如何在數組上的 Powershell 中使用 foreach

Question

我正在查詢 MySQL 數據庫並獲取我需要的僅有的 2 列 alert_limit 和 customer_email。 我計划能夠分別使用警報限制值 select email，並將它們用作 SMTP 參數的變量。

更新：為了回答 Luuk 的問題，我正在使用 SimplySql Powershell 模塊。 https://www.powershellgallery.com/packages/SimplySql/1.6.2

$query = Invoke-SqlQuery -query "SELECT distinct alerts.* FROM alerts, joblog Where alert_enabled=1 and joblog.customer_id=alerts.customer_id AND alert_limit;"  | select "alert_limit", "customer_email"

結果是：

alert_limit customer_email             
----------- --------------             
        150 user1@email1.com 
      12000 user2@email2.com 
      10000 user3@email3.com

我正在嘗試將個人 email 發送到每個 customer_email 並在正文中限制）如下：

$Parameters = @{
    ToAddress   = '$customer_email'
    FromAddress = "notifications@system.com"
    Subject     = "Credits"
    Body        = "your credits are bellow" '$alert_limit'

但我努力爭取 select 個人條目。 謝謝

我已經做了。

 ForEach($customer in $query) {

   $alert_limit= $customer.alert_limit
   $customer_email =  $customer.customer_email

$Parameters = @{
    ToAddress   ="$customer_email"
    FromAddress = "notifications@system.com"
    Subject     = "Credits"
    Body        = "your credits are below<br> $alert_limit"

}
}
