Triggers 创建一个触发器，每当Salesforce中有新的Opportunity时，该触发器将创建一个新的Opportunity Owner

我是Salesforce的新手，我正在尝试创建一个触发器，它基本上会在每次添加新的Opportunity时更新字段并创建一个新的Opportunity owner

为清楚起见，我在下面附上了我的代码：

 trigger trig_Opportunity_CreateOppOwner on Opportunity (before insert, before update) {
     //Opportunity OppOwner = null;
     List<id>OppsID = new List<id>(); //Get the id of all new Opportunities owners

     for (Opportunity Opp : Trigger.new) { //If a new Opportunity is added, then create new OppOwner, if not, then don't add.
         OppsId.add(Opp.ID); //adds all new Opportunities Id's
     }

     List<Opportunity>OppToUpdate = [SELECT Id,
                                            Name,
                                            Owner__c,
                                            OppOwner,
                                     FROM Opportunity
                                     WHERE Id IN: Opp.ID // Select Id, OpportunityName,
                                    ];

     if Trigger.oldMap.get(opp.id).Owner__c != Trigger.oldMap.get(OppToUpdate.id).Owner__c // verify that if previous Opportunity has a matching owner.
        OppsId.add(Opp.ID); //populates new oppowner with ID's of all owners.

这基本上就是我要做的： 触发器更新前、插入前{

获取所有触发的机会。 验证旧Opportunity是否已具有匹配的所有者。 如果不是匹配的所有者，请更新Opportunity字段并更新Opportunity。

我不知道如何从第2步到第3步。任何帮助都将不胜感激。

由于您提供的代码不清楚它在哪里完成，从我的角度来看，似乎在几行之后，您提供了另几行。您可以发布您的所有代码吗？如果不是这样，那么您发布的代码就是您的所有代码，f从我的角度来看，这段代码什么都不做，绝对没有

为什么?

没有验证的错误 没有DML操作

   trigger trig_Opportunity_CreateOppOwner on Opportunity (before insert, before update) {
 //Opportunity OppOwner = null;
/* 
     List<id>OppsID = new List<id>(); //Get the id of all new Opportunities owners
     for (Opportunity Opp : Trigger.new) { //If a new Opportunity is added, then    create new OppOwner, if not, then don't add.
         OppsId.add(Opp.ID); //adds all new Opportunities Id's
     }
*/
     // 3 started lines might be replaced by the following one
     List<id>OppsID = Trigger.newMap.getKeys();
    //but the following code perform select on Opportunity object and return the same list as Trigger.new
    // OppToUpdate == Trigger.new 
    // What for? May be you should work with this part on "after insert/update"
     List<Opportunity>OppToUpdate = [SELECT Id,
                                        Name,
                                        Owner__c,
                                        OppOwner,
                                 FROM Opportunity
                                 //WHERE Id IN: Opp.ID // Opp - isn't exist and it  isn't list/set of id
                                 WHERE Id IN OppsId // I guess you meant this
                                ];
     // 1.variable "opp" isn't exist here
     // 2. "OppToUpdate.id" - you can't use list in this manner
     if Trigger.oldMap.get(opp.id).Owner__c != Trigger.oldMap.get(OppToUpdate.id).Owner__c // verify that if previous Opportunity has a matching owner.
    OppsId.add(Opp.ID); //populates new oppowner with ID's of all owners.

触发器在before上下文中运行，该上下文在将记录提交到数据库之前在内存中的记录上运行。在本例中，对触发器运行的记录所做的所有更改都将被调制，而无需执行DML语句。但是，您的其他注释是正确的。我指的是在其他对象上的DML，如活动、acc挂载、联系等。
