在PowerShell中进行内部联接(不使用SQL) [英] Inner Join in PowerShell (without SQL)
问题描述
我们如何在PowerShell或PowerCLI中使Inner-Join或Cross-Join成为东西?
即使我不是PowerCLI/PowerShell的新手，我对它们也有一个基本的了解，但实际上花了2天的时间来弄清楚这一点，无数篇文档和博客都没有用.
我真正想知道的是输入命令后是否
Get-Content File.txt
并获得:
Output1 or Table1 is Name: Abc Group: Bad Policy: Great Name: redi Group: Good Policy: MAD etc. etc.
其中有100多个，而且显然不仅仅是名称，组，策略这3个元素.
Table2/Output2 Name: Abc Limit: 10 used: 5 Name: redi Limit: 20 used: 1 etc. etc.
其中
100个.
以及另外13个这些文本文件表，所有这些表的名称"都是唯一的.
如何使用Name和所有其他元素最后将其组合为一个输出?
我最明显的想法是某种类似于加入的东西，即使我一次必须做一次，但即使我不知道该怎么做.
无论如何，PowerShell本身是否都可以执行此操作，而无需使用Python或SQL?
如果是，是否有一种方法可以在无效的位置组合字段?
如果不清楚结果是什么类型，我希望它看起来类似于以下内容:
Name: Abc Group: Bad Policy: Great Limit: 10 used: 5 Name: redi Group: Good Policy: MAD Limit: 20 used: 1
所以我找到了一个更合适的答案，它使用了下面定义的 join-Object 函数:
您可以通过 https://github.com/RamblingCookieMonster访问它/PowerShell/blob/master/Join-Object.ps1
我真正要做的就是将我的输出定义为$ A和$ B和$ C等，然后
$Join1= Join-Object -Left $A -Right $B -LeftJoinProperty Name - RightJoinProperty Name
先制作$ Join2，然后再制作3个，直到我完成所有任务
$Join2 = Join-Object -Left $Join1 -Right $C -LeftJoinProperty Name -RightJoinProperty Name
$Join3 = Join-Object -Left $Join2 -Right $D -LeftJoinProperty Name -RightJoinProperty Name
$Join4 = Join-Object -Left $Join3 -Right $E -LeftJoinProperty Name -RightJoinProperty Name
直到我完成所有任务
How do we make Inner-Join or something a Cross-Join in PowerShell or PowerCLI?
Even though im new to PowerCLI/PowerShell , I do have a basic grasp on them, yet have practically spent 2 days trying to figure this, going through numerous documentations and blogs to no avail.
All I really want to know is if after typing my command
Get-Content File.txt
and getting:
Output1 or Table1 is Name: Abc Group: Bad Policy: Great Name: redi Group: Good Policy: MAD etc. etc.
100s of these, and obviously more than just the 3 elements of Name, Group, Policy each.
Table2/Output2 Name: Abc Limit: 10 used: 5 Name: redi Limit: 20 used: 1 etc. etc.
100s of these.
and like 13 more of these text file tables, all with the "Name" as unique.
How can I combine it into one output at the end using Name with all the other elements?
My most obvious thought was something akin to joins, even if I had to do them 1 at a time, but even that I cant figure out how to do.
Is there anyway to do this in PowerShell itself without me having to go into Python or SQL?
If yes is there a method that is able to combine fields in spots where it's null?
If its not clear what type of result I am hoping for it will look something akin to this:
Name: Abc Group: Bad Policy: Great Limit: 10 used: 5 Name: redi Group: Good Policy: MAD Limit: 20 used: 1
So I found an Answer which was more suitable and it uses the join-Object function which was defined below:
you can access it at https://github.com/RamblingCookieMonster/PowerShell/blob/master/Join-Object.ps1
All I really had to do was Define my outputs as $A and $B and $C and so on, and just
$Join1= Join-Object -Left $A -Right $B -LeftJoinProperty Name - RightJoinProperty Name
made $Join2 then 3 so on until I got it all done
$Join2 = Join-Object -Left $Join1 -Right $C -LeftJoinProperty Name -RightJoinProperty Name
$Join3 = Join-Object -Left $Join2 -Right $D -LeftJoinProperty Name -RightJoinProperty Name
$Join4 = Join-Object -Left $Join3 -Right $E -LeftJoinProperty Name -RightJoinProperty Name
Until I got it all done
