獲得在Salesforce

Question

開放活動的名單上有檢索相關的自定義對象活動OpenActivities的列表爲自定義對象啓用。對於讓我用這樣的查詢

public List<OpenActivity> getActivity1(){ 

return [SELECT Subject from OpenActivities Where WhatId= :ApexPages.currentPage().getParameters().get('id') ]; 

} 

列表，當我將它保存它是給我的錯誤

Error: Compile Error: sObject type 'OpenActivities' is not supported. If you are attempting to use a custom object, be sure to append the '__c' after the entity name. Please reference your WSDL or the describe call for the appropriate names. at line 44 column 8 

任何一個可以請告訴我如何檢索在Salesforce開放活動，是關係到特定的記錄對象的名單？

Answer 1

，因爲它在這裏描述你應該使用查詢： http://www.salesforce.com/us/developer/docs/api/Content/sforce_api_objects_openactivity.htm

例如

List<Account> a = [SELECT (SELECT ActivityDate, 
            Description, 
            Subject 
          FROM OpenActivities) 
        FROM Account]; 

for (Account a: l) { 
    System.debug(a.OpenActivities); 
} 

Answer 2

正確答案是：

List<Account> a = [SELECT (SELECT ActivityDate, 
            Description, 
            Subject 
          FROM OpenActivities) 
        FROM Account]; 

for (Account l: a) { 
    System.debug(l.OpenActivities); 
}
