使用 powershell 变量查询 MYSQL 数据库

Question

我正在尝试将 MYSQL 数据库中的数据解析到 powershell 中，然后使用该数据根据 powershell 变量和 upn 更新 AD 帐户，但我无法获取 MySQL 数据和 powershell 变量才能正常运行。我不是 SQL 人，所以不确定它是否使用 MYSQL 语法或 powershell 脚本的编写方式。

这是脚本末尾的命令，我无法运行，但我在下面包含了整个代码

$mysqlquery1 =  Invoke-MySqlQuery -Connection $oConnection  -Query 'Select * from user_informations where login='"$user.sAMAccountName"

#
# Script.ps1
#
$GetUsersemail = Get-ADUser -Filter * -Properties mail, sAMAccountName, userPrincipalName -SearchBase "OUNAME"| Where-Object {($_.mail -ne $null)} | Select-Object mail,sAMAccountName,userPrincipalName

Import-Module activedirectory
Set-Location C:\MySQL\MySQL-master
Unblock-File -Path .\MySQL.psm1
Import-Module .\mysql.psm1

[System.Reflection.Assembly]::LoadWithPartialName("MySql.Data")
[string]$sMySQLUserName = sqluserid
[string]$sMySQLPW = 'password'
[string]$sMySQLDB = 'DB'
[string]$sMySQLHost = 'IP'
[string]$sConnectionString = "server="+$sMySQLHost+";port=3306;uid=" + $sMySQLUserName + ";pwd=" + $sMySQLPW + ";database="+$sMySQLDB+";SslMode=none"

$oConnection = New-Object MySql.Data.MySqlClient.MySqlConnection($sConnectionString)
$Error.Clear()

try

{
    $oConnection.Open()
    write-warning ("it connected")
$dataSet = New-Object System.Data.DataSet
}
catch
{
    write-warning ("Could not open a connection to Database $sMySQLDB on Host $sMySQLHost. Error: "+$Error[0].ToString())
}




ForEach ($user in $GetUsersemail) {
    $spn = $null
    $fullemail = $null
    $spnsplit = $user.mail.split("@")
    $spn = "@" + $spnsplit[1]
    $fullemail = $user.sAMAccountName + $spn

        if ($fullemail -ne $user.userPrincipalName) {


    Switch ($spn) {
            "@upn1.com" {
                Set-ADUser -UserPrincipalName $fullemail -Identity $user.sAMAccountName
                           }
            "@upn2.com" {   
                    Set-ADUser -UserPrincipalName $fullemail -Identity $user.sAMAccountName
                             }
             "@upn3" { 
                    Set-ADUser -UserPrincipalName $fullemail -Identity $user.sAMAccountName
                    }
            "@upn4" {
                    Set-ADUser -UserPrincipalName $fullemail -Identity $user.sAMAccountName
                    }
             "@upn5" {
                    Set-ADUser -UserPrincipalName $fullemail -Identity $user.sAMAccountName
                    }
              "@upn6" {
                    Set-ADUser -UserPrincipalName $fullemail -Identity $user.sAMAccountName
                    }
              "@upn7" {
                    Set-ADUser -UserPrincipalName $fullemail -Identity $user.sAMAccountName
                   }
               "@upn8" {
                    Set-ADUser -UserPrincipalName $fullemail -Identity $user.sAMAccountName
                    }
                    }
                    }

               $mysqlquery1 =  Invoke-MySqlQuery -Connection $oConnection  -Query 'Select * from user_informations where login='"$user.sAMAccountName" 
    }

   $oConnection.Close()

Answer 1

您需要小心 PowerShell 字符串引用；单引号字符串 'abc' 内部不能有变量，双引号字符串 "abc" 可以，例如"abc $xyz" 但您不能使用 "abc $xyz.property"，因为 PowerShell 将 .property 视为文本的一部分，而不是变量的一部分。为此，您需要一个子表达式，"abc $($xyz.property)"

根据您需要字符串最终被引用的方式，尝试：

"select * from user_informations where login='$($user.sAMAccountName)'"

双引号在外面，所以你可以把单引号和子表达式放在里面。结果应该是这样的：

select * from user_informations where login='john.hancock'

（应该是user_information，单数吗？）
