Salesforce Apex： - 以静态方式获取错误只能用于顶级类型的方法

Question

在开发人员控制台上，将错误视为静态只能用于顶级类型的方法

采用DML语句输入的静态方法

public class InvoiceHandler {     public static APEX_Invoice__c insertNewinvoice（今天的日期）{         列表invoiceList = [SELECT id，Name，APEX_Status__c，createdDate FROM APEX_Invoice__c WHERE createdDate = today];         return invoiceList;     } } 此方法采用名称日期参数并生成新发票。它将返回该invoiceList。

如果我只在下面执行 列出invoiceList = [SELECT id，Name，APEX_Status__c，createdDate FROM APEX_Invoice__c WHERE createdDate = today];

代码已成功执行，但我的意图是通过类和静态方法执行

如果您正确缩进代码会有所帮助..

public class InvoiceHandler 
{ 
    public static List<APEX_Invoice__c> insertNewinvoice(date today) 
    { 
        List<APEX_Invoice__c> invoiceList = [SELECT id, Name, APEX_Status__c, createdDate FROM APEX_Invoice__c WHERE createdDate = today]; 

        return invoiceList; 
    } 
}
