访问SQL查询:不在相关表的间隔之间返回值



我有2个表(间隔和深度)与名称字段相关。我希望查询能够返回每个名称间隔表中不在间隔表中的所有深度(或不等于顶部和底部之间)。当间隔表中有多个名称记录时,我的查询失败(示例:名称字段中有2个"一个"记录)。

间隔

Name    Top    Bottom
one     2      3
one     5      7
two     2      3
three   3      4

深度

Name    Depth
one     1
one     2
one     3
one     4
one     5
one     6
one     7
one     8
two     1
two     2
two     3
two     4
two     5
three   1
three   2
three   3
three   4
three   5

我的查询:

SELECT Intervals.Name, Depths.Depth
FROM Depths INNER JOIN Intervals ON Depths.Name = Intervals.Name
WHERE (((Depths.Depth) < [Intervals]![Top] 
    Or (Depths.Depth) > [Intervals]![Bottom]))
ORDER BY Intervals.Name, Depths.Depth;

我知道这失败了,因为将Where子句单独应用于每个名称记录的时间间隔。WHERE子句应适用于按名称相关的所有间隔记录,因此结果不包含间隔表中的任何自上而下的间隔。

我的查询输出:

Name    Depth
one     1
one     1   
one     2    
one     3
one     4    
one     4
one     5
one     6
one     7
one     8   
one     8
three   1
three   2
three   5
two     1
two     4
two     5

所需的输出:所有深度不在间隔

Name    Depth   
one     1       
one     4       
one     8       
two     1
two     4
two     5
three   1
three   2
three   5

您的问题的措辞建议not exists,因此这可能对您有用:

select d.*
from depths as d
where not exists (select 1
                  from intervals as i
                  where i.name = d.name and d.depth between i.[top] and i.[bottom]
                 );
