奇数输出

Question

运行此查询时出现我尚未遇到的奇怪错误，此查询在 Netezza 中执行

      SELECT    a.CALENDAR_DATE,
  b.NewBusinessUnit,
  b.ResellerID,
  b.ResellerName,
  a.PRODUCT,
  a.CLI
  FROM  
  dbo.ADMIN.ODS_DICECNT_TTB_OUTPUT_ONE a
  left inner join ODS_LAYER.ADMIN.ODS_OSS_BFD_BFDAGENT AS C  A.agentid = C.AGENTID
  left inner join ODS_LAYER.ADMIN.ODS_DISECNT_NETWORK_CLI_TEST  b on C.AGENTID = b.ResellerID 
  WHERE NewBusinessUnit <> 'Inter-Co'
  AND b.NewBusinessUnit = 'Business Wholesale'

产生以下错误

Answer 1

没有什么叫做

left inner join

你应该把它改成

left join

而

left join

是一个

outer join

.

所以你甚至可以改成left outer join

SELECT a.CALENDAR_DATE, 
       b.NewBusinessUnit, 
       b.ResellerID, 
       b.ResellerName, 
       a.PRODUCT, 
       a.CLI 
FROM   dbo.ADMIN.ODS_DICECNT_TTB_OUTPUT_ONE a 
       LEFT JOIN ODS_LAYER.ADMIN.ODS_OSS_BFD_BFDAGENT AS C 
              ON A.agentid = C.AGENTID 
       LEFT JOIN ODS_LAYER.ADMIN.ODS_DISECNT_NETWORK_CLI_TEST b 
              ON C.AGENTID = b.ResellerID 
WHERE  NewBusinessUnit <> 'Inter-Co' 
       AND b.NewBusinessUnit = 'Business Wholesale';
