Powershell 仅在第 2 列 -cge 第 3 列基于第 1 列的组中显示行
[英]Powershell Display rows only if column 2 -cge column 3 for a group based on column 1
问题描述
我有一个这样的 csv：
MPN,Per_Pallet,Customer_Order,Customer_Order_Date,Backordered_by_Pallet,Reserved_Sum
501,116.82,12055,4/28/2021,3.18,1.02
501,116.82,12421,6/7/2021,2.36,1.02
501,116.82,12424,6/7/2021,3.91,1.02
2243,30,12014,4/26/2021,1.4,1
2243,30,12425,6/7/2021,4.8,1
2243,30,12817,7/21/2021,0.4,1
2243,30,13359,9/29/2021,0.6,1
2435,50.22,12014,4/26/2021,1,2
2435,50.22,13311,9/24/2021,1.14,2
218,40,13236,9/15/2021,3,5
218,40,13382,10/4/2021,3,5
7593,64,12670,7/2/2021,5,5
484,8,12582,6/22/2021,0.38,2
484,8,12798,7/16/2021,1.38,2
484,8,13255,9/18/2021,1,2
484,8,13288,9/22/2021,1,2
5647,87,13304,9/23/2021,0.01,1
我需要按 MPN 列分组，然后首先检查最早的订单，看看 Backordered_by_Pallet 是否大于或等于 Reserved_Sum。
如果是 -cge 则只显示该组的那一行。 如果不是，则检查下一个订单和第一个订单是否是并显示它们等等。 直到支持的总数大于 Reserved_Sum
这就是我脑海中的样子：
look at oldest order first for matching MPN
if oldest orders Backordered > Reserved Sum
Then only display oldest order
Else if oldest order + second oldest order > Reserved Sum
then display both orders
Else If Less Than, Add Next Order etc
预期输出：
MPN,Per_Pallet,Customer_Order,Customer_Order_Date,Backordered_by_Pallet,Reserved_Sum
501,116.82,12055,4/28/2021,3.18,1.02
2243,30,12014,4/26/2021,1.4,1
2435,50.22,13311,9/24/2021,1.14,2
218,40,13236,9/15/2021,3,5
218,40,13382,10/4/2021,3,5
7593,64,12670,7/2/2021,5,5
484,8,12582,6/22/2021,0.38,2
484,8,12798,7/16/2021,1.38,2
484,8,13255,9/18/2021,1,2
5647,87,13304,9/23/2021,0.01,1
我已经得到了不同的作品，但我无法弄清楚如何将它们组合在一起：
如果它更大或不是很容易返回：
$Magic | ForEach-Object {
If ($_.Backordered_by_Pallet -cge $_.Reserved_Sum) {$_}
Else {"Nothing To Order"}
}
我已经尝试通过以下方式添加到一个组中
$Magic | Group-Object MPN | ForEach-Object {
If ($_.group.Backordered_by_Pallet -cge $_.group.Reserved_Sum) {$_}
Else {"Nothing_Left_To_Order"}
}
但这会显示整个组或什么都不显示，我不知道如何将它们全部组合起来，更不用说如何在需要时添加前一行的数量了。
我相信我需要为每个都做几层深，所以我对 MPN 进行分组，为那个 mpn 创建一个数组，然后为该数组上的每个创建一个数组（按最旧排序）（不知道如何将前一行拉到add) 然后只导出结果，然后循环移动到下一组，依此类推。
像这样？ 我知道这不是真的，我就是想不通
$Magic_Hash = $Magic_File | Group-Object -Property MPN -AsHashTable | Sort $_.group.Customer_Order_Date
ForEach ($item in $Magic_Hash) {
If ($item.group.Backordered_by_Pallet -cge $_.group.Reserved_Sum) {$_}
Elseif ($item.group.Backordered_by_Pallet + $item.group.Backordered_by_Pallett["2nd oldest order"] -cge $_.group.Reserved_Sum) {$_}
else {"Nothing_Left"}
}
```
Thank you so much for all your help this community is amazing

第一步是根据MPN列/属性对记录进行分组，因此让我们先使用适当命名的Group-Object cmdlet 进行Group-Object ：
$records = @'
MPN,Per_Pallet,Customer_Order,Customer_Order_Date,Backordered_by_Pallet,Reserved_Sum
501,116.82,12055,4/28/2021,3.18,1.02
501,116.82,12421,6/7/2021,2.36,1.02
501,116.82,12424,6/7/2021,3.91,1.02
2243,30,12014,4/26/2021,1.4,1
2243,30,12425,6/7/2021,4.8,1
2243,30,12817,7/21/2021,0.4,1
2243,30,13359,9/29/2021,0.6,1
2435,50.22,12014,4/26/2021,1,2
2435,50.22,13311,9/24/2021,1.14,2
218,40,13236,9/15/2021,3,5
218,40,13382,10/4/2021,3,5
7593,64,12670,7/2/2021,5,5
484,8,12582,6/22/2021,0.38,2
484,8,12798,7/16/2021,1.38,2
484,8,13255,9/18/2021,1,2
484,8,13288,9/22/2021,1,2
5647,87,13304,9/23/2021,0.01,1
'@ |ConvertFrom-Csv
$groups = $records |Group-Object MPN
既然它们都正确分组在一起，我们可以开始遍历每个组，按日期/订单号对关联的记录进行排序，然后输出第一个符合条件的记录：
foreach($group in $groups){
# sort records by order number
$recordsInGroup = $group.Group |Sort-Object Customer_Order
# filter records based on the criteria, output only the first 1
$recordsInGroup |Where-Object { +$_.Backordered_by_Pallet -ge $_.Reserved_Sum } |Select-Object -First 1
}
Where-Object过滤器中$_.Backordered_by_Pallet前面的+将使 PowerShell 将该值转换为[double] ，确保与$_.Reserved_Sum进行正确的数字比较

代码本身非常糟糕，但我相信这是有效的。 我添加了评论以或多或少地了解思考过程。
需要注意的一件事是， "Nothing To Order"没有位置或未定义您希望如何显示它，因为它是一个string ，如果您需要显示此信息，则可能必须将其插入其中一个单元格或为此创建一个新列。
