我有三个DM_EVENT.event_code：

'DRL'
'CMP'
'WOV'

我需要使用日期参数来选择所需的最新报告日期（在此示例'4/28/15'中：）以提取该SUM(DM_DAILYCOST.cost_per_item)日期的截止日期。'CMP'并且'WOV'可以使用所选日期。

但是，对于 code 'DRL'，我需要拉SUM(DM_DAILYCOST.cost_per_item)for DATEADD(d,-1,'4/28/15')。

我想我让它变得比它需要的更难，但我被困在一个解决方案上。非常感谢任何见解！

SELECT cd_well.completion_well_id,

       Sum(dm_dailycost.cost_per_item) AS Expr1,

WHERE您所需要的只是陈述中的正确条件。您应该只选择'CMP'and 'WOV'events at date'4/28/15'和'DRL'events at date DATEADD(d,-1,'4/28/15')：

SELECT
 ...,
 SUM(dm_dailycost.cost_per_item) as Expr1,
 ...
FROM ...
INNER JOIN ...
...
WHERE
      dm_event.event_code in ('CMP', 'WOV') 
  AND dm_report_journal.date_report = '4/28/15'
  OR 
      dm_event.event_code = 'DRL'
  AND dm_report_journal.date_report = DATEADD(d,-1,'4/28/15')
GROUP BY ...

并从查询中删除您的 HAVING 语句。
