【问题描述】：

我正在尝试编写一个 SQL 查询，其中将提取包含所有项目及其尺寸的数据，并且必须满足以下条件：长度 >=20 或宽度 >=14 或高度 >=10（所有项目不适合 20x14x10 的容器）。问题是高度可能大于长度（想象在空间中翻转项目）。我写了一个代码，但我认为它不会涵盖所有情况。下面是我试过的代码：

select 
items.bin_id,
items.bin_type_name,    
items.bin_usage_name,    
items.isbn,
items.boo,
items.quantity,
ma.pkg_height,
ma.pkg_width,  
ma.pkg_length,    
ma.pkg_weight,
items.owner
from items 
left join BOOKER.D_MP_PHYSICAL_ITEMS ma
on items.boo = ma.asin

where ((ma.pkg_length >= 20 AND ma.pkg_width >= 14 AND ma.pkg_height >= 10) OR 
    (ma.pkg_length >= 14 AND ma.pkg_width >= 10 AND ma.pkg_height >= 20) OR 
    (ma.pkg_length >= 10 AND ma.pkg_width >= 20 AND ma.pkg_height >= 14) OR

    ((ma.pkg_length >= 20 AND ma.pkg_width >= 10 AND ma.pkg_height >= 14) OR 
    (ma.pkg_length >= 14 AND ma.pkg_width >= 20 AND ma.pkg_height >= 10) OR     
    (ma.pkg_length >= 10 AND ma.pkg_width >= 14 AND ma.pkg_height >= 20))
     

我的另一个想法是从项目的尺寸中选择最大值并检查它是否大于 20，然后选择最小值并查看它是否大于 10 并检查最后一个数字是否大于 14（以防万一其中两个第一个值给出 FALSE），但我不能把它放在 SQL 中

【参考方案1】：

我想下面的逻辑会起作用（基本上我已经尝试为您在问题的后面部分中提到的逻辑编写查询）：

with temp_cte as (
    select 
    items.*, ma.*,
    Select dim from
      (SELECT dim, row_number() over (order by dim desc) as rn
       FROM (VALUES (ma.pkg_length), (ma.pkg_height), (ma.pkg_width)) AS value(dim)) where rn = 1) as length,
    Select dim from
      (SELECT dim, row_number() over (order by dim desc) as rn
       FROM (VALUES (ma.pkg_length), (ma.pkg_height), (ma.pkg_width)) AS value(dim)) where rn = 2) as height,
    Select dim from
      (SELECT dim, row_number() over (order by dim desc) as rn
       FROM (VALUES (ma.pkg_length), (ma.pkg_height), (ma.pkg_width)) AS value(dim)) where rn = 3) as width
    from items 
    left join BOOKER.D_MP_PHYSICAL_ITEMS ma
    on items.boo = ma.asin
    where 
        length >= 20 or height >= 14 or width >= 10
)

Select 
    bin_id,
    bin_type_name,    
    bin_usage_name,    
    isbn,
    boo,
    quantity,
    pkg_height,
    pkg_width,  
    pkg_length,    
    pkg_weight,
    owner
from temp_cte;
