Question

我有一个代码为

的批次类

public class BatchDeleteEvents实现Database.Batchable，Database.Stateful，Database.AllowsCallouts {

private String query;
private String pageToken ;
private String CalendarId;
private String accessToken;
public BatchDeleteEvents(String CalendarId, String accessToken){

    this.query = 'Select Id, Name from Event__c'; // Query to get the CalendardID (Google ID)
this.CalendarId =CalendarId;
this.accessToken =accessToken;
}

public Database.Querylocator start(Database.BatchableContext BC){

    return Database.getQueryLocator(query);

}

public void execute(Database.BatchableContext BC, List<sObject> scope){
System.debug('Entered in delete Batch');
for(Event__c c : (List<Event__c>)scope)
 GCalendarUtil.doApiCall(null,'DELETE','https://www.googleapis.com/calendar/v3/calendars/'+CalendarId+'/events/'+c.name,accessToken);


    delete scope;
    }
public void finish(Database.BatchableContext BC){   
  for(CalendarSettings__c c: [Select Id, Name, CalendarId__c,CalendarQuery__c,FieldToDisplay__c from CalendarSettings__c])
     {  BatchPublicCampaignsToGoogle bjob = new BatchPublicCampaignsToGoogle(c.CalendarQuery__c,c.CalendarId__c,c.FieldToDisplay__c);
        Database.executeBatch(bjob,9); // This is set to process 9 records, allowing 1 extra callout for refresh token in case needed.
    }
    }

    }

我正在用批次9运行它

BatchDeleteEvents del = new BatchDeleteEvents（c.CalendarId__c，accessToken）; Database.executeBatch（DEL，9）;

我正面临错误

FATAL_ERROR|System.DmlException: Delete failed. First exception on row 0 with id a0290000007fCbEAAU; first error: ENTITY_IS_DELETED, entity is deleted: []

Class.BatchDeleteEvents.execute: line 26, column 1

我没有使用删除命令的地方为什么我面临这个错误任何一个请帮忙??

也许您删除了for循环中的所有范围将其更改为

for(Event__c c : (List<Event__c>)scope){
  GCalendarUtil.doApiCall(null,'DELETE','https://www.googleapis.com/calendar/v3/calendars/'+Cal   endarId+'/events/'+c.name,accessToken);

 }
 delete scope;

FATAL_ERROR | System.DmlException：删除失败。第0行的第一个例外
