代码如下

string Filter = "ServiceCallID eq " + ticketID + " and day(DateCreated) eq " + day + " and month(DateCreated) eq " + month + " and year(DateCreated) eq " + year;

                    }
                    catch (Exception ex)
                    {
                        LogFile(ex.ToString());
                    }

数据正在插入，但是当我们更新数据时，我们就会收到错误，如上所述。我们无法确定确切的问题。请帮我找出这个问题。
