我需要帮助过滤下面的查询结果。具体来说，我只需要返回dbo.pertot_all.sort_method = 2where 子句中指定的所有日期的结果 where 。目前，使用下面提供的内容，它正在返回其他 sort_methods。我不熟悉 AND/OR 运算符的顺序/分组。有人可以提供一些指导吗？提前致谢。

 SELECT     dbo.SiteDescription.Site, dbo.SiteDescription.Description AS SiteDescription, dbo.SiteDescription.LocationGroup, dbo.chart_all.acct, dbo.pertot_all.sf2, 
                  dbo.SSRS_sf2UnitCodes.sf2description, dbo.pertot_all.sf4, dbo.SSRS_sf4UnitCodes.sf4description, dbo.chart_all.description AS AccountDescription,

这应该有效。

您可以使用语句大大简化查询in。考虑以下：

select 1 where cast('1/1/2000' as datetime) in ('1/1/2000', '1/2/2000')

datetime如果在列表中，查询将返回一行。

您的查询可以重写为如下内容：

SELECT     fields
  FROM     tables
 WHERE     (ISNULL(dbo.pertot_all.sort_method, 2) = 2) AND
           (ISNULL(dbo.pertot_all.per_start, '2012-01-01 00:00:00.000') in ('2012-01-01 00:00:00.000', '2012-02-01 00:00:00.000', '2012-03-01 00:00:00.000', etc.))

您必须ISNULL()至少使用一次日期，因此您不会遇到 NULL 问题。但是您可以使用该in语句比较所有日期。
