我需要协助过滤以下查询的结果。具体来说，我只需要返回where dbo.pertot_all.sort_method = 2中where子句中指定的所有日期的结果。目前，使用下面提供的内容，它将返回其他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？非常感谢提前。

这应该有用。
答案 1 :(得分：0)
您可以使用in语句大大简化查询。请考虑以下事项：
select 1 where cast('1/1/2000' as datetime) in ('1/1/2000', '1/2/2000')
如果datetime在列表中，查询将返回一行。
您的查询可以重写为以下内容：
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.))
您必须至少使用ISNULL()一次日期，因此您不会遇到NULL问题。但您可以使用in语句比较所有日期。
