其中日期时间不在 Select 之间

Question

我想知道如何 select 我的日期时间不在 select 之间的一些行。

我当前的 Select 看起来像这样：

SELECT LOG.*
FROM LOG
WHERE   LOG.[date]      >=  @startDate
AND     (LOG.[date]     <=  @endDate OR @endDate IS NULL)
AND     LOG.[date] NOT IN BETWEEN ANY PAIR FROM (SELECT ADMINaction.Start,ADMINaction.Ende 
                               FROM ADMINaction 
                               WHERE     ADMINaction.Start      >=  @startDate
                               AND      (ADMINaction.Ende   <=  @endDate OR @endDate IS NULL))

但这不是一个有效的查询。

我需要如何修改它才能使其有效？

A: NO, the sub-query can contain any number of results

如果您 100% 确定用于确定开始日期和结束日期的查询仅 returns 一条记录，则可以执行此操作（可以肯定的是，您可以包含 TOP 1在内部 SELECT):

SELECT *
FROM LOG CROSS JOIN
    (SELECT Start,Ende 
     FROM ADMINaction 
     WHERE     [date]     >=  @startDate
     AND      ([date]     <=  @endDate OR @endDate IS NULL)
) DateFilter
WHERE   LOG.[date]      >=  @startDate
AND     (LOG.[date]     <=  @endDate OR @endDate IS NULL)
AND     LOG.[date] NOT BETWEEN DateFilter.Start AND DateFilter.Ende

如果您的 ADMINaction table 仅包含 1 条记录，您可以将此查询简化为：

SELECT *
FROM LOG CROSS JOIN ADMINaction
WHERE   [date]      >=  @startDate
AND     ([date]     <=  @endDate OR @endDate IS NULL)
AND     [date] NOT BETWEEN Start AND Ende

Answer 2

据推测，您想要 left join 或 not exists:

SELECT l.*
FROM LOG l
WHERE l.[date] >=  @startDate AND
      (l.[date] <=  @endDate OR @endDate IS NULL) AND
      NOT EXISTS (SELECT 1
                  FROM ADMINaction a
                  WHERE l.[date] >= a.Start AND
                        (l.[date] <= a.Ende OR a.Ende IS NULL)
                 );

这 returns 来自 log 的行，其中日志日期在 ADMINaction 中没有相应的时间间隔。这似乎是你查询的意图。
