LEFT OUTER JOIN MATCHING

Question

我有以下查询，我修改它以便能够查看名为Futuredial_Validation的新表，我写了所有的条件和连接但是它仍然没有查看表，只是在一个名为cellscripter的表中，查询的其余部分有效，我非常感谢任何帮助，谢谢：

SELECT row_number() OVER (ORDER BY wms_us.wms_us.rrno.rrdate, wms_us.wms_us.rrno.pono, wms_us.wms_us.transferboxdet.meidhex, att.Date_cleared) AS ROW_ID,
  wms_us.wms_us.rrno.pono                                                                                                                      AS ATT_PO,
  wms_us.wms_us.rrno.rrdate                                                                                                                    AS Received_Date,
  CASE
    WHEN (wms_us.wms_us.model.modeldesc = 'MIXED')
    THEN wms_us.wms_us.transferboxdet.basemodel
    ELSE wms_us.wms_us.model.modelbase
  END AS Model,
  CASE
    WHEN LEN(wms_us.wms_us.transferboxdet.meidhex) >= 15
    THEN LEFT(wms_us.wms_us.transferboxdet.meidhex, 14)
    ELSE wms_us.wms_us.transferboxdet.meidhex
  END AS IMEI,
  /*Check in Futerdial else obtain the values from cellscripter*/
  CASE
    WHEN (Future.[Error Code] = '1')
    THEN Future.LocalTime
    ELSE att.Date_cleared
  END AS Date_cleared,
  CASE
    WHEN (Future.[Error Code] = '1')
    THEN 'PASS'
    ELSE att.Result
  END AS Result

WHERE (wms_us.wms_us.rrno.rrdate > '2016-12-01')

最有可能的情况是：您的加入规范无效或case的{​​{1}}表达式不正确。

检查您是否获得[Error Code]和[Future_imei]的任何值：

[Error Code]
