我正试图将mysql数据库中的数据解析到powershell中，然后使用这些数据根据powershell变量upn更新ad帐户，但我无法使mysql数据和powershell变量正常工作。我不是一个sql的家伙，所以不确定它是否与mysql语法或powershell脚本的编写方式。
这是脚本末尾的命令，我无法使用它，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

[string]$sConnectionString = "server="+$sMySQLHost+";port=3306;uid=" + $sMySQLUserName + ";pwd=" + $sMySQLPW + ";database="+$sMySQLDB+";SslMode=none"

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

    $oConnection.Open()
    write-warning ("it connected")

}

    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) {
