我正在尝试使用 Salesforce API(使用自定义 PatronManager 对象)构建应用程序,当我运行以下“父对子”查询时,我收到一条错误消息,指出无法理解该关系:
SELECT Name, (SELECT PatronTicket__InstanceDate__c FROM PatronTicket__EventInstance__r) FROM PatronTicket__TicketableEvent__c
但是,当我反转它并运行“子到父”查询时,它可以完美运行:
SELECT PatronTicket__InstanceDate__c, PatronTicket__TicketableEvent__r.Name FROM PatronTicket__EventInstance__c
谁能解释为什么父母对孩子的查询会给我一条错误消息?
谢谢!

我将 PHP Toolkit 与 Enterprise WSDL 一起使用,我收到以下错误消息:
