爲帳戶創建一個Apex觸發器，以根據自定義字段將送貨地址郵政編碼與賬單地址郵政編碼匹配

trigger AccountAddressTrigger on Account (before insert, before update) {
    for(Account a : Trigger.new){
        If (a.Match_Billing_Address__c == true && a.BillingPostalCode!=Null) {
            a.ShippingPostalCode = a.BillingPostalCode;
        }   
    }
}
