我有两个与名称字段相关的表格(间隔和深度)。我希望查询返回每个名称不在Intervals表中的所有深度(或者不等于Top或Bottom之间或之间)。在“间隔”表中有多个“名称”记录时,我的查询失败(例如:“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
深渊
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;
我知道这会失败,因为Where子句是单独应用于Interval中的每个Name记录的。 Where子句应该适用于与Name相关的所有Interval记录,因此结果不包括Interval表中的Top to Bottom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
所需输出:所有深度不以间隔
Name Depth
one 1
one 4
one 8
two 1
two 4
two 5
three 1
three 2
three 5
答案 0 :(得分:2)
您的问题的措辞提示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]
);
